Error: EPERM: operation not permitted, mkdir 'C:\Users\Foo' about npx HOT 93 OPEN

I was able to fix this in Windows by creating a directory junction to my users folder that didn't have a space in it. You can run a command like this in an administrative powershell:

cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"

You can then use this junction as if it were your real user directory:

npm config set cache C:\Users\myname\AppData\Roaming\npm-cache
npm config set prefix C:\Users\myname\AppData\Roaming\npm

(the above should update your user .npmrc file)

from npx.

I had the similar issue. Got fixed just by cleaning the npm cache.

npm cache clean

from npx.

running cmd through administrator works for me

from npx.

If anybody still have this issue. I got it resolved using npm install -g create-react-app and then npx create-react-app <appname>

Make sure your appname doesn't have any capital letters.

from npx.

The @manojkumardesai solution has worked for me just fine.

npm install -g create-react-app
npx create-react-app <app-name>

from npx.

@manojkumardesai thanks for sharing

Below steps worked for me

npm install -g create-react-app
npx create-react-app <appname>

from npx.

npm clean cache doesn't work. No NPM commands work. They are all result in this same error. Even npm -v

from npx.

I think you should excute this command on administrator "npm config set prefix path/to/Actual_npm_folder"

from npx.

My user name was "C:\Users\Carolina Maciel" i used:

1º)cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"
2º) npm config set cache C:\Users\myname\AppData\Roaming\npm-cache
3º) npm config set prefix C:\Users\myname\AppData\Roaming\npm

if not work, use:
npm cache clean --force

Worked for me, hope helps for u!

from npx.

I also have this issue, although it is failing on mkdir of a username with a space in it, that is not on my computer. Is this a config setting I should change (maybe it somehow mixed up user config that I had on an old computer)?

Fixed
Did a search for .npmrc file, and changed prefix= to the correct user.

from npx.

Removing npmrc worked for me

from npx.

I think i set the "npm config set prefix= to something" mistakenly due to which i was getting the error. Here's how i fixed it:
Open CMD in "Administrator" mode.
npm cache clear --force
npm install
npm config set cache C:\Users\myname\AppData\Roaming\npm-cache
npm config set prefix C:\Users\myname\AppData\Roaming\npm

Happy coding.

from npx.

Heres is my solution:
npm install -g create-react-app
npx create-react-app my-app
cd my-app
npm start
the only thing i think about is making sure npx is up to date.

from npx.

find the NPMRC file located in C:\Users\ . oped this file in text editor and remove what ever is written there like "prefix=C:/Program Files/nodejs/npm_global" and save again . now run NPM command it will work :)

from npx.

@manojkumardesai Thank you

npm install -g create-react-app
npx create-react-app

works

If you are looking into this problem with using Microsoft Visual Studio, Run Microsoft Visual Studio as Administrator and the problem will be solved.

from npx.

I think npx is working for me now, though it always says

npx: installed 1 in 1.784s
command not found: prefix

before printing the command output. Anyway, none of the "fixes" posted before the one @edwardbrowncross wrote worked for me. I believe that a bunch of people in this thread actually have a totally unrelated problem with a similar stack trace. The actual issue (spaces in your Windows profile directory path) is supposed to be resolved by #181, though I have no idea why that hasn't been merged yet.

In the interim, if you have this issue, you can fix it without administrative privileges. On my machine, I only have to specify cache in my .npmrc, not prefix, and I set it to c:\Users\jamesb~1\AppData\Roaming\npm-cache. Note that jamesb~1 -- that's the generated 8.3 filename (for DOS compatibility) that matches my actual user profile dir. You can view these short names with dir /x, if need be.

from npx.

I was able to fix this in Windows by creating a directory junction to my users folder that didn't have a space in it. You can run a command like this in an administrative powershell:

cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"

You can then use this junction as if it were your real user directory:

npm config set cache C:\Users\myname\AppData\Roaming\npm-cache
npm config set prefix C:\Users\myname\AppData\Roaming\npm

(the above should update your user .npmrc file)

Life Saver.. Love you man

from npx.

Consider the following flow:

1. A new user on Windows 10 decides to try out Node + React.
2. They install Node 10.15.1 LTS from the main site .
3. They try running npx create-react-app my-app; it fails with the mentioned EPERM error.
4. They try running npm init react-app my-app, alternate command mentioned on React site; same error.
5. The user spends 30 minutes tracking down this issue in GitHub.

All Windows users with a space in their filename will encounter this issue. It looks like there was some movement at #181 , but then the work tailed off and wasn't merged. Perhaps if the proper fix can't get completed anytime soon, a more informative message could get printed when the problem is detected.

from npx.

@manojkumardesai Thank you

npm install -g create-react-app
npx create-react-app

works

This work for me too

I noticed that the path in the error message cut off prior to the first space. The path to my user folder is 'C:\Users\Paul Cyr'.

Am I reading this right, that there's a fix (#138) but until it gets merged, npx doesn't work on Windows (if my profile dir has a space in it)? Bummer, I just found out about npx today and got all excited to stop typing ./node_modules/.bin so much...

from npx.

I can confirm that @edwardbrowncross 's method works. Thanks!

from npx.

if you have node version less than 10 but greater than 8.10 installed on your system.Then follow below method
First install create-react-app ->
npm install -g create-react-app
Then using npx write following command on command prompt or bash->
npx create-react-app

Else pls upgrade your node version to 10 and use following command only to create a react app
npx create-react-app

Cheer up

from npx.

Workarounds aside, is there any chance this gets fixed? The issue is quite old, but the issue still remains.

from npx.

Any update on when the fix for this will be included? It is popping up through more and more modules

from npx.

@falakejaz Do you mean npx create-react-app? npm create-react-app won't work

from npx.

@manojkumardesai : fix your spelling of 'create' as asked by @pasunmaa

from npx.

thanks @manojkumardesai !! worked for me

from npx.

I still have this problem (just tried with react-styleguidist). I have tried previous suggestions but to no avail:

• I tried removing my .npmrc (C:\Users\Toke Voltelen\.npmrc)
• I tried adding prefix=C:\Users\Toke Voltelen to the .npmrc
• I have cleared npm cache (npm cache clean --force)

I am not sure what else to try at the moment.

NPM Version : 6.2.0
OS: Windows 10 Home 64 bit

from npx.

So I just solved the problem BUT I took the longest and most stupid path so, please, don't do it: I've changed my Windows username (without spaces this time, of course) -> changed user name folder (without spaces) -> had to waste like 4 hours manually cleaning the registry (regedit -> find "old username" -> change it -> f3 to see next). So now npx works for me.
@hdwebpros Yes I did, but it didn't work.

from npx.

This is work for me,I got it resolved using npm install -g create-react-app and create project npx create-react-app myapp

from npx.

It's a escape error, this escape for / path works for me: "\/"

platform is win10

from npx.

I found these solutions, which worked for me!

#146 (comment)

You need to change the cache to a location without spaces.

from npx.

npm cache verify
npm cache clean --force

i'm have a try!!

from npx.

Heres is my solution:
npm install -g create-react-app
npx create-react-app my-app
cd my-app
npm start
the only thing i think about is making sure npx is up to date.

This worked for me as well (still having space in my username on Windows 10)

from npx.

@Meeeeow could you post the actual terminal output for this, please? I'm not exactly sure which place it's coming from with just this info.

from npx.

Thanks! This looks like a bug in npm itself. I'll look into it!

I have the same problem but I have only encountered it with 2 modules so far.
NVM for windows and TSlint.

I was hit with the same problem, same backtrace, and for the same reason as the OP .

It works fine for IIS Express but as soon as I try to use it with IIS it fails.

from npx.

I think it is related to being admin, some how. For instance I just tried to install and if you check Building section it says;

//if use Windows:
npm config set prefix "C:/Program Files/nodejs/npm_global"
npm config set cache "C:/Program Files/nodejs/npm_cache"

I could set prefix but when I entered cache it gave the the typical error which everyone had above.
But when @patnaix said "running cmd through administrator works for me" , I opened Powershell as administrator and runned npc cache clean first. Then ran the commands above and done it without getting any error.

I hope it helps.

from npx.

@sampana worked for me as well.

from npx.

@legendarynacar I tried changing npm cache location, no error, but still does not for (the npx)

@sampana removing npmrc doesnt seem to work too

from npx.

This helped with a small correction: npm install -g create-react-app

from npx.

I was getting the same issue, npm cache clean fixed it for me :)

from npx.

I was getting the same issue as well. I tried

I tried removing my .npmrc (C:\Users\My Name.npmrc)
I tried adding prefix=C:\Users\My Name to the .npmrc
I have cleared npm cache (npm cache clean --force)
I ran CMD as admin
I tried running npm config set prefix path/to/Actual_npm_folder

That is where I found my issue. After running that, I saw that the .npmrc file had
prefix=C:\Users\My in it.
It should have read prefix=C:\Users\My Name\AppData\Roaming\npm instead.

I manually changed that .npmrc file (make sure its uncommented too) to use the correct path for NPM (check your system environment variables for that path).

Run your command again and hopefully it will work.

NPM Version : 6.1.0
OS: Windows 10 Home 64 bit

from npx.

Still have the same problem after every step @hdwebpros did.
I changed .npmrc file, got this npm ERR! Could not install from "JustTheSecondPartOfMyUser\AppData\Roaming\npm-cache_npx\9944" as it does not contain a package.json file.

NPM Version: 5.6.0
OS: Windows 10 Home 64 bit

from npx.

@vicfabrice Did you specifically open that file, and find that line, and manually change it and save?

That's what made it work for me.

from npx.

@vicfabrice That sucks, but at least you have it working now. Hopefully this issue gets addressed soon for other users.

Tell me what shuld i do?

cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"

@edwardbrowncross this is working for me as well. Thanks a lot!

from npx.

tried @edwardbrowncross method and unfortunately it broke npm completely for me

`C:\Users\My Username\Documents\Code\React>npm version
fs.js:1670
binding.stat(baseLong);

This exact error happens with npm <any_command> - not posting to criticise @edwardbrowncross but just one data point that this might happen if you try that solution.

from npx.

Update: deleting the symlink file created by the mklink command but not re-updating the caches seems to have both eliminated the above error and made npx create-react-app work

¯_(ツ)_/¯

thanks to @edwardbrowncross no thanks to computers

I was able to fix this in Windows by creating a directory junction to my users folder that didn't have a space in it. You can run a command like this in an administrative powershell:

cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"

You can then use this junction as if it were your real user directory:

npm config set cache C:\Users\myname\AppData\Roaming\npm-cache
npm config set prefix C:\Users\myname\AppData\Roaming\npm

(the above should update your user .npmrc file)

It says "Access Denied" when I use this command.

from npx.

It says "Access Denied" when I use this command.

The workaround works for me. Make sure to execute the first command in an administrative powershell (right-click, "Run as Administrator")

from npx.

It work for me to git pull.

Still seeing this issue while trying to use the npx command:

Any chance of this getting fixed?

@sudip1072 - What's the point of using npx if you just installed the command globally? npx is supposed to let you run a command WITHOUT installing it globally?

from npx.

Am I reading this right, that there's a fix (#138) but until it gets merged, npx doesn't work on Windows (if my profile dir has a space in it)? Bummer, I just found out about npx today and got all excited to stop typing ./node_modules/.bin so much...

Latest patch appears to be #181.

from npx.

As a further data point, my prefix was set and escaped to the right value and yet I still got the reported error message.

@edwardbrowncross' work-around worked for me.

Wiki sez about junctions: "Unlike NTFS symbolic links, junction points can only link to an absolute path and only to a local volume; junction points from a local volume to a remote share are unsupported."

In other words they may not work for everybody.

from npx.

Thanks @edwardbrowncross . I confirm this works fine.

from npx.

Thanks @edwardbrowncross
node -v v8.15.0 "C:\Users\My Name" change "C:\Users\myname" ok

from npx.

For those recommending to run as admin, this opens a large security hole as it creates a new folder with admin perms, potentially blocking all other non admin apps from doing anything at all.
The correct workaround (until the code is fixed) is to make npm think your home directory does not have a space in using @edwardbrowncross 's suggestion above.

from npx.

can anyone tell me how to fix this ????

1. Open CMD in "Administrator" mode.
2. npm cache clear --force
3. npm install

It's worked for me.

from npx.

Tried everything mentioned here, only solution for me was to change the user name

https://www.top-password.com/blog/rename-user-profile-directory-in-windows/

from npx.

I had this same issue, did a search for my .npmrc file and put this in my prefix.
prefix=${HOME}/.npm-packages
it's the general default config. In my case I accidently changed the default config path which ended up breaking it.

from npx.

CMD as administrator solved it for me

from npx.

I tried everything in this thread and nothing worked, then I installed Cmder and it magically worked...

from npx.

Try going to the file .npmrc, in "C:\Users%UserName%", and deleting it.

from npx.

I was also facing the same problem while following react tutorials. Following steps worked for me
I changed all the defaults path of node and npm from C:\Users\ {user name} to some other drive.

1. Installed the node to some other drive.
2. Moved npm to some other location(say D:\npm)
3. Changed the paths of npm from PATH env variable
4. Changed the paths of npm-cache, .global_variables, .npmrc to (D:\npm) using npm config set {command} = {path}
   This will override the existing settings and set the new ones.

After this I ran the npx command shown in tutorial, and it worked.

Hope this helps.

from npx.

@carolinamaciel1 Thanks, but as I said, this is a workaround.

There is a PR request readily available, which only needs to be merged to REALLY fix this problem.

@zkat My hope is on you ;-) Any change you could merge PR #181 ?

Life Saver.. Love you man

I'm searching for like an hour and finally, you made it nicely, thank you so much

from npx.

Seeing the same behavior here with respect to paths with spaces. Appears to be limited to npx.
npm cache verify has no effect.

Escaping the slash this way worked for me. Thank you very much. I'm also on windows 10. I do not have a space in my user name.

This problem started for me after calling this:
npm config -g set cafile

After the above I tried calling this and then I saw the error:

npm config -g set cafile C:\Users\XXXXXXXX\git-certs\cert_XXXXXXXX.pem
