apparently you're supposed to provide the project name as an argument to npm init, eg.:

$ npm init wasm-app foo
npx: installed 1 in 2.211s
🦀 Rust + 🕸 Wasm = ❤

That seems to work fine, relevant code below:

if (process.argv.length >= 3) {
  folderName = process.argv[2];
  if (!fs.existsSync(folderName)) {
    fs.mkdirSync(folderName);
  }
}

const clone = spawn("git", ["clone", "https://github.com/rustwasm/create-wasm-app.git", folderName]);

Should we update the docs accordingly in order to reflect that? I can send a quick PR.

#84

I've made a pull request to display the error messages from git (since git is used in the implementation of npm init wasm-app) so that the error messages are actually useful for working out what went wrong when it fails.

I don't mean to bash anyone, especially not the devs of this project, but the fact that this seemingly trivial issue seems to be causing so much pain to so many people might be an indication that the CLI command's current terminal interface is far from intuitive, and likely to be suboptimal.

From first principles, it both surprises and bugs me that this is somehow tied up into npm init rather than being it's own, clean, unambiguous, documented and easy to use CLI command.

Compare this to using e.g. Cargo, which Just Works(tm) generally speaking. Meanwhile I'm fairly certain that what cargo does is far more complex than the rustwasm project creation CLI command that seems to be causing so much confusion and pain.

I found that this wasn't working for me because I had git configured to use a proxy. Running git config --global --unset http.proxy before npm init wasm-app www fixed it for me.

FWIW, I don't think that's the core issue, since I've have never had git configured to use a proxy.

The script for cloning the project is fairly simple.

Given the fact that this bug has existed since 2018 and still isn't fixed, I have to disagree with that assessment. It may look simple, but if it really was then the issue would have been fixed long ago. Rather it looks like there's some subtleties that are being overlooked somehow.

It also reminds me of the recently-introduced term builder gloves.

Do you have git on your machine?

Of course! What kind of dev doesn't these days? :)

Apparently not. Adding the project name randomly works on my machine. Out of 10 times, it worked only once.

npm: 6.9.0
node: v11.10.1

JonCB avatar JonCB commented on September 6, 2024

@tushartyagi Looks like cloning the template fails if the directory exists.

Note that your 1 success is the first time you added a folder name. This statement is blatantly not true... i should have looked at your image more carefully. At any rate the above solution (ensuring the directory does not exist) worked for me.

I also encountered this issue and thought I'd share what I found. When trying to run the command from the terminal in vscode I got the same error, but when running it from git bash it worked successfully. I've had issues cloning from certain repos before because of TLS issues on Windows and the version of Git I was using. The Git version in vscode is older then the version I have for Git bash. Not sure if this is the cause or not, but here's the output from both cases if anyone is looking into this.

git --version

npm init wasm-app www

cloning the template failed!

@jhessin try running git clone https://github.com/rustwasm/create-wasm-app.git from inside the www folder. That's what npm init wasm-app www does anyway.

@jjpe

From first principles, it both surprises and bugs me that this is somehow tied up into npm init rather than being it's own, clean, unambiguous, documented and easy to use CLI command.

Running this npm init command runs a script (create-wasm-app.js). This is equivalent to "it's own [...] easy to use CLI command". The command is already:

  • "clean" and "easy to use": run one command to acheive the task
  • "unambiguous" and "documented": This is a normal way to make a new JavaScript project from a template. See unambigous documentation here.

Compare this to using e.g. Cargo, which Just Works(tm) generally speaking. Meanwhile I'm fairly certain that what cargo does is far more complex than the rustwasm project creation CLI command that seems to be causing so much confusion and pain.

The script for cloning the project is fairly simple. Compare it to the slightly more complicated create-express-api. It may be performing a simple task, but because of the way that npm init works (and it makes sense to use npm init in this case) you have to make a script specifically for this scenario, and this script hasn't had as much time put into it or as many people contributing to it as Cargo. The main problem seems to be a lack of helpful error messages which will hopefully be fixed by my aforementioned pull request (#84).

darkmou5e avatar darkmou5e commented on September 6, 2024

Looks like npm init wasm-app fails because a git repo is already initialized in the current directory. If a new project name isn't specified the script tries to do git clone https://github.com/rustwasm/create-wasm-app.git . and gets fatal: destination path '.' already exists and is not an empty directory.

Had the same issue - just like RKennedy9064 commented, updating git (from 1.7.x to 2.26.2) fixed the issue for me.
