sounds like evdev didn't install correctly. in the command line, try this:

sudo pip3 install evdev

if it installs, then great! restart gpionext with the command

gpionext start

if you get the message

Requirement already satisfied: evdev in /usr/local/lib/python3.5/dist-packages

then we'll have to dig a bit further

from gpionext.

You were right, the problem was a bad evdev installation.
Sorry for the false issue reported

from gpionext.

nah, It's no problem. Eventually I'd like to rewrite the installer so that it runs checks for this kind of stuff.

from gpionext.

I also seem to be getting this error, unfortunately for me sudo pip3 install evdev gives me "sudo: pip3: command not found"

I've tried every method I can find online to install pip3 but nothing I do seems to work. It's as if it can't find anything pip or pip3 related in the repository or something.

I'm running Raspbian for a retropi project i'm building.

Any help you could give would be much appreciated.

from gpionext.

try this and let me know any errors that it outputs.

sudo apt-get install python3 python3-pip python3-dev gcc

from gpionext.

Thanks very much for helping me out. Unfortunately this is what I get ;

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python3-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Unable to locate package python3-pip
E: Package 'python3-dev' has no installation candidate

Thanks Again

ok, make sure that your APT repositories are up to date:

sudo apt-get update
sudo apt-get dist-upgrade

then run
sudo apt-get install python3-dev python3-pip

from gpionext.

Well, I got further than before.

sudo apt-get update - was already up to date
sudo apt-get dist-upgrade - this did a fair amount (I had been trying sudo apt-get upgrade no "dist-"

After the upgrade I then was able to install python3-pip, but not python3-dev.

When I try to run gpionext configure I now get a different error;

Traceback (most recent call last):
File "/home/pi/GPIOnext/config_manager.py", line 10, in

ModuleNotFoundError: No module named '_sqlite3'

I tried sudo apt-get install libsqlite3-dev, but got this;
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libsqlite3-dev

If it helps I check the repo links and uncommented the bottom ones (online forum advice for someone else with a similar problem:

deb http://raspbian.raspberrypi.org/raspbian/ stretch main contrib non-free rpi

Uncomment line below then 'apt-get update' to enable 'apt-get source'

deb-src http://raspbian.raspberrypi.org/raspbian/ stretch main contrib non-free rpi

Thanks again, I know I'm a pain.

from gpionext.

Also tried this;

sudo pip3 install sqlite3
Collecting sqlite3
Could not find a version that satisfies the requirement sqlite3 (from versions: )
No matching distribution found for sqlite3

sudo pip3 install libsqlite3
Collecting libsqlite3
Could not find a version that satisfies the requirement libsqlite3 (from versions: )
No matching distribution found for libsqlite3

from gpionext.

you have packages missing from your install, you need to install the python3-dev
but it sounds like your sources list is borked, which is out of scope for this trouble-shooting.

If you are interested, your sources list is located at /etc/apt/sources.list

from gpionext.

I checked those before I posted and both /etc/apt/sources.list & sources.list.d seem to be what they should be.

Thanks for your help, I guess I'll try wiping Raspbian & starting from scratch.

from gpionext.

ok, yeah, it seems like something must have messed up on the initial install. I think that you are correct, a fresh install is probably the best course of action.

from gpionext.

I started from scratch, no idea what happened with the first install I did but GPIOnext works perfectly now.

Thanks very much for your help & time. Thanks for GPIOnext too, it's great and will save me a lot of extra work!!

from gpionext.

Great! Glad it's working now!
