Can't run/install Python script

Support Third-party Applications
1

I installed Manjaro KDE on my new PC and I’m trying to install this now:

It makes the mouse wheel experience on Linux infinitely better. I have installed it many times on Debian/Ubuntu based distros with no problems.

According the instructions one should do:
pip install -r requirements.txt
(I used pip3 instead - the result is the same)

But I get this message:
Mod edit: Removed a picture of text. See: [HowTo] Post command output and file content as formatted text

I’m not sure what it means nor how to solve it.
Any input would be appreciated.

If you wish to install a non-Arch-packaged Python package, create a virtual environment using ‘python -m venv path/to/venv’. Then use path/to/venv/bin/python and path/to/venv/bin/pip.

:arrow_down:

cd mouse-scroll-wheel-acceleration-userspace
python -m venv venv
source venv/bin/activate

Now do your pip stuff in a virtual environment and not globally. We saw lot of users who have conllicts between pacman and pip, since they use the same folders as root. Then people come and say: “Oh pacman/pamac cannot upgrade! Plz Halp” etc. Please avoid that. The error, which was introduced upstream by pip devs, should be clear.

Since the script is a user space implementation, it should not need to have root access. User mode is more than enough.

Thanks for detailed explanation!
The installation itself works with those instructions, but the service doesn’t seem to be able to start/run:

systemctl restart --user mouse-scroll-wheel-accelerator

No errors or output, but it’s not starting. I assume it has something to do with that venv?

You are correct.

The environment needed for the service is not available.

Thanks for confirming, so how can I get around that?
I really would like to run that “wheel mod” somehow.

Well just a bit searching… example: How to create a systemd service for python script with virtualenv · GitHub

Edit it:

systemctl --user edit --full mouse-scroll-wheel-accelerator.service

and change it something like that:

[Unit]
Description=Mouse scroll wheel accelerator

[Service]
WorkingDirectory=/tmp/mouse-scroll-wheel-acceleration-userspace/
Environment=PYTHONPATH=/tmp/mouse-scroll-wheel-acceleration-userspace/
ExecStart=/tmp/mouse-scroll-wheel-acceleration-userspace/venv/bin/python main.py
Type=simple
Restart=always

[Install]
WantedBy=default.target

Adjust the paths to your needs.
