So I made a small little command-line utility for myself just for practice, but I had a hard time figuring out how to actually turn it into something I can just use on the command line with no fuss. It uses a virtual environment as Python packages should, so it needs to be run in that environment and I was having trouble figuring out how to do it.

But then I remembered that pipx runs application in a virtual environment, and after checking the docs, I found out that it allows installing local packages by just pointing install at the package directory. So I did, and after setting up the command name as a project script that points to main it ended up working.

I haven’t ever heard of anyone doing something like this for a personal program though. Is something like this a bad idea? Is it over engineering or error prone? Is there another way that most people do something like this?

    Perfect use case. pipx is awesome for Python! Glad you found a great easy solution.

    Is it over engineering or error prone?

    Nope. pipx is like a big guard rail to keep you from doing error prone things with system Python.

    In these examples we’ll assume your venv is at /home/TrueBlue/project/venv

    Is there another way…?

    • shebang: Set your #! to point at your Python venv runtime
      #!/home/TrueBlue/project/venv python3
      Now you can just run your Python file and it’ll use the correct Python runtime.
    • poetry can be useful for running personal projects using poetry run.
    • In linux you can use an alias to create to call your venv Python runtime with your package.

    e.g. I want to use a new command named sdf to call my app.

    alias sdf="/home/TrueBlue/project/venv/bin/python3 my_app.py"
