CLI library incompatibility with Pyinstaller?

[Bede Constantinides]

Greetings installers of Python,

I'm having problems using Pyinstaller for both of my CLI applications that use a library called defopt (https://github.com/anntzer/defopt) for building subcommand-based CLIs. I've tried --onedir and --onefile. I'm using MacOS 12.4

Since I get similar errors for two completely different packages, I assume that there is an incompatibility here? This lends the question with what should I replace defopt? I want to use something I know will work with Pyinstaller.

Building goes ok with a few warnings:

```

pyinstaller --onefile --name konstel konstel/cli.py

```

Running does not

```

dist % ./konstel
