Install fails with "ModuleNotFoundError: No module named 'imp'"

[T313C0mun1s7]

Describe the bug

Python 3.12+ is currently unsupported, trying to install tl will result in an error due to missing the imp module.

Expected Behavior

Install successfully with no error.

Current Behavior

Install will produce an error that says:

ModuleNotFoundError: No module named 'imp'

According to the Python documentation, imp was deprecated in Python 3.4, and removed in 3.12.

Steps to Reproduce

1. Install Python 3.12.x
2. Install tl with pipx install tl or pip install tl

So I am experiencing the issue because this pull request is not yet merged? (I'm kinda just guessing here)

If it is preventing even installation, is this not an urgent issue? Is there any kind of timeline on when the pr might get merged?

You are trying to use python 3.12.

If it is preventing even installation, is this not an urgent issue?

No. Toolong supports python 3.8. you are trying to use a newer python version.

Is there any kind of timeline on when the pr might get merged?

No timeline. It's a question of when the maintainer has time or inclination to look at it.

I created the PR because I wanted to use a newer version of Textual with toolong, and that required a newer version of python.

HTH.

Toolong doesn't use imp, which indicates either a dependency or the builds system.

if it doesn't run with Python 3.12, try using 3.11

pipx install --python 3.11 tl
