bug: cannot install complexipy

[cameronbrill]

Hi, complexipy seems super cool/useful, but I'm struggling to get it installed. Running pip install complexipy gives me the following error:

I am running on an Apple M1 Max Macbook pro on MacOS 14.4.1. My python version is 3.8.5. Am I missing some setup step?

hey @cameronbrill thank you for using complexipy, I'm gonna check this error and try to fix it, thank you for all the details, I also use a M1 Pro so I think I could reproduce this error!

[rohaquinlop]

@cameronbrill I was testing locally, and it seems that complexipy isn't working in python 3.8 due to the type hints that I'm using in the project, I couldn't install python 3.8.5 locally, but I installed complexipy in the version 3.8.19 and this is the version that fails during the execution of complexipy due to the type hints as I previously mentioned.

Already tested it in the version 3.9 and is working. Used the version 3.9.19.

I think that due to this issue, I will update the minimum python version to 3.9. Thank you so much for your contribution!
If you want to be a contributor and be listed at the contributor section, feel free to create a PR updating the minimum version to 3.9, pls relate that PR to this issue. ex: fix(build): #41 ...

Hi @rohaquinlop, thanks for the response! I just updated to python 3.9.18 but am still unable to install complexipy with the same error. fwiw this seems like a rust error, but I don't have any experience developing with rust so don't really know what to try next. Here's the important-looking part of the pip install complexipy error message:

      error: failed to select a version for `env_logger`.

@cameronbrill I'm still trying to figure out why it's giving you that error message 🤔

[rohaquinlop]

@cameronbrill found out that env_logger was an unused dependency, I removed the unused dependencies and published a new complexipy version, I think that you can try again to install complexipy.

just noticed this comment, I can't say if that fixed my issue as the project into which I was installing complexipy recently updated to python 3.10, but I'm able to install complexipy now! thanks for the help
