Error installing solax package under WinPython

[petgriffin]

Hi

I am trying to install the solax package on my PC which is running Python via Winpython. The command line command is:

c:\WinPython\WPy64-31230\python-3.12.3.amd64\Scripts>pip install C:\Users\alun.griffiths\Downloads\solax-3.1.0.tar.gz --use-pep517

The argument --use-pep517 was suggested by pip after I tried a pip install without it, whcih failed. The output from the above command is given below. No idea how to fix this so would appreciate any suggestions. Many thanks!

      Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

      For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Hello, thank you for putting such a detailed bug report together! Unfortunately I am not really sure what the issue is here, and we generally only build this library for linux.

If you do figure out how to resolve this issue, I would be happy to review a PR though!

For now I will close this issue because it is for an version of python we don't test for.

No Worries - thanks! Will try to install solax on my RPi and see how I get on

[Darsstar]

Try downloading and then installing the .whl file instead of the .tar.gz. That way you skip having to build the wheel locally, before installing the wheel.

Hi installing the .whl file seemed to work so I ran the script on the github home page to see if the installation was OK. It seems to work but unfortunately, my inverter seems not to be supported. I will try the curl commands on the Wiki page and see if they produce any output.
