Installation fails on Python 3.10/Windows

Cool library! Didn't install easily, though, on WIndows 10 and with Python 3.10:

    ----------------------------------------

Cloning the repo, patching pytermgui.ansi_interface.screen_size to return 0, 0 for errorno in (9, 25) instead of just 25 allowed me to install it, and then seemed to work fine! I'm no terminal expert, but I guess there's no interactive terminal available to pip's install targets.

That's one very odd issue! I assume its something to do with terminal size functionality not quite working on Windows, so I will look into it later! Thank you.

@alexlawriewood

So the commit automatically closed this issue, but as a sanity check could you test if it actually did?

Thanks for your help!

[alexlawriewood]

Yup, installs properly now! And MarkApp seems to work, as a basic test.

That's great to hear! I wonder if there is any way to replace SIGWINCH, as it allows for some neat features.
