Esp-idf installation is failing in Windows

[SergioGasquez]

Hi! I think esp-idf installation is failing for Windows, I discovered the issue while working in espup, at first I thought I was doing something wrong (as it's my first from-scratch Rust project) but I managed to reproduce it with esp-idf-sys via esp-idf-template. Steps to reproduce:

1. Generate an esp-idf-template project: In my case I generated for esp32 with std and v.4.4
2. Export $Env:LIBCLANG_PATH="<path_to_esp>/.espressif/tools/xtensa-esp32-elf-clang/lib"
3. Build the project. At this point, esp-idf-sys should download and install esp-idf under the .embuild directory. The build fails with:

 ERROR: Could not find a version that satisfies the requirement windows-curses; sys_platform == "win32" (from esp-windows-curses) (from versions: none)
  ERROR: No matching distribution found for windows-curses; sys_platform == "win32"
  Traceback (most recent call last):

  Error: Could not install esp-idf

  Caused by:

Again, I am no expert in embuild/esp-idf-sys and even less, in Windows, so let me know if I'm missing something.

After some more testing, I found out that the error comes from the Window install script. Both install.bat and ìnstall.ps1 are giving me the same error

[SergioGasquez]

Mistery solved, I was using python Python 3.11.0b5 which is a pre-release and there are no wheels for windows-curses for python 3.11. Running the installers with python 3.8.7 works fine. Now, the question is.... Should any check be done in embuild to avoid this situation?

[SergioGasquez]

Nevermind, browsing through embuild code I found out that there is already a TODO and a python version check, should we keep this issue open to address this todo and add a check to see that the version is lower than 3.11 ?
