Windows python3/pip3 ssl issue - cannot install litex

[fanoush]

Hello,

I have extracted recent oss-cad-suite-build to C:\oss-cad-suite, run start.bat and included python3 cannot install any package due to ssl error. This is on Window 10

[OSS CAD Suite] C:\oss-cad-suite\litex>python3 -m pip install pyserial

This also doesn't work with litex setup. As I need git for that I run Git for windows command prompt and then run environment.bat and then as per readme

https://github.com/YosysHQ/oss-cad-suite-build?tab=readme-ov-file#using-litex

the first init step works but then the setup fails on pip3 ssl issue too
