Hello,

I have been running through the process of setting up the development environment in windows as described in the docs, but cant seem to setup the venv in msys2.

$ source venv
Are we on Macos with Homebrew installed? No
Are we on MSys (Windows)? Yes
Checking: python3 --version
Checking: pkg-config --print-errors --exists gobject-introspection-1.0 >= 1.46.0

Hi @dave-cran, I noticed that you are running your shell from C:/msys64, but then the sys paths are all D:\a\_temp\msys2\msys64. Do you know why that is?

Not sure why. I suspect this switch happens after:

@dave-cran I think it is also a workaround to have poetry not manage your virtualenv by setting:

poetry config virtualenvs.create false
