Error when tryind to build JAX in Windows

Question

I am trying to install JAX in Windows, using the steps detailed in this answer.

But I am getting an error when trying to build JAX.

Here is what I have tried to do:

I have downloaded JAX
Installed Bazel and msys2 using choco. Restarted computer.
Linked virtual environment to path

[System.Environment]::SetEnvironmentVariable("PATH", $Env:Path + ";C:\users\myuser\documents\virtualenv\", "Machine")
Openen powershell as admin
Activated virtualenv
Tried to build JAX:

(virtualenv) PS C:\users\myuser\documents\virtualenv\jax-main> py ./build/build.py
Gett he following error

Any ideas on how to get around that?

The error asks if PYTHON_BIN_PATH is pointing to the python binary and it is. This is the same path I get when running sys.executable from inside the virtualenvironment.

PYTHON_BIN_PATH='C:/users/myuser/documents/virtualenv/Scripts/python.exe' is not executable. Is it the python binary?

Error message is defining about the python path. Have you tried linking `ln -s /usr/bin/python3 /usr/bin/python` — SG_Bazel, Jun 30 '22 at 04:04
