Windows Store Python causes crash on start #2293

Open tonybaloney opened 2 years ago

What were you trying to do?

Launch from a virtual environment

What steps did you take to trigger the issue?

  1. Install Python 3.8 from the Windows store
  2. Create a virtual environment
  3. Start mu

mu.config.DATA_DIR will be C:\Users\<user>\AppData\Local\python\mu

But, this an app execution alias, so the path is actually something like:

C:\\Users\\<user>\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\\LocalCache\\Local\\python\\mu\\

This only causes an issue when launching a subprocess, like when mu will create virtual environments, because Windows cannot apply the alias redirect to the subprocess.

Operating System Version

Windows 11

Mu Version

main (1.1.1)

I also needed to do this to get mu-editor running with windows store python (apart from applying the patch) https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd#enable-long-paths-in-windows-10-version-1607-and-later
