Updating to ARTIQ 9 giving errors

Flash77

After seeing ARTIQ 9 release, I re-flashed the FPGA with new firmware and then updated to the latest version using pacman -Syu command in MSYS2. But now I can no longer connect to the machine or even run a simple artiq_run command

 artiq_run

    from pythonparser import diagnostic
ModuleNotFoundError: No module named 'pythonparser'

Trying to print the log doesn't work either

Flash77 It seems that there is a mismatch between the python versions in Artiq 9 and you local PC. Artiq 9 uses Python 3.12 via nixos-25.11. When you used pacman -Syu command to update, it might have updated python, which could cause incompatibility.

Flash77 ModuleNotFoundError: No module named 'pythonparser'

Please run pacman -Q to check if pythonparser is installed. Then use pacman -Ql to list its files and check that they are in the correct folders.

This has absolutely nothing to do with NixOS and the MSYS2 packages for ARTIQ-9 are built with Python 3.14 (reference: https://git.m-labs.hk/M-Labs/artiq-extrapkg/src/branch/release-9/msys2/msys2_packages.nix#L201)
