What's Wrong?

Running Claude Code CLI v2.1.146 in WSL2 (Debian 12) on latest stable Windows 11. Recently Claude started getting errors while attempting to run basic linux (bash) commands. It forces me to run such commands manually, then copy paste the output. It's tedious and annoying.

I've searched online and tried a few fixes that seem to make sense. The problem seems to be Windows path entries with parenthesis in $PATH, yet even with my attempts and fixing this in my ~/.bashrc Claude believes the problem is due to the harness shell snapshot not applying my new shell fixes. When I ask claude to check if it's fixed, it replies "Still getting PATH errors with Windows paths containing parentheses (like "Program Files (x86)"). This is a Claude Code harness shell snapshot issue I can't work around."

What Should Happen?

It should be able to run basic commands in WSL
