There is definitely something wrong with how paths are handled. I managed to [solve it in the launcher](https://forum.cursor.com/t/installing-command-line-launcher-on-linux/7151/6), but today I hit the issue with python too and I am a bit afraid much more things got broken, waiting to be discovered. ---

Running \`cursor .\` also ends me up in the AppImage's virtual directory after putting cursor into \`/opt/cursor\` and adding that to PATH with my usual \`~/.bashrc\` alias. This did not occour prior to updating to 0.46.0: > > Here's that portion of \`~/.bashrc\`: > > \`\`\`bash > cursor() { > # Run the cursor command and suppress background process output completely > (nohup /opt/cursor/cursor.AppImage --no-sandbox "$@" \>/dev/null 2\>&1 &) > } > \`\`\` > > I use the usual \`nohup\` trick to avoid the AppImage forking itself into the foreground/taking over the terminal process. Again, nothings changed, and this worked before the update. export “PYTHONHOME=” you can also add it to your launch config ```auto { "configurations": [ { ... "env": { ... "PYTHONHOME": "" } } ] } ``` ---

For me the only workaround that worked was downgrading. [This comment](https://github.com/getcursor/cursor/issues/2734#issuecomment-2677163664) has a link to the 0.45.14 appimage which fixes it ---

In Linux, I managed to fix this by rolling back to version 0.45.14 (I had the same issues even with 0.45.15, not only 0.46). I also used the script kindly provided by @Kirai and made a few modifications to make it work in Wayland (added the `--ozone-platform=wayland` option). For details see [Installing command line launcher on Linux - #6 by Kirai](https://forum.cursor.com/t/installing-command-line-launcher-on-linux/7151/6) For Version Download Links see [GitHub - oslook/cursor-ai-downloads: all cursor ai version download links, and some older versions offer a better user experience](https://github.com/oslook/cursor-ai-downloads?tab=readme-ov-file) ---

So any response from the cursor team to fix this in future versions or are we all going to be stuck on version 0.45.x? ---

This bugs also effects all my extensions for linting, which makes the IDE unusable for me right now. Ruff or Pylint throw errors like ```python Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings' ``` ---

I worked on this for hours and somehow found a work around for me. It’s happening because Cursor is forcing its own Python environment. **I simply added this to the bottom of my ~/.bashrc and restarted Cursor:** ```auto export PYTHONHOME="" export PYTHONPATH="" ``` After doing that it worked with no errors, including showing proper linting. _ **How I figured it out:** _ When I unset the values manually in the terminal (in cursor), I could then run the file: ```auto unset PYTHONHOME unset PYTHONPATH python3 main.py (or clicking the run button) ``` However, if I restarted Cursor or opened a new terminal and tried running the file again, it would show the same error: ```auto Python path configuration: PYTHONHOME = '/tmp/.mount_CursorXomwZv/usr/' PYTHONPATH = '/tmp/.mount_CursorXomwZv/usr/share/pyshared/:' program name = 'python3' isolated = 0 environment = 1 user site = 1 import site = 1 Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding Python runtime state: core initialized ModuleNotFoundError: No module named 'encodings' Current thread 0x000073646c2c9740 (most recent call first): ``` So instead of having to unset the two values manually every time I ran my .py file, I just made it permanent by forcing those values to be unset by adding it to my ~/.bashrc and wallah! Hope this helps someone! ![image](https://us1.discourse-cdn.com/cursor1/original/3X/c/f/cf7a378890fa784061646e743683c914cfa2f8e0.png) ---
