Problems with no default Python #335

Closed henryiii closed 8 months ago

henryiii commented 2 years ago

The theme isn't happy if there's no default python (like on macOS in my case):

fish: Unknown command: python
~/.config/fish/functions/fish_prompt.fish (line 1):

For some reason, this only happens in the VSCode terminal; other terminals are fine. I'm guessing this could be switching based on an envvar or something VSCode sets and not on whether python is available? A little extra protection for the existence of the python command would be nice. Also, python is required to be available via PEP 394, only python3 is required.

FYI, I also have pyenv installed, which loves to break things by adding shims, but I don't think that's visible or causing a problem here. PPS: I think vscode is getting tripped up on conda, possibly. It does seem to happen only if I start vscode from a shell with a conda environment activated. Either way, it's still shouldn't make the terminal dump a page of text trying to print the prompt if python is missing. :)
