I'm sorry that I'm asking a question like this here, but I have absolutely no idea what is causing it, and I can't seem to find any information anywhere else. Whenever I launch fish on my computer (Intel Mac running MacOS Big Sur 11.4) I get a long error about a $PATH entry.

set: Warning: $PATH entry "/usr/local/opt/fzf/bin:/usr/local/opt/[email protected]/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/opt/[email protected]/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Apple/usr/bin:/Applications/VMware Fusion.app/Contents/Public:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Wireshark.app/Contents/MacOS" is not valid (No such file or directory)
set: Did you mean 'set PATH $PATH /usr/local/opt/[email protected]/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/opt/[email protected]/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Apple/usr/bin:/Applications/VMware Fusion.app/Contents/Public:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Wireshark.app/Contents/MacOS'?

The only problem I can think of is that Wireshark isn't installed on my computer, but I find that unlikely since it used to be but I uninstalled it a long time ago, and this error just started showing up in the last couple days.

Does anybody know the cause of this error and how I might be able to fix it?

I suspect you have recently upgraded to fish 3.3.0, which contains an issue where set PATH arg:with:colons may print a superfluous error. One of the directories in your set PATH command - perhaps in your config.fish? - does not exist.

This should be fixed in fish 3.3.1, which we hope to have released soon.

  • I just checked my fish version and it is fish 3.3.0. I also hope that 3.3.1 gets released soon since it's very annoying to have to look at this error every time I open my terminal. I figured out how to remove the path involving Wireshark at least so hopefully once it does get released this won't be an issue

  • Fish just got updated to version 3.3.1 on Homebrew so I have now updated and the issue appears to be resolved. Thank you, and I will mark your answer as correct
