Current vscode-hie-wrapper fails on macOS, probably due to GUI $PATH not being set like shell $PATH

[paul-snively]

I'm working with fp-course, and have HIE checked out and built from source as of yesterday. When I try to use HIE with this project, I get the popup:

Mismatching GHC versions: Project is 8.2.2, HIE is 8.4.3 You may want to use hie-wrapper. Check the README for more information

This is probably because, having built HIE from source on the master branch with stack, everything is in ~/.local/bin, which is in my shell's $PATH thanks to a file, /etc/paths.d/local, containing /Users/psnively/.local/bin. But unfortunately, the mechanism used to build the $PATH for the shell isn't used by the launcher system for GUI applications, so I'm betting the $PATH is not appropriate for the machinery used by the extension to launch hie-wrapper, so it's effectively not being used.

If there's anything I can add to help track this down, please let me know.

Thanks!

Update: I should add that, in my shell:

cd ~/projects/fp-course
hie-wrapper

works perfectly:

I have the same issue with latest HIE. Also on Mac (10.13.6).

Additionally, I see messages like this:

cannot satisfy -package-id Chart-1.8.3-H06ahxc2L6nqL80IisGH8: 
    Chart-1.8.3-H06ahxc2L6nqL80IisGH8 is unusable due to missing dependencies

Repeated for all dependencies.

Same code base was working fine under previous HIE.

Same code base was working fine under previous HIE.

The transition from hie-wrapper.sh to hie-wrapper (binary) is almost certainly the culprit: the former would have its $PATH set by launching a shell; the latter doesn't (on macOS).

Just figured out a workaround by adding this to VSCode's user settings:

"languageServerHaskell.useCustomHieWrapper": true,
"languageServerHaskell.useCustomHieWrapperPath": "~/.local/bin/hie-wrapper",

Seems to work.

I had the same issue. I think it is due to VSCode plugin being not up to date with the make file in HIE, or a bug in the plugin Manual fix (that worked for me): cp ~/.local/bin/hie-wrapper ~/.local/bin/hie Explanation (to my understanding): VSCode plugin has deprecated the wrapper shell script, so now it always calls to hie and not to hie-wrapper. Since hie-wrapper is capable of figuring out which hie-<version> to use, we can have it as a "default" hie and we in fact don't need a default arbitrary hie anyway.

Apparently haskell/haskell-ide-engine#748 is the same issue

[pascalpoizat]

Not sure if it is related by in the VSC user parameters,

    "languageServerHaskell.useHieWrapper": true,

is underlined and it says "Unknown configuration setting".

I did this, which might be better than copying:

ln -s ~/.local/bin/hie-wrapper ~/.local/bin/hie

It seems the use of hie-wrapper is stable and afaik it is working without have to do any workaround .
@paul-snively @Rhywun @pascalpoizat new could you try with latest extension and hie versions?
Feel free to reopen if you continue experiencing it
