hie-8.4.3: user error (Failed to find requested hint files:
  /usr/bin/data/hlint.yaml
)

/usr/bin/data does not exist

This error only happens on 12.x LTS, 11.9 and others work fine.

I've installed from haskell-ide-engine-git in the AUR. Does anyone else have this issue? Any ideas?

[owickstrom]

Had the same issue, but where it was looking in ~/.stack/compiler-tools for the hint file. Deleted the hie executables from the compiler-tools directory and reinstalled, which solved it for me.

[leshow]

@owickstrom I'll give that a shot thanks. Are you saying it was looking in ~/.stack/compiler-tools instead of /usr/bin/data though ?

[owickstrom]

@leshow Yeah, exactly.

[leshow]

I don't have a ~/.stack/compiler-tools, locate can't find any folder by that name either.

[leshow]

Ah okay, it appears (after removing hie) that there were a bunch of binaries still in ~/.local/bin I've just removed these, and am re-installing hie. I'll close the thread if that fixes things

[leshow]

I re-installed and have now broken all of hie. I get the same error on 12.x LTS and on 11.x or lower I get:

hie-8.2.2: Could not find $libexecdir/cabal-helper-wrapper

If you are a cabal-helper developer you can set the environment variable
`cabal_helper_libexecdir' to override $libexecdir[1]. The following will
work in the cabal-helper source tree:

    $ export cabal_helper_libexecdir=$PWD/dist/build/cabal-helper-wrapper

[1]: /var/cache/pacman/pkg/haskell-ide-engine-git19859/haskell-ide-engine-git/src/haskell-ide-engine/.stack-work/install/x86_64-linux-tinfo6/lts-11.18/8.2.2/libexec/x86_64-linux-ghc-8.2.2/cabal-helper-0.8.1.0

If you don't know what I'm talking about something went wrong with your
installation. Please report this problem here:

    https://github.com/DanielG/cabal-helper/issues

The path in /var/cache doesn't actually exist it looks like, so that's helpful

A quick workaround:

mkdir ~/.local/bin/data
touch ~/.local/bin/data/hlint.yaml

I think it's weird that hlint throws an exception when there's no global file. It could be hie messing up when its invoking it
