hie-8.4.3: user error (Failed to find requested hint files:

/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

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

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

[lukel97]

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

[alanz]

TODO: update README

[jarcane]

I am having this same problem. It complains about the missing hlint file, and if I do the workaround @bubba suggests I get a similar error to @leshow :

[alanz]

@jarcane the current version of hie is 0.6.0.0, and it did update hlint.

Please re-install and try again.

[LinArcX]

Still same issue with arch linux and install bunch of packages like hoogle, hlint. but still complain about hlint.yaml. I follow @owickstrom and @bubba . but nothing changed.

[leshow]

@LinArcX don't install any other packages from AUR, afaik hie provides its own versions of the required packages

[LinArcX]

@leshow:
I installed hie binary version from archlinuxcn.
archlinuxcn/repo#1044
And stack binary version. (without installing ghc and it's whole bunch of libraries)
archlinuxcn/repo#882
Is it OK?

hie-8.6.3: user error (Failed to find requested hint files:
  /usr/bin/data/hlint.yaml
)

This is one of the issues we're having with generating our own static binaries: hlint relies on data-files which currently there's not a great way of bundling with a binary, and similarly for cabal-helper
For now though touch /usr/bin/data/hlint.yaml should fix it 😬

[LinArcX]

@bubba nothing changed.

[fendor]

This should be different now, hie does no longer choke on that, however, hlint does not work if there is no hlint.yaml, or in general, when its data-files are missing. The issue #1143 aims to solve this problem as a whole, once we have decision for it.

[jneira]

Closed by #1143: hlint data files could be placed in a subfolder data in the same directory where the hie executable is. We'll enforce that in the release artifacts.

Only left update docs.
