Error from here

As you can see from the log above the library compiles fine, but the executable fails to (even though the base version in the build is supposed to contain the module). I cannot find a straightforward way to exclude the executable from the compilation, so I was wondering if it would be worth splitting it out in a separate package?

Also saw this, ghc v8.8.4 on windows

Hi anynews regarding this issue? We are still experiencing the same issue blocking for example installation of haskell-language-server

As a temporary workaround, there is a fork without the troublesome troubleshoot executable on https://github.com/f-f/haskell-with-utf8

Go there, clone the repository and then add its folder as an extra package in your stack.yaml file.

[CarstenKoenig]

maybe an easier fix is to add this under extra-deps in your stack.yaml:

  - github: f-f/haskell-with-utf8
    commit: 8ae743ac6503a4c494ea3bd52f1fe7d72f9f125d

no need to clone the repository yourself

Hopefully, this is fixed now! Sorry for the delay, everyone 😞.

[kirelagin]

I have uploaded v1.0.2.2 to Hackage and it includes this fix.

Thank you @kirelagin!
