Hi,

When building HIE with cabal, I received the following error message:

[1 of 1] Compiling Main             ( Main.hs, C:\work\dev\haskell-ide-engine\dist-newstyle\build\x86_64-windows\ghc-8.10.1\fake-package-0\x\script\build\script\script-tmp\Main.o )

CallStack (from HasCallStack):
  error, called at src\Env.hs:75:3 in hie-install-0.8.1.0-inplace:Env

The command I used to build HIE is:

 .\cabal-hie-install.cmd hie

Environment:

Windows 10 64-bit,
ghc 8.10.1 (installed with choco),
cabal 3.2.0.0,
HIE master commit d9d21fb0675280e20e837dbeb5715dab65e9c6be (HEAD -> master, tag: 1.4, origin/master, origin/HEAD).

Thank you for your bug report! This seems to be a duplicate of https://github.com/haskell/haskell-ide-engine/issues/1646

Essentially, you have ghc-8.10.1 but HIE doesnt support ghc-8.10.1. The message is just wrong and it is generated because we filter all available ghc by supported ghc versions.
