No ghc installations found in $PATH.
The script requires at least one ghc in $PATH to be able to build hie.

CallStack (from HasCallStack):
  error, called at src\Env.hs:79:3 in hie-install-0.8.0.0-inplace:Env

Happens on windows when using choco install haskell-dev. Then by default, ghc 8.8.1 is installed which we do not support (I dont know why though, was there a big bug in it)? However, this error message is not useful since I compiled and ran the install script but now it is telling me that there is no ghc on the path.

コントリビューターガイド

技術スタック: なし
領域: tooling
Issue 種別: bug
難度: 2
推定時間: under 1 hour
活動状況: stale
明確さ: mostly clear
前提条件: Basic HaskellWindows command lineUnderstanding of PATH variable
初心者向け度: 45
調査方針: Investigate the GHC detection logic in Env.hs, specifically the function that checks for GHC in $PATH. Understand how the script handles Windows paths and chocolatey installations. The error message should be improved to guide users to ensure GHC is in PATH or to mention the unsupported GHC version 8.8.1. Review the relevant code at src/Env.hs around line 79 and consider enhancing the error message with actionable advice.
