有人知道如何解决这个错误吗？我目前正试图在Mac上安装Haskell，使用来自 https:/www.haskell.orgghcup.
安装从下面的命令行开始。
curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
但在某一时刻，我收到了这个错误。
Build failed with NonZeroExit 77 "./configure" ["--prefix=/Users/not_root/.ghcup/ghc/8.8.3"]
Check the logs at ~/.ghcup/logs and the build directory"/var/folders/n0/g0qh09_s46ndjzmy1jctj7f00000gr/T/ghcup-iyHoc8/ghc-8.8.3" for more clues.
"ghcup --cache install" failed!

当我遇到同样的问题时，我通过运行下面的命令行来解决这个问题 xcode-select --install 在我的终端中更新macOS命令行开发工具，正如在 "在mac OS上安装hashkell"，在rhaskell上。.
