我想在 Mac 上使用 Atom 在 Haskell 中编程。因此,我在 Atom 中安装了以下软件包:
haskell-ghc-mod
ide-haskell
ide-haskell-cabal
language-haskell
之后我从这里安装了 Haskell 平台 8.2.1: https ://www.haskell.org/platform/#osx-none
这似乎不起作用,因为我无法编译,并且在每次启动 Atom 时都会出现以下错误消息:
Haskell-ghc-mod: ghc-mod failed to launch. It is probably missing or misconfigured. ENOENT
然后我尝试按照https://atom-haskell.github.io/installation/installing-binary-dependencies/中的描述手动安装必要的软件包,这也失败了(甚至取消注册失败):

Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.
Daniels-MacBook-Pro:ghc-mod-sandbox daniel$ cabal uninstall ghc-mod stylish-haskell
cabal: This version of 'cabal-install' does not support the 'uninstall'
operation. It will likely be implemented at some point in the future; in the
meantime you're advised to use either 'ghc-pkg unregister ghc-mod' or 'cabal
sandbox hc-pkg -- unregister ghc-mod'.
Daniels-MacBook-Pro:ghc-mod-sandbox daniel$ ghc-pkg unregister ghc-mod
ghc-pkg: cannot find package ghc-mod

我已经在 stackoverflow 中搜索了答案,但没有什么对我真正有用。谁能告诉我我错过了什么?
