使用 ghcup 安装 GHC 时如何解决此错误？

Question

我正在尝试在运行 Ubuntu 子系统的 windows 笔记本电脑上安装带有 ghcup 的 GHC。 我不断收到同样的错误，我什至不知道出了什么问题。 以下是错误消息：

关于为什么会发生这种情况以及如何解决它的任何想法？

Answer 1

根据 ghcup 存储库上的这个问题（它引用了与您相同的错误）来判断，您使用的是不受支持的 WSL 1。 您必须升级到 WSL 2。

Answer 2

$ sudo apt-get update -y && sudo apt-get install build-essential curl libffi-dev libffi7 libgmp-dev libgmp10 libncurses-dev libncurses5 libtinfo5 -y

Answer 3

1. 打开你的主页-> 在 rifgt 侧面菜单 select “显示隐藏文件”
2. 您将能够看到.ghcup 文件夹
3. open.ghcup->缓存
4. 创建一个名为 ghcup-0.0.7.yaml 的文件
5. paste with lobalTools: ShimGen: dlUri: https://downloads.haskell.org/~ghcup/shimgen/shim-2.exe dlHash: 7c55e201f71860c5babea886007c8fa44b861abf50d1c07e5677eb0bda387a70 toolRequirements: GHC: unknown_version: Linux_Debian: unknown_versioning: distroPKGs: - build-essential - curl - libffi-dev - libffi6 - libgmp-dev - libgmp10 - libncurses-dev - libncurses5 - libtinfo5 注意：'' ">= 11": distroPKGs: - build-essential - curl - libffi-dev - libffi7 - libgmp-dev - libgmp10 - libncurses-dev - libncurses5 - libtinfo5 注意：''
