我是haskell的新手,想在vs代码上部署haskell。当我尝试使用“stack install ghc-mod --resolver lts-8.24”安装 ghc-mod 时。动作失败。如果有人可以帮助我,将不胜感激!错误日志如下:

如果你只是想让 haskell 在 vscode 上工作,那么我发现 ghcide 工作得很好。

https://github.com/digital-asset/ghcide

将其检出到本地目录,并修改它附带的 stack.yaml,使其具有与您要使用的项目相同的解析器。

例如改变这一行:

解析器:nightly-2019-09-21

至:

解析器:lts-14.12

然后使用安装它:(记下它放置可执行文件的位置)

堆栈安装

最后,打开 vscode 并添加 ghcide 扩展并将其指向配置中的 ghcide 可执行文件。
