Haskell 在Osx 10.15.3上安装ghc mod失败（已尝试lts-8.24）

我是haskell的新手，希望在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。行动失败了。如果有人能帮助我，我将不胜感激！ 错误日志如下所示：

如果您只是想让haskell处理vscode，那么我发现ghcide工作得非常好

将其签出到本地目录，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

e、 g.更改此行：

分解器：夜间-2019-09-21

致：

分解器：lts-14.12

然后使用：（记下可执行文件的放置位置）

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
