我正在使用堆栈来组织我的Haskell项目，如下所示：
.
├── ProjectA
│ ├── Main.hs
│ ├── ProjectA.cabal
│ └── Setup.hs
├── ProjectB
│ ├── Main.hs
│ ├── ProjectB.cabal
│ └── Setup.hs
├── ProjectC
│ ├── Main.hs
│ ├── ProjectC.cabal
│ └── Setup.hs
└── stack.yaml
也就是说，我有很多目录，每个目录都包含一个包，还有一个包含这些目录的堆栈环境。在我的工作流程中，我使用stack build来获取编译错误并指导我的工作。问题是，给我正确的错误消息需要花费太长时间，并且它会重建我编辑的每个文件的每个依赖项。我喜欢以交互方式工作 - 也就是说，我编辑几行代码，编译，重复 - 总是一次只编辑一个文件。这大大减缓了我的工作流程。
在使用stack（使用全局安装）之前，我只会在我正在编辑的文件上运行GHCI，但是that doesn't work anymore。有没有办法加速在我的设置上收到错误消息？
这是stack build --verbose：
