如何导入/安装这些模块？谢谢。

ghc-pkg list的输出

remote add new_origin git@github-company:RiyaKapuria/ReduxForm.git

这是.cabal文件，我从这个github链接下载了这个项目，试图理解它

我尝试构建软件包，但它需要llvm-3.9才能正常工作，由于某种原因，我的设置中没有。

包hecc也被弃用了 - git repo已经4年了，已经过时了。如果你将它用于生产目的，我强烈反对你这样做。

这可能是stack.yaml，但hF2 + llvm仍然像我之前所说的一样烦扰我。

`stack.yaml`

resolver: nightly-2017-10-28
packages:
- .
extra-deps:
- hF2-0.2
- hecc-0.4.1.1
flags: {}
extra-package-dbs: []

尝试使用stack build

进行构建

在Haskell中导入加密模块
