linux - Haskell Yesod 问题

Question

有人可以帮助我吗？!我在 C9 工作区的 Haskell Yesod 大学网站上工作，我已经通过命令 Yesod 安装并更新 cabal，但是当我尝试“堆栈构建”命令时，出现了这个悲惨的错误消息:

 $ stack build

aulahaskell-0.0.0: build (lib + exe)
Preprocessing library aulahaskell-0.0.0...
[ 7 of 13] Compiling Handler.Cliente  ( src/Handler/Cliente.hs, .stack-work/dist/x86_64-linux/Cabal-1.24.2.0/build/Handler/Cliente.o )

/home/ubuntu/workspace/web2017/src/Handler/Cliente.hs:10:1: error:
    Failed to load interface for ‘Network.HTTP.Types.Status’
    It is a member of the hidden package ‘http-types-0.9.1’.
    Perhaps you need to add ‘http-types’ to the build-depends in your .cabal file.
    Use -v to see a list of the files searched for.

    Process exited with code: ExitFailure 1

说真的，我尝试了很多方法来修复它，但没有任何效果 =S

仔细阅读错误信息:

Failed to load interface for ‘Network.HTTP.Types.Status’
It is a member of the hidden package ‘http-types-0.9.1’.
Perhaps you need to add ‘http-types’ to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.

行 Perhaps you need to add 'http-types' to the build-depends in your .cabal file 告诉你该怎么做:你必须添加 http-types 到您的 cabal 文件中 aulahaskell 库的 build-depends: 部分。

如果这没有帮助，请发布您的 cabal 文件。
