进程退出，代码为：ExitFailure 1" after build project Haskell

Question

连接到 .cabal 文件后一些包（例如 text）和构建项目后抛出异常：Process exited with code: ExitFailure 1".

对于构建项目，我在终端中使用 haskell-stack，命令：stack build。（我使用的是 MacOS Capitan）

某行 .cabal 文件：

executable Real-exe
hs-source-dirs:      app
main-is:             Main.hs
ghc-options:         -threaded -rtsopts -with-rtsopts=-N
build-depends:       base
                 , Real
                 , text
default-language:    Haskell2010

没有（文本包）所有工作。

完整错误：

Answer 1

此类错误可能是由于包缓存已过期所致。 ghc-pkg recache 运行在命令行中可能会有帮助。

否则，执行 stack --no-system-ghc --install-ghc build 而不是通常的堆栈命令行只会告诉堆栈根本不使用已安装的库，这也可能有所帮助。
