Question

我尝试安装cabal-doctest-1，但是我收到了这样的编译错误：

Resolving dependencies...

cabal: Leaving directory '.'
cabal: Error: some packages failed to install:
cabal-doctest-1.0.1 failed during the building phase. The exception was:
ExitFailure 1

我尝试将FlexibleContexts硬编码到.hs文件中，但它没有帮助。我有Cabal 1.24。

编辑：

我更新到GHC 8.0.2，安装了cabal-doctest-1，但是lnker似乎没有找到它。此外，我无法将DocTest导入任何模块（您可以在下面找到搜索到的位置）。这是链接器错误：

提前致谢

无法安装cabal-doctest-1，导致编译错误
