该命令cabal install工作正常，cabal configure --enable-tests. 但是，当我运行cabal build -j它时，它不会编译：

这是源目录的结构：

src
├── Main.hs
├── Moodle
│   ├── Parser.hs
│   ├── Translator.hs
│   └── Types.hs
└── Test
    └── Moodle.hs

这是我的 Cabal 文件（仅相关行）：

               , Cabal

               , cabal-test-hunit
  hs-source-dirs:      src
  default-language:    Haskell2010

我按照cabal-test-hunit README中的步骤进行操作。我也想知道，是否需要两次声明依赖关系？！它不是很干燥。

编辑：它似乎找不到我的模块。但是，如果我添加MoodleLatex到build-depends另一个错误：

Building MoodleLatex-0.1.0.0...
Preprocessing executable 'moddlelat' for MoodleLatex-0.1.0.0...
Preprocessing test suite 'Moodle-Tests' for MoodleLatex-0.1.0.0...

您应该将其他模块添加到该other-modules字段。如果您使用 Stack 构建，它应该会警告您需要指定哪些模块。
