HaskellQuickCheck-2.11.3 包中缺少文件

Question

我尝试了运行我的程序，该程序通过 ghc MyProgramm.hs 使用 Haskell QuickCheck，但收到以下错误：

$ ghc Ex2.hs 
[1 of 1] Compiling Ex2              ( Ex2.hs, Ex2.o )

Ex2.hs:21:1: error:
    Could not find module ‘Test.QuickCheck’
    There are files missing in the ‘QuickCheck-2.11.3’ package,
    try running 'ghc-pkg check'.
    Use -v to see a list of the files searched for.

21 | import Test.QuickCheck (
   | ^^^^^^^^^^^^^^^^^^^^^^^^...

我安装了 stack、运行、stack update 和 stack install QuickCheck 没有问题，但错误仍然存在。然后，我运行 cabal install QuickCheck 得到以下错误：

$ cabal install QuickCheck

cabal: Error: some packages failed to install:
QuickCheck-2.12.4-3d2YDDqfPBn4BfmTJbpJXK failed during the building phase. The
exception was:
ExitFailure 1

但是，我已经安装了 arch 软件包 haskell-random、haskell-tf-random 和 haskell-mwc-random。有人知道如何解决这个问题吗？

编辑：我也运行 cabal install random --reinstall.

Answer 1

尽管我有一个 main = do 并且无法以这种方式工作，但我能够运行我的 QuickCheck 测试如下：

为了运行快速检查，首先加载您的程序：

 $ ghci MyProg.hs

然后到运行 quickCheck，找到你要的测试运行，然后运行它用：

 $ quickCheck my_quick_check
