如何在mac上安装haskell Parallel？ 我正在尝试：'$ sudo cabal install parallel'但它不起作用。我收到以下消息：
Resolving dependencies...
Configuring parallel-3.2.0.0...
Preprocessing library parallel-3.2.0.0...
Building parallel-3.2.0.0...
<command line>: cannot satisfy -package-id deepseq-1.1.0.2-09b3aed0c4982bbc6569c668100876fa
(use -v for more information)
cabal: Error: some packages failed to install:
parallel-3.2.0.0 failed during the building phase. The exception was:
ExitFailure 1
感谢。
