Question

我正在尝试使用需要包hsdev的pligin SublimeHaskell在macOS Sierra上的Sublime文本上设置Haskell自动完成。因此，当我尝试在ghci版本2.0.0.2上使用cabal版本8.2.1安装hsdev时，我收到以下错误 -

Building regex-pcre-builtin-0.94.4.8.8.35...
Failed to install regex-pcre-builtin-0.94.4.8.8.35

    (use -v for more information)

最后构建失败并显示消息 -

cabal: Error: some packages failed to install:
hsdev-0.2.5.1-KLZyINgHjNjLoIhf1REoIt depends on hsdev-0.2.5.1 which failed to
install.
regex-pcre-builtin-0.94.4.8.8.35-ErSIfFBjU2O890llA9JKT4 failed during the
building phase. The exception was:
ExitFailure 1

我该如何解决这个问题？

使用ExitFailure 1，cabal install hsdev失败
