Cabal 将不会获得新的 haskell 包
我尝试使用 cabal 获取 wxHaskell 包 使用：
cabal install wxcore --global
cabal install wx
但是运行此命令会出现以下错误：
>cabal install wxcore --global
Resolving dependencies...
cabal: Error: some packages failed to install:
wxcore-0.11.1.2 failed during the configure step. The exception was:
sh: runGenProcess: does not exist (No such file or directory)
我做错了什么？我需要先安装哪些软件包吗？
I tried to get the wxHaskell package using cabal
using:
cabal install wxcore --global
cabal install wx
But running this gave the following error:
>cabal install wxcore --global
Resolving dependencies...
cabal: Error: some packages failed to install:
wxcore-0.11.1.2 failed during the configure step. The exception was:
sh: runGenProcess: does not exist (No such file or directory)
What did I do wrong? Is there packages I need to install first?

通过 cabal 安装 wx 是很棘手的。如果您使用的是 Windows，我建议从 http://haskell.org/haskellwiki/WxHaskell 下载其二进制包/下载
Getting wx to install through cabal is tricky. If you're using Windows I suggest downloading their binary package from http://haskell.org/haskellwiki/WxHaskell/Download
我对 Wx 不熟悉，但我希望您需要先安装底层 C 库，然后再安装依赖于它的 Haskell 包。
I'm not familiar with Wx, but I would expect that you need to install the underlying C library before installing the Haskell packages that depend on it.
是的，我认为这是来自 wx 包（及其自定义配置脚本）的（糟糕的）警告，即 wxWidgets 库不在您的系统上。
Yes, I think that is a (poor) warning from the wx package (and its custom configure script) that the wxWidgets library isn't on your system.
