我正在尝试安装 GHCJS。当我跑步时cabal install ghcjs-dom，它告诉我
Cannot find gtk2hsC2hs
Please install `gtk2hs-buildtools` first and check that the install directory is in your PATH (e.g. HOME/.cabal/bin).
好的，那我们就开始吧……
~/Haskell/ghcjs-test/domTest: cabal install gtk2hs-buildtools

cabal: Error: some packages failed to install:
gtk2hs-buildtools-0.13.0.5 failed during the building phase. The exception
was:
ExitFailure 1
在这种情况下，弄乱这些有类型错误的源文件真的是明智之举，还是有更好的方法来解决这个问题？
