【问题描述】：
我的 ghc 安装已过期，因此我决定重新安装 ghc 和 cabal 以希望能解决一些问题。我开始遵循here 的步骤。 GHC 现在是 7.8.3 版。
然后我删除了 ~/.cabal 并尝试使用这些步骤进行安装，但它失败了。所以我再次删除了 .cabal 并尝试了here 的步骤，但是当我运行sh bootstrap.sh 时，它会遇到缺少的模块：

Error during cabal-install bootstrap:
Building the parsec package failed.
当我运行 ghc-pkg check 时，我会得到很多这样的东西：
cannot find any of ["libHSOpenGLRaw-1.5.0.0.a","libHSOpenGLRaw-1.5.0.0.p_a","libHSOpenGLRaw-1.5.0.0-ghc7.8.3.so","libHSOpenGLRaw-1.5.0.0-ghc7.8.3.dylib","HSOpenGLRaw-1.5.0.0-ghc7.8.3.dll"] on library path

Warning: haddock-html: /usr/local/share/doc/x86_64-linux-ghc-7.8.3/Cabal-1.21.1.0/html doesn't exist or isn't a directory
然后是这个：

【问题讨论】：
-
如果按照建议运行
ghc-pkg check会发生什么？ -
@GaneshSittampalam 用 ghc-pkg 检查输出更新了问题
-
首先清除 ghc 包。无论如何，在沙盒中工作是最可靠的方式，全局包往往会破坏很多。
