Question

我有Win 10 @ x64台计算机。我安装了Haskell Platform (HP) 8.0.1，但后来意识到我需要的软件包在构建GHC 8时会遇到麻烦。所以我卸载了HP 8并安装了HP 7.10.3。 cabal目录中的config文件仍然是8-installation，所以我手动删除了它（因为来自7.10.3的cabal无法解析它。）

现在我有问题cabal-安装任何意味着构建可执行文件的包。请参阅下面的构建cheapskate的示例。在构建yaml时，我有非常相似的消息，所以我想包装本身并没有特定的内容。正如我说任何包安装可执行文件的问题。

cabal: Error: some packages failed to install:
cheapskate-0.1.0.5 failed during the building phase. The exception was:
ExitFailure 1

Answer 1

描述似乎对应于损坏的包数据库。

ghc-pkg check可以帮助查看是否是这种情况，ghc-pkg recache可能有助于解决问题。如果失败，则可以删除本地包数据库目录，该目录是ghc-pkg list列出的两个目录之一。

在cabal-install（Haskell平台）期间ld.exe无法找到库
