为什么使用Stack的bytestring-show包安装失败？

Question

它与cabal install bytestring-show安装得很好。这是日志：

首先，最后一行的错误是access denied所以我使用管理员访问权限执行了上述操作，并且它抱怨它无法找到指定的路径。

我将extra-deps: [bytestring-show-0.3.5.6]放入yaml文件中，并将bytestring-show作为构建依赖项添加到cabal文件中。

我也尝试升级堆栈并收到此错误：

C:\>stack upgrade

Try rerunning with --install-ghc to install the correct GHC into C:\Users\Marko\AppData\Local\Programs\stack\x86_64-windows\

我昨天刚刚安装了Haskell平台，但我已经安装了几个月前的早期版本，所以也许它没有得到正确的清理。

我不知道该怎么做。
