Windows中现有沙箱上的Cabal安装失败

Question

我已经在Windows上安装了Haskell平台。 我试图从现有的阴谋集团沙箱中建立一个现有的项目。 每当我尝试重新安装时，所有软件包都会失败，并显示以下错误：

cabal.exe: expected an absolute directory name for --prefix:

想知道我需要在哪里指定绝对方向。 Cabal安装在这里：注意：我正在使用Powershell执行这些命令。

C:\Users\user\AppData\Roaming\cabal\bin\cabal.exe

这是完整的输出。

如何为前缀指定绝对目录名称？

Answer 1

您可以尝试使用此处描述的解决方案。 基本上是关于删除/替换powershells默认目录别名。 但这肯定不是修复该问题的最与Powershell兼容的方法。
