Windows中現有沙箱上的Cabal安裝失敗

Question

我已經在Windows上安裝了Haskell平台。 我試圖從現有的陰謀集團沙箱中建立一個現有的項目。 每當我嘗試重新安裝時，所有軟件包都會失敗，並顯示以下錯誤：

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

想知道我需要在哪里指定絕對方向。 Cabal安裝在這里：注意：我正在使用Powershell執行這些命令。

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

這是完整的輸出。

websockets-snap-0.8.2.1 (new package)

cabal.exe: The following packages are likely to be broken by the reinstalls:

Use --force-reinstalls if you want to install anyway.

如何為前綴指定絕對目錄名稱？

Answer 1

您可以嘗試使用此處描述的解決方案。 基本上是關於刪除/替換powershells默認目錄別名。 但這肯定不是修復該問題的最與Powershell兼容的方法。
