在Windows上安装Haskell，cabal配置 [英] Installing Haskell on Windows, cabal config

问题描述

我根据 https://www.haskell.org/上的说明在Windows上安装Haskell。平台/ ，看第3步，它说，修改你的cabal配置文件（你可以通过运行cabal user-config init来验证位置）包含以下行：

I'm installing Haskell on Windows based on the instructions at https://www.haskell.org/platform/ and looking at step 3, it says, Modify your cabal config file (you can verify the location by running "cabal user-config init") to contain the following lines:

extra-prog-path: C:\Program Files\Haskell Platform\8.0.2\msys\usr\bin
extra-lib-dirs: C:\Program Files\Haskell Platform\8.0.2\mingw\lib
extra-include-dirs: C:\Program Files\Haskell Platform\8.0.2\mingw\include

但是自动生成的配置文件包含例如

But the auto generated config file contains e.g.

extra-prog-path: C:\Users\w\AppData\Roaming\cabal\bin

所以对于一个建议的变量来说这是一个不同的值。

So that's a different value for one of the suggested variables.

这是故意的吗？

我应该怎么做，将第3步中的行粘贴到文件的开头，文件的结尾，覆盖现有的行或者完全跳过第3步？

What should I do, paste the lines from step 3 at the start of the file, the end of the file, overwrite the existing lines or skip step 3 altogether?

推荐答案

您不需要覆盖现有的行。你可以有多个 extra-prog-path 条目，它们都可以使用。

You don't need to overwrite existing lines. You can have multiple extra-prog-path entries and they all get used.
