在windows 7上安装Cabal-dev

Question

我正在尝试在Windows7上安装Cabal-dev。

我已经成功地克服了无法构建网络的问题，使用以下代码：

cabal install --constraint="network installed" cabal-dev 

然而，我得到了这样的结果：

>cabal install --constraint="network installed" cabal-dev

Answer 1

Mikhail Glushenkov的建议奏效了

我克隆了git repo for cabal-dev，然后像这样构建它：

runhaskell -isrc admin/bootstrap.hs

然后我补充说

{windowspath ..}\cabal-dev\cabal-dev\bin

回到我的道路上，一切都正常了。

我现在可以在我的yesod文件夹中运行cabal-dev install，让yesod最终工作。
