Question

我正在尝试在Windows 7上安装Cabal-dev。

我设法通过使用以下方法解决了无法构建网络的问题：

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

然而我得到了这个：

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

Mikhail Glushenkov的建议有效

我克隆了git repo for cabal-dev，然后像这样构建它：

runhaskell -isrc admin/bootstrap.hs

然后我添加了

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

到我的路上，一切正常。

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