我试图在我的mac中安装cabal-dev。完成后,我尝试运行./bin/build。得到这个错误信息。在haskell中安装依赖关系
cabal: cannot configure cabal-dev-0.9.1. It requires MonadRandom ==0.1.*, tar
==0.3.*, test-framework >=0.3 && <0.6 and test-framework-hunit >=0.2
There is no available version of MonadRandom that satisfies ==0.1.*
There is no available version of tar that satisfies ==0.3.*
There is no available version of test-framework that satisfies >=0.3 && <0.6
There is no available version of test-framework-hunit that satisfies >=0.2
这是怎么回事?我如何在Haskell中安装依赖文件? 我从Haskell platform下载并安装。
