我开始阅读Yesod,我尝试在我的
Linux Mint Maya 64位机器上安装它.

已经安装了haskell平台,我刚刚安装了yesod-platform软件包和cabal install yesod-platform,并且都运行良好.

下一步是调用yesod init并回复所有问题 – 应用程序名称：test.当我打电话给yesod devel时问题就出现了…这就是我所拥有的：

Yesod devel server. Press ENTER to quit
Resolving dependencies...
Configuring test-0.0.0...
Rebuilding application...
Building test-0.0.0...
Preprocessing library test-0.0.0...
Registering test-0.0.0...
Starting development server: runghc -package-confdist/package.conf.inplace devel.hs

devel.hs:2:1:
    Failed to load interface for `Application'
    It is not a module in the current program, or in any known package.
Exit code: ExitFailure 1

我对这个问题有点失落 – 我做了很多相关的研究,但我没有运气……

有人可以帮忙解决这个问题吗？

最佳答案 在彻底清理系统之后 – 我的意思是卸载haskell-platform,yesod-platform并删除与haskell,yesod和ghc相关的文件 – 然后为haskell-platform yesod-platform进行全新安装都非常出色.
