我开始阅读 Yesod 并尝试将它安装在我的 Linux Mint Maya 64 位机器上。已经安装了 haskell 平台，我刚刚使用 cabal install yesod-platform 安装了 yesod-platform 包，并且一切正常。
下一步是调用 yesod init 并响应所有问题 - 应用程序名称：test。当我调用 yesod devel 时，问题就开始了......这就是我所拥有的：
Yesod devel server. Press ENTER to quit
Resolving dependencies...
Configuring test-0.0.0...

Preprocessing library 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
我对这个问题有点迷茫 - 我做了很多相关的研究，但我没有运气......
任何人都可以帮助解决这个问题吗？
