尝试happstack教程时遇到的问题
提问于 2010-02-11 08:32:29
我一直在读关于Happstack的文章，并决定试一试。我正在运行xubuntu9.10，并且在教程中找到了this page，它告诉我要在教程文件夹中执行cabal install。当我这样做的时候，我得到了以下错误：
$ cabal install
Resolving dependencies...
cabal: cannot configure Crypto-4.2.1. It requires QuickCheck >=2
For the dependency on QuickCheck >=2 there are these packages: QuickCheck-2.1,
QuickCheck-2.1.0.1, QuickCheck-2.1.0.2 and QuickCheck-2.1.0.3. However none of them are available.
QuickCheck-2.1 was excluded because happstack-util-0.4.1 requires QuickCheck <2
QuickCheck-2.1 was excluded because MissingH-1.0.3 requires QuickCheck >=1.0 && <2.0
QuickCheck-2.1.0.1 was excluded because happstack-util-0.4.1 requires QuickCheck <2
QuickCheck-2.1.0.1 was excluded because MissingH-1.0.3 requires QuickCheck >=1.0 && <2.0
QuickCheck-2.1.0.2 was excluded because happstack-util-0.4.1 requires QuickCheck <2
QuickCheck-2.1.0.2 was excluded because MissingH-1.0.3 requires QuickCheck >=1.0 && <2.0
QuickCheck-2.1.0.3 was excluded because happstack-util-0.4.1 requires QuickCheck <2
QuickCheck-2.1.0.3 was excluded because MissingH-1.0.3 requires QuickCheck >=1.0 && <2.0这是不是告诉我一些包需要<2，而其他包需要>=2？
我试图通过apt-get安装1和2，但不起作用。我得到了同样的错误。如果有人能提供建议，我将不胜感激。

happstack的作者正在发送一个损坏的包。正如艾菲迈特所指出的，这是一个known problem。麦克斯·博林布鲁克的信息暗示了一种变通方法。

默认情况下，Happstack 0.5不再需要任何版本的QuickCheck。如果您选择构建测试，那么它将使用QuickCheck 2。
