我知道它缺少依赖项，但我认为CPAN会自动安装所有依赖模块。这是错误：

然后我尝试单独安装一个依赖模块：
cpan[2]> install PadWalker
Running install for module 'PadWalker'
Running make for R/RO/ROBIN/PadWalker-1.96.tar.gz
Has already been unwrapped into directory /root/.cpan/build/PadWalker-1.96-n6C9km
Could not make: Unknown error
Running make test
Can't test without successful make
Running make install
Make had returned bad status, install seems impossible
有人能指出我正确的方向吗？我是root用户，截至目前，它是Ubuntu 12.04.1。

可以使用CPAN安装Scrappy。在我的情况下，只有 Moose 必须被强制（失败的1/382测试程序.0 / 18150子测试失败）。

您应该尝试手动安装 PadWalker 以找出Could not make: Unknown error背后的原因。
在我的情况下， PadWalker 可以从~/.cpan/build/PadWalker-1.96-XW0Mq2安装，如下所示：
