使用CPAN Perl安装包

Question

我正在尝试从命令行使用Perl安装一些库：

perl -MCPAN -e "install XML::Tidy"

但是，我不能：

  make test had returned bad status, won't install without force

事实上，我还不能安装任何库(例如YAML)。我也尝试了别人的建议：

perl -MCPAN -e "CPAN::Shell->force(qw(XML::Tidy));"

然而，我得到了同样的结果。有没有人能帮我弄清楚如何安装这些包？我在一台Windows 7机器上运行Perl。

先修正前面的错误！XML::Tidy对Test::Pod::Coverage和XML::XPath有明确的依赖关系。您没有安装它们，因此在安装过程中之前一定发生了错误。
