Question

I’m trying to install some libraries using Perl from the command line:

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

However, I’m not being able to:

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

In fact, I haven’t been able to install any library (YAML for example). I also tried someone’s suggestion:

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

However I had the same outcome. Could someone please help me to figure out how to install those packages? I’m running Perl in a Windows 7 machine.

Answer 1

Fix earlier errors first! XML::Tidy has a stated dependency on Test::Pod::Coverage and XML::XPath. You don’t have them installed, so an error must have occurred earlier in the installation process.
