cpanm fails to install module; gives usage message

Question

tyler@tyler:~$ cpanm −−local−lib HTML::Parser
Usage: cpanm [options] Module [...]

Try `cpanm --help` or `man cpanm` for more options.

Why is it giving me a usage message? I copy-pasted that command straight from Intermediate Perl (page 23). local::lib is installed.

This one, however, does work: cpanm -L extlib Plack

EDIT

Replacing --local-lib with -l or -L doesn't work.

Answer 1

The --local-lib option needs to take a parameter, just like you are doing in your second example: -L extlib

You probably want -l ~/p5libs or something of that nature, depending on where you want your libraries installed. The default directory that local::lib uses is ~/perl5, so it's not a bad idea to use that. :)
