I am not root, how can I install a module in a personal directory?

As of CPAN 1.9463, if you do not have permission to write the default perl
library directories, CPAN's configuration process will ask you whether
you want to bootstrap <local::lib>, which makes keeping a personal
perl library directory easy.

Another thing you should bear in mind is that the UNINST parameter can
be dangerous when you are installing into a private area because you
might accidentally remove modules that other people depend on that are
not using the private area.

How to get a package, unwrap it, and make a change before building it?

Have a look at the C<look> (!) command.

I installed a Bundle and had a couple of fails. When I
retried, everything resolved nicely. Can this be fixed to work
on first try?

The reason for this is that CPAN does not know the dependencies of all
modules when it starts out. To decide about the additional items to
install, it just uses data found in the META.yml file or the generated
Makefile. An undetected missing piece breaks the process. But it may
well be that your Bundle installs some prerequisite later than some
depending item and thus your second try is able to resolve everything.
Please note, CPAN.pm does not know the dependency tree in advance and
cannot sort the queue of things to install in a topologically correct
order. It resolves perfectly well B<if> all modules declare the
prerequisites correctly with the PREREQ_PM attribute to MakeMaker or
the C<requires> stanza of Module::Build. For bundles which fail and
you need to install often, it is recommended to sort the Bundle
definition file manually.

In our intranet, we have many modules for internal use. How
can I integrate these modules with CPAN.pm but without uploading
the modules to CPAN?

Have a look at the CPAN::Site module.

When I run CPAN's shell, I get an error message about things in my
C</etc/inputrc> (or C<~/.inputrc>) file.

These are readline issues and can only be fixed by studying readline
configuration on your architecture and adjusting the referenced file
accordingly. Please make a backup of the C</etc/inputrc> or C<~/.inputrc>
and edit them. Quite often harmless changes like uppercasing or
lowercasing some arguments solves the problem.

Some authors have strange characters in their names.

Internally CPAN.pm uses the UTF-8 charset. If your terminal is
expecting ISO-8859-1 charset, a converter can be activated by setting
term_is_latin to a true value in your config file. One way of doing so
would be

    cpan> o conf term_is_latin 1

If other charset support is needed, please file a bug report against
CPAN.pm at rt.cpan.org and describe your needs. Maybe we can extend
the support or maybe UTF-8 terminals become widely available.

Note: this config variable is deprecated and will be removed in a
future version of CPAN.pm. It will be replaced with the conventions
around the family of $LANG and $LC_* environment variables.

=item 11)

When an install fails for some reason and then I correct the error
condition and retry, CPAN.pm refuses to install the module, saying
C<Already tried without success>.

You could use the force pragma like so

  force install Foo::Bar

Or, to avoid a force install (which would install even if the tests
fail), you can force only the test and then install:

  force test Foo::Bar
  install Foo::Bar

Or you can use

  look Foo::Bar

and then C<make install> directly in the subshell.

How do I install a "DEVELOPER RELEASE" of a module?

By default, CPAN will install the latest non-developer release of a
module. If you want to install a dev release, you have to specify the
partial path starting with the author id to the tarball you wish to
install, like so:

    cpan> install KWILLIAMS/Module-Build-0.27_07.tar.gz

Note that you can use the C<ls> command to get this path listed.
