Mistaken local::lib Module Installation

Likeless has asked for the wisdom of the Perl Monks concerning the following question:

By mistake, I have installed a number of CPAN modules in /root. I did this by misconfiguring CPAN setup and accidentally picking local::lib as the option.

It doesn't work to have the modules located within /root as I need them to be accessible to all users.

I have read the documentation of local::lib, but I am struggling to understand it all.

My questions, then are:

Can I just change my local::lib setting in CPAN for root, install the modules in somewhere like /usr/local and go from there? If I adjust my path and @INC variables to use the modules installed in /usr/local, will it be as though the modules installed in /root do not exist?
Would it be safe to simply delete the directory /root/perl5?

Would it be safe to simply delete the directory /root/perl5? Yes ...local::lib... local::lib is when you want to install stuff in your home directory, when you're NOT root	[reply]

•Would it be safe to simply delete the directory /root/perl5? Not if it's being used by the operating system. (Is it ?) Cheers, Rob	[reply]

How would I know? /root/perl5 was created by CPAN when I ran it with local::lib by accident, as described. It didn't exist before. There are other modules installed through the OS package manager (yum) and they are installed in other locations.	[reply]

if cpan/local::lib created that directory, it is safe to delete it :) If you type `perl -V` and you'll see a bunch of stuff that ends like `%ENV: PERL5LIB="/root/perl5/lib/perl5" @INC: /root/perl5/lib/perl5 /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .` [download] local::lib overrides comes from %ENV vars like PERL5LIB , all the other ones come from Config or are compiled in, to get a list run <c> perl "-V:install.*" </c. Stuff from %ENV , once removed from %ENV, its as if it doesn't exist, so you can delete those dirs if you want	[reply] [d/l] [select]

It didn't exist before Then it's safe to remove. Sorry - in your original post I missed the implication that the directory did not previously exist. (I still don't see it there, though Anonymous apparently worked it out ;-) Cheers, Rob	[reply]
