Installing module problem

WisDomSeeKer34 has asked for the wisdom of the Perl Monks concerning the following question:

I want to extract url's from an HTML on my harddrive. I want to install the module HTML:TokeParser. I think this is the module that will do the job. But then I get this message:

$ cpan HTML::TokeParser

CPAN.pm requires configuration, but most of it can be done automatical
+ly.
If you answer 'no' below, you will enter an interactive dialog for eac
+h
configuration option instead.

Would you like to configure as much as possible automatically? [yes] y
+es
Use of uninitialized value $what in concatenation (.) or string at /us
+r/share/perl/5.20/App/Cpan.pm line 565, <STDIN> line 1.

Warning: You do not have write permission for Perl library directories
+.

To install modules, you need to configure a local Perl library directo
+ry or
escalate your privileges.  CPAN can help you by bootstrapping the loca
+l::lib
module or by configuring itself to use 'sudo' (if available).  You may
+ also
resolve this problem manually if you need to customize your setup.

What approach do you want?  (Choose 'local::lib', 'sudo' or 'manual')

First question: will this module do the thing that I want it to do.

Second question: what is the best thing to do? local::lib or sudo.

Generally speaking its better in the long run to create a new Perl installation for your work, including installing libraries, and leave your system Perl alone. It's a pain to manage Perl installations and it's a pain to have to become root to work, so many people choose to install Perl without root privileges. Many people use Perlbrew which will install a new Perl version in your home directory and allow you to install libs there with no root access needed. The way forward always starts with a minimal test.	[reply]

My favorite module for extracting links is HTML::LinkExtractor. I install modules into my home directory too, using local::lib Good luck!	[reply]

Try this `sudo yum --verbose install "perl(HTML::TokeParser)"`	[reply] [d/l]

`sudo yum --verbose install "perl(HTML::TokeParser)"` What makes you think that WisDomSeeKer34's operating system uses yum to install packages? See also xkcd. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l]
