While running the Cygwin updater, I allowed it to upgrade my version of perl from 5.30 to 5.32. Now when I try to run perl scripts, I receive errors related to module locations. Here is a sample program:


#!/usr/bin/perl -w
use strict;
use WWW::Mechanize;

printf("foo\n");

Here is the output:


Can't locate WWW/Mechanize.pm in @INC (you may need to install the WWW
+::Mechanize module) (@INC contains: /home/Special_K/perl_modules /usr
+/local/lib/perl5/site_perl/5.32/x86_64-cygwin-threads /usr/local/shar

+cygwin-threads /usr/share/perl5/5.32) at ./test.pl line 3.

After searching for help I modified my code to the following: 


#!/usr/bin/perl5.30.3 -w
use strict;
use WWW::Mechanize;

printf("foo\n");

Now the output is as follows: 


Can't locate strict.pm in @INC (you may need to install the strict mod
+ule) (@INC contains: /home/Special_K/perl_modules /usr/local/lib/perl
+5/site_perl/5.30/x86_64-cygwin-threads /usr/local/share/perl5/site_pe

+/usr/share/perl5/5.30) at ./test.pl line 2.
BEGIN failed--compilation aborted at ./test.pl line 2.

I'm not sure how to fix this. How do I locate strict.pm?

Also here are some related questions:

1. If I install a new version of perl, do I need to install new copies of every module that was installed for the prior version of perl I was using?

2. If I install a new version of perl but I want some scripts to use the prior version of perl, do I need to manually edit each of those scripts to point to the old version, as I have done in my second sample code block above?
