You can also create a "Bundle" file using the autobundle command of the cpan client to list all modules for later reinstallation:

cpan -a

...
Package namespace         installed    latest  in CPAN file           
+                                                       
Algorithm::C3                  0.10      0.11  HAARG/Algorithm-C3-0.11
+.tar.gz                                                
Algorithm::Diff              1.1903     1.201  RJBS/Algorithm-Diff-1.2
+01.tar.gz                                              
...

Wrote bundle file
    /home/corion/.local/share/.cpan/Bundle/Snapshot_2021_07_05_00.pm

[download]

The list of modules listed in this bundle can then be installed in another environment using:

perl -MCPAN -e 'install Bundle::Snapshot_2021_07_05_00'

[download]

(as the module itself says)
