"deinistall" DateTime

[dhofmeister]

so that didn't go well...i was trying to install DateTime on my HPUX system. Here's the tail-end of the dialog:

Result: FAIL
Failed 43/95 test programs. 3/3 subtests failed.
  DROLSKY/DateTime-0.77.tar.gz

Unfortunately, cpanp wasn't able to uninstall it:

CPAN Terminal> u DateTime

[MSG] No '/.cpanplus/custom-sources' dir, skipping custom sources
[MSG] No '/.cpanplus/custom-sources' dir, skipping custom sources
[MSG] No '/.cpanplus/custom-sources' dir, skipping custom sources

This will uninstall the following modules:
    DateTime

Note that if you installed them via a package manager, you probably
should use the same package manager to uninstall them

                                                                      
+                                                              
Are you sure you want to continue? [y/N]: y
Uninstalling 'DateTime'
[ERROR] Module 'DateTime' is not installed, so cannot uninstall

Any thoughts about what to do? I'd like to get rid of it so that no one thinks it is actually installed (Find::File shows it).

You tried to install DateTime, but some test failed, so it wasn't installed. No need to uninstall it.

yes, i know it didn't install. however when i run my nifty script to see what modules are installed (like i said before it's based on File::Find) it looks like it is installed:


what_perl_modules |grep -i date
/usr/local/lib/perl5/5.10.1/CPANPLUS/Selfupdate.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Attribute/Params/Vali
+date.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Params/ValidatePP.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Params/Validate.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Params/ValidateXS.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Params/Validate/XS.pm
/usr/local/lib/perl5/site_perl/5.10.1/PA-RISC2.0/Params/Validate/PP.pm

is it enough to just purge files?

[runrig]

If you want to uninstall all of the dependencies that got installed when you tried to install DateTime, then yes, you just delete the files that were installed. Just be careful not to delete anything that existed before you tried to install the library.

Though IMO, I don't think it hurts to have a few extra libraries installed (unless you're talking Switch).

it looks like it is installed:

No it doesn't, look again, Params::Validate is not DateTime

While it's "too late now", I haven't seen mentioned a technique that I hear people using all the time, and which might be useful to you in the future: Put the lib/ path where you're installing modules under version control. Just don't forget to commit between each install.
