Re^4: Protocol scheme 'http' is not supported

in thread Protocol scheme 'http' is not supported

I'm happy for anybody else's thoughts since mine don't seem to be liking me much at the moment ;)

When this all started I did have to install WWW:Mechanize in order to get the ball rolling. I don't recall any errors at the end of it but that may have been because I was figuring that it'd just magically work afterwards...

I think all of this comes down to a botched install of LWP::UserAgent, which should include LWP::Protocol::http. Maybe explicitly installing LWP::Protocol or LWP::Protocol::http can get the situation unstuck, but I wonder how the other modules can pass their test suites when the most basic prerequisites are missing.

Maybe you are mixing two versions of Perl, and have half of the module installed on one version and half on the other? Mixing Perl module directories seems like it's always a recipe for bad interactions to me...

[Bloodnok]

Indeed Corion, hence my comment/guess.

[Anonymous Monk]

Corion/Bloodnok, Yeah, It seemed like it's all about modules gone wild. I've got the exact same code (not what I posted; I boiled it down to the fewest number of lines that still showed the problem) and version of Perl on a Windows machine with no problems there so I figured moving it over to Linux would be a breeze.

I'll try forcing an install of LWP::UserAgent, LWP::Protocol, and/or LWP::Protocol::http and see what that does for me. Is there a way from inside of cpan (ie the "perl -MCPAN -e shell") to actually uninstall an existing module or is it a manual cd-to-the-directory-and-rename sort of thing...?

Many thanks, Greg
