Asp Forum - gem cleanup problem

Tom Cloyd

3/4/2009 2:28:00 PM

I'm running Kubuntu Linux 8.10, and Rubygems 1.3.1.

I'm trying to remove a sizable number of outdated gem versions, using
the 'gem update' command. Initially, it appeared to be choking on
RedCloth. I kept getting:

~$ sudo gem cleanup
Cleaning up installed gems...
Attempting to uninstall RedCloth-4.1.1
ERROR: While executing gem ... (Gem::InstallError)
Unknown gem RedCloth = 4.1.1

My immediately previous 'gem list' had shown (among other things) -

RedCloth (4.1.9, 4.1.1)

So I tried to uninstall RedCloth completely, thinking there must be
something wrong with it (although I'd seen no indication of this
elsewhere). Rubygems reported successfully uninstalling v. 4.1.9. No
mention of 4.1.1. It still appeared in the 'gem list'.

Reissuing the command, I get this:

$ sudo gem uninstall RedCloth
ERROR: While executing gem ... (Gem::InstallError)
Unknown gem RedCloth >= 0

So I went after it manually, and just deleted the gem and associated docs.

But the problem just reappeared, with a different gem. Not a RedCloth
problem after all.

$ sudo gem cleanup
Cleaning up installed gems...
Attempting to uninstall bones-2.3.1
ERROR: While executing gem ... (Gem::InstallError)
Unknown gem bones = 2.3.1
tomc@tomc-desktop:~$

I don't understand the problem here. Can anyone offer me a clue?

Thanks!

Tom

Tom, sounds a lot like #22770:

Which seems to have a workaround detailed at the bottom of:

OK, after digesting the information you kindly directed me to, here's
what the consensus appears to be:

1. the "gem clean" command is broken, at least some of the time. For me,
in my environment, all the time.
2. the "workaround" is to uninstall each gem and reinstall it. With
about 25 gems installed, that definitely a delightful prospect. It's
even worse when one considers that, as I documented in my original
email, the 'gem uninstall' command is also broken.

Uh...which brings up the subject of tests. I now understand enough about
test to suggest that perhaps the test suite for rubygems isn't doing its
job. Just a thought. Time for a little "heckle" session?

Oh well. Having 60 gems installed when only 25 are needed is tolerable.
Won't need a bailout on this one...!

t.
But what do I know?

gem cleanup doesn't handle multiple gem repos well yet, this may be
your problem:

$ gem list -d rails

Some areas are covered very well, others are not.

I am eagerly awaiting your patches. Dedicated patch providers get
commit.

As Eric noted, the trouble comes about when you have multiple
repositories. There may be good reason for such a setup, but if there
isn't _and_ most of your outdated gems are in one of them, you could
just blow that one away (rm -rf).

In my case the only reason i've had multiple repos is when i forget to
sudo and end up with gems in ~/.gem. I've blown that one away a
couple times and that hasn't bothered rubygems any, as far i can tell.

Cheers,
lasitha.

Ahem. Familiar with the problem am I.

oh man. Your apparent (if not actual!) faith in my coding abilities is
easily the highlight of my day. In only it were true....

Bingo. That's it. I have ruby 1.8.7 installed, and recently installed
1.9 as well. It never occurred to me that Rubygems was catching both
installs, and that is clearly the case. Hadn't used the 'gem list -d {}'
command until I read your email. Problem explained, if not solved.
Interesting....

A day full of bright spots of all sorts!

I forgot the workaround:

sudo sh -c 'GEM_PATH=`gem env home` gem cleanup'
