How can I uninstall software from an RHEL 5 system?

  • 772

I installed Rubygems 1.3.4 on an RHEL 5 system. The way you install that is to download source and run setup.rb. I did not find a package for it through yum list available.

Now I'd like to uninstall it because I've decided to use a different version of Rubygems. There is no install log file or any list of where the installer put stuff. It isn't immediately clear from looking at setup.rb where things went.

Any thoughts?

    RubyGems 1.3.4 is the latest version. Generally, if you're going to use gems to install Ruby libraries, you'll want to run the latest possible version of it. If you're planning to install an RPM packaged version instead of the RubyGems-from-source, you should start by looking in /usr/local/lib/site_ruby and /usr/lib/ruby/gems.

    Software you install outside 'rpm' and 'yum' (and up2date, though rarer) on RHEL won't be in the RPM database, so those tools won't know anything about it.

  2. This is really more of a ruby/gems question than a redhat/package-management question.

    I believe you can use "gem list" and then "gem uninstall NAME" to remove any individual "gems" (ruby packages), but I don't know how you can uninstall gem itself.

    gems is its own (broken) ruby-specific package-management system. There's Ruby people that don't understand RPM well that think it's superior in ways that might be useful for programmers on a dev box but is mostly a pain for sysadmins on production boxes.

  3. To update rubygems itself, the best way is to install rubygems-update

    sudo gem install rubygems-update

    This will update your rubygems install to the latest version. It's as easy as that.
