using gems installed via 'sudo gem install'

    I've installed ruby-opengl through sudo gem install because there were
    errors otherwise and now I can't use it with 'ruby main.rb'. When I
    typed 'sudo ruby main.rb' I think it worked but there were errors
    considering hashes as they're changed in latest version of ruby (I think
    I have different ruby versions as I'm also using RVM).
    I know it's confusing but is there a way to somehow transfer gem from
    root to rvm or maybe a way to access roots gems without sudo triggering
    wrong version of ruby?


    gem install ruby-opengl fails saying that it can't find rake executable
    for rake-0.8.7. I can install rake via 'gem install' but it doesn't
    really work because I can install it multiple times without it
    complaining about rake being already installed.

    Well, if you didn't do a "sudo rvm gem install" (or whatever the
    syntax is RVM uses to install gems), then your installed gem lands in
    the system-wide gem repository, which isn't accessible if you switch
    Ruby versions via rvm.

    Create a gemset:
    http://rvm.beginrescueend.com/gemsets/

    That seems to be the easiest way (unless you can install gems via RVM
    itself; pik can do that for us Windows users, so I doubt RVM can't do
    that).

    RVM's documentation should also reveal a means to sync gems across
    different Ruby versions managed by RVM.

    Though the folk I have met,
    (Ah, how soon!) they forget
    When I've moved on to some other place,
    There may be one or two,
    When I've played and passed through,
    Who'll remember my song or my face.

    I have gemset created but I don't know how is that helping because there
    is no rvm command (that I aware of) to import gem to gemset other that
    'rvm gem install' and this isn't working (same error).
    Also I can't use 'sudo rvm gem install' because it says 'rvm: command
    not found' even though I have rvm in my 'sudo gem list'

    No it's not.

    "I think I have different ruby versions as I'm also using RVM" -- WTF?
    You "think"??? If you can say that, you may have RVM installed, but
    you're *not* "using" it.

    In a terminal --

    prompt$ rvm list

    You'll see what rubies you have installed under rvm. Pick one, e.g.

    prompt$ rvm use 1.8.7

    prompt$ rvm gemset list # now pick one of those, e.g.

    prompt$ rvm use 1.8.7@example

    prompt$ gem list

    Now, forgetting about 'sudo' altogether, which you shouldn't use with
    RVM (unless you're explicitly using the `system` ruby) install the gems
    you need.

    prompt$ gem install ruby-opengl

    If at any point you have an error, STOP and figure out what's wrong
    instead of just blindly cascading errors into the dog's breakfast you've
    described above.

    HTH, and good luck,

    I am using rvm with 1.9.2 version and by what I said before I meant that
    there was an older version of ruby preinstalled in my system (ubuntu
    10.10).

    I couldn't find a solution to my problems and then it somehow worked
    using sudo (gem installation) therefore I was wondering if there is a
    different way to do it.

    There is only one error (without sudo)
    "ERROR: Failed to build gem native extension" and then there is a bunch
    of stuff with "'bin_path': can't find executable rake for rake-0.8.7"
    somewhere in the first couple of lines.
    I was searching through some forums where this error was appearing
    because of white spaces in Windows folders. But I'm using linux and
    everything seems fine especially because it is all working just fine
    using 'sudo'.

    If it's "all working just fine" then why are you posting?

    Alternatively, if you want to use the rvm version of Ruby, then fix the
    problem installing the gem you want.

    At least, that's what I would do.

    The installation is working (with sudo). But I can't use the gem in my
    project as it's outside of the rvm's scope.

    I have no idea why you don't understand what I'm trying to say.
    Seriously I said it's a little confusing but you disagreed with me.

    I CAN install this gem using 'sudo gem install' but then I can't use it
    in rvm. I CAN'T install this gem without sudo just by 'gem install'
    because it produces said error.

    What error? Instead of vaguely describing it, why don't you *fix* it?

    You could start by saying *exactly* what gem and version you're
    talking about, and showing the *entire error message*.

    What you want is this:

    rvmsudo gem install

    rvm works by changing your $PATH. When you switch users with sudo, that
    changes your $PATH too. rvmsudo lets you also temporarily change the $PATH
    of your administrator account, so that you can install gems properly while
    still having increased permissions.

    To my surprise it isn't working. rvmsudo gem install ruby-opengl still
    gives me the same error.
    I checked and installed ruby-opengl with 'sudo gem install' and it's
    working.

    It's not that you're doing it as root, it's that you're using a different
    (system) version of Ruby.

    It installs for me (Mac OS 10.6.6) just fine using 1.8.7, but fails in the
    same way with 1.9.2. Are you sure the gem itself works with 1.9.2?

    it says "Proper support for ruby 1.9/1.9.1+" so I assumed that it will
    work just fine with 1.9.2 as I never had any problems with any other
    gem.

    find rake.gemspec that is inside ruby-1.9.2-p136/lib/ruby/ and remove
    it.

    install rake again (gem install rake).

    Then gem install ruby-opengl again.

    There must be something that gem is doing during the extension
    compilation phase, perhaps "sudo form inside of it" that is affecting
    RVM functionality.

    But try above steps first. Can't find rake is a problem of Ruby 1.9.2-
    p0 and p136 is already fixed.
