Unable to install rack gem

Robert Stackhouse

5/19/2009 12:21:00 PM

I have been trying to install the twitter gem on Ubuntu and have been
unable to do so. Rack and Thin are both dependencies of the twitter gem
and there seems to be a circular dependency between rack and thin. When
I try to install rack I get:

user@user.com:~$ gem install rack

I get the following if I try to install thin:

rstackhouse@rstackhouse:~$ sudo gem install thin
Select which gem to install for your platform (x86_64-linux)
1. thin 1.2.1 (i386-mswin32)

4. thin 1.0.0 (i386-mswin32)
5. Skip this gem
6. Cancel installation

So it seems pretty obvious to me that there is a circular dependency
between these two gems. Can anyone help me resolve this problem?

Uh, well --

What version of ruby and rubygems are you running? This was on:
[hassan@sailboat ~]$ gem env
RubyGems Environment:
- RUBYGEMS VERSION: 1.3.1
- RUBY VERSION: 1.8.7 (2009-02-16 patchlevel 5000) [i686-linux]

FWIW,

I am running:

user@user.com:~$ gem env
RubyGems Environment:
- VERSION: 0.9.4 (0.9.4)
- INSTALLATION DIRECTORY: /var/lib/gems/1.8
- GEM PATH:
- /var/lib/gems/1.8
- REMOTE SOURCES:
- http://gems.rub...
user@user.com:~$ ruby --version
ruby 1.8.6 (2007-09-24 patchlevel 111) [x86_64-linux]

Looks like I am running a much older version of rubygems than you are
Hassan. Where/how could I get a more recent version?

I tried "gem update --system" then I got:

user@user.com:~/rubygems-1.3.3$ gem ver
/usr/bin/gem:10: undefined method `manage_gems' for Gem:Module
(NoMethodError)


So I googled around and was lead to this page:
http://www.jaredlog.com/?p=1045&d.... I tried his approach and
got the same error message as above.

Anyone got any ideas?

Perhaps you need to upgrade by manually installing. Which version of
gem do you have?
