Could not find RubyGem bundler

Question

I've cloned diaspora for github, git://github.com/diaspora/diaspora.git

I tried to install it. An error generated when I use bundle install.

$ bundle install 
/usr/local/lib/site_ruby/1.8/rubygems.rb:812:in `report_activate_error': Could not find RubyGem bundler (>= 0) (Gem::LoadError)
    from /usr/local/lib/site_ruby/1.8/rubygems.rb:223:in `activate'
    from /usr/local/lib/site_ruby/1.8/rubygems.rb:1146:in `gem'
    from /usr/bin/bundle:18

I'm using rails 3 and ruby 1.8 on ubuntu 11.04. How to fix it? Please help

Answer 1

Did you install bundler gem?

$ gem install bundler

You might need sudo privileges.

Answer 2

Hmm, maybe you've got the bundle command and bundler gem installed for /usr/bin/ruby, and after that installed another Ruby in /usr/local/bin/ruby?

Could you do a which ruby and head -1 /usr/bin/bundle? Maybe also a gem list?

Answer 3

Presumably this has been fixed long ago, but for the benefit of others....

My issues was that while I had installed the bundler gem it had been installed in a different location to the current GEM_PATH - so it couldn't be found.

So,

GEM_PATH=/usr/lib/ruby/gems/1.8/ bundle install

did the business, setting the value of GEM_PATH to the actual location of the gems folder where the bundler gem has been installed.
