Rails3 server and bundler error: uninitialized constant Bundler (NameError)

Question

I just install rails 3 and all gems that it need, but when I try to start server, it says about problem in boot script.

[rap-kasta@acerAspire testR3]$ script/rails server  
/home/rap-kasta/tmp/testR3/config/boot.rb:7:in `rescue in <top (required)>': uninitialized constant Bundler (NameError)  
        from /home/rap-kasta/tmp/testR3/config/boot.rb:2:in `<top (required)>'  
        from script/rails:9:in `require'  
        from script/rails:9:in `<main>  

So, I tried to reinstall Bundler, install "pre"-version (but really it has version number lower then i install by gem install bundler

Now there are next gems in system:

abstract (1.0.0)
actionmailer (3.0.0.beta, 2.3.5, 2.3.4)
actionpack (3.0.0.beta, 2.3.5, 2.3.4)

activerecord (3.0.0.beta, 2.3.5, 2.3.4)
activeresource (3.0.0.beta, 2.3.5, 2.3.4)
activesupport (3.0.0.beta, 2.3.5, 2.3.4)
arel (0.2.1, 0.2.pre)
builder (2.1.2)
bundler (0.9.5)
erubis (2.6.5)
fxri (0.3.7)
fxruby (1.6.20)

text-format (1.0.0)
text-hyphen (1.0.0)
thor (0.13.2, 0.13.1)
tzinfo (0.3.16)

Also, there is same error with rails console and similar with bundle check:

[rap-kasta@acerAspire testR3]$ bundle check
/usr/lib/ruby/gems/1.9.1/gems/bundler-0.9.5/bin/bundle:12:in `rescue in <top (required)>': uninitialized constant Bundler::BundlerError (NameError)
        from /usr/lib/ruby/gems/1.9.1/gems/bundler-0.9.5/bin/bundle:10:in `<top (required)>'
        from /usr/bin/bundle:19:in `load'
        from /usr/bin/bundle:19:in `<main>'

Solution 1

It isn't a bug in Bundler (or Rails), It's a bug (?!) in gems system, I think... So.. I also have gem 'rawr', which have file 'bundler.rb' and gems system load it instead of 'bundler/../bundler.rb'.

I removed rawr, but now I can't use jemini... But my problem closed now.

Solution 2

it works after adding:

gem install bundler

and after adding:

gem 'bundler'

in line 2 in config/boot.rb (just after require 'rubygems')

Solution 3

Please confirm paths of ruby and rake command.

$ which ruby
/usr/bin/ruby
$ which rake
/usr/local/bin/rake

I got the same error. In my case, I installed Rails with /usr/bin/ruby, but rake uses /usr/local/bin/ruby. This is why I got the error related to Bundler.
