Weird gem issues

[Mike Rood]

I have created many rails projects successfully on Windows and OSX over the past 8 years or so.  I'm trying to create my first project on CentOS and I'm getting the strangest errors.  I have installed rails 4.1.4 and rake 10.3.2.  

rake -v  returns:

  Could not find gem 'rails (= 4.1.4) ruby' in the gems available on this machine.

  Run `bundle install` to install missing gems. 

gem list rails* returns 

  *** LOCAL GEMS ***

  coffee-rails (4.0.1)

  jquery-rails (3.1.1)

  rails (4.1.4)

  railties (4.1.4)

  sprockets-rails (2.1.3)

bundle install returns:

  Bundler::GemspecError: Could not read gem at /src/opsdocs/vendor/bundle/ruby/2.1.0/cache/rake-10.3.2.gem. It may be corrupted.

  /usr/local/rvm/gems/ruby-2.1.1@global/gems/bundler-1.6.2/lib/bundler/vendor/thor/shell/basic.rb:355: warning: Insecure world writable dir /usr/local/rvm/gems/ruby-2.1.1 in PATH, mode 042777

  An error occurred while installing rake (10.3.2), and Bundler cannot continue.

  Make sure that `gem install rake -v '10.3.2'` succeeds before bundling.

rails s  returns

   /usr/local/rvm/rubies/ruby-2.1.1/lib/ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'railties' (>= 0) among 8 total gem(s) (Gem::LoadError)

    from /usr/local/rvm/rubies/ruby-2.1.1/lib/ruby/2.1.0/rubygems/dependency.rb:309:in `to_spec'

    from /usr/local/rvm/rubies/ruby-2.1.1/lib/ruby/2.1.0/rubygems/core_ext/kernel_gem.rb:53:in `gem'

    from /usr/local/rvm/gems/ruby-2.1.1/bin/rails:22:in `<main>'

    from /usr/local/rvm/gems/ruby-2.1.1/bin/ruby_executable_hooks:15:in `eval'

    from /usr/local/rvm/gems/ruby-2.1.1/bin/ruby_executable_hooks:15:in `<main>'

I have uninstalled and reinstalled rake 10.3.2 several times. 

WTF?  Any ideas?

I've seen this before when I was missing some (but not all) of the right executables on my PATH. `gem list` would show one set of gems, but `rake` would pick up an entirely *different* set in the system Ruby (or vice versa). Run `which ruby` etc and see what doesn't line up.
