This is a very odd one and I’m not sure how to proceed.

Basically, I am able to install gems and use them normally within any folder except those created with rails. It’s very very odd. It’s difficult to explain so maybe this console output will explain

    passenger@rubyserve:~/railsapps$ ls
    app  test_application  testing
    passenger@rubyserve:~/railsapps$ rails -v
    Rails 3.2.2
    passenger@rubyserve:~/railsapps$ 
    passenger@rubyserve:~/railsapps$ 
    passenger@rubyserve:~/railsapps$ cd app/
   passenger@rubyserve:~/railsapps/app$ ls -a
   .   app     config.ru  doc      Gemfile.lock  lib  public    README.rdoc  test  vendor
   ..  config  db         Gemfile  .gitignore    log  Rakefile  script       tmp
    passenger@rubyserve:~/railsapps/app$ 
    passenger@rubyserve:~/railsapps/app$ 
    passenger@rubyserve:~/railsapps/app$ rails -v
    The program 'rails' is currently not installed.  To run 'rails' please ask your administrator to install the package 'rails'
    passenger@rubyserve:~/railsapps/app$

It makes bugger all sense. When outside my rails folder, I can call rails to make a new application but once within, rails isn’t detected. This is the same for all gems including bundler.

My first thought was that somehow, rails had some specific gem folder hidden away, so I done my gem install from within the rails project, however this didn’t work either.

Any thoughts?

My setup is ubuntu server 10.10 (I know, i know)
Ruby 1.9.2
gem 1.8.17
and I’m using the latest rvm from wayneeseguin.enter code here

    This type of problem some time occurs i think u can save a lot of time by installing and using RVM

    After installing RVM create gemset directory every time whenever you create separate project. e.g you create application blog first you create gemset directory with giving this command

    rvm gemset create blog

    then you should use this gemset directory and also ruby version as well e.g you have install ruby 1.9.2 then use this command 

    rvm use ruby-1.9.2@blog

    after that go into directory of blog application and install this gem

    gem install bundler

    and also then bundle install. so all local gem will be installed into this blog directory under rvm and there will be no conflicts will be appear.But keep one thing in mind if your platform is ubuntu then this will work
