rvm use 2.1.0 --default then when i run gem install rails -v 4.1.1 I am getting: ERROR: While executing gem ... (NoMethodError) undefined method 'ord' for nil:NilClass

UPDATE:

After creating new gemset with ruby 2.1.0 in a project directory when i use this new gemset and trying to install bundle I got :

home/awlad/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- bundler (LoadError)
        from /home/awlad/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require'
        from /usr/bin/bundle:7:in `<main />

After use: \curl -sSL https://get.rvm.io | bash -s stable --rails

It is working for built in ruby version which one was installed by above command. When I am trying to installed other ruby version and gemset then I am getting above bundler load error.

Anyone can help me to get rid of this? I will provide any other information if needed.

Thanks

Try:

gem update --system

You can also update your system that might solve your problem, see here.

I suppose the problem is that bundle is here /usr/bin/bundle. I am not 100% sure, but I think that gem install bundle will override the bundle in /usr/bin/bundle.

I am answering and accepting this question because someone may get help from this.

After investigating few days ( googling, creating new issue in rvm) I have found that it is a Ruby bug was fixed here

I had to upgrade ruby version to 2.1.7 to solve this issue.

You can get details from rvm issue tracker.
