Permission error while trying to install Rails (OSX)

I am new to programming and trying to set rails on my terminal. I followed instructions from a friend by installing the xcode, homebrew, git, rbenv, ruby-build, ruby ​​gems, ruby ​​and postgres command line tools. But whenever I try to install the gem installation rails, I get the following:

Russell-Silvers-MacBook-Pro:~ Russell_Silver$ gem install rails ERROR: While executing gem ... (Errno::EACCES) Permission denied @ rb_sysopen - /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/rails-4.2.0/README.md

This is especially unpleasant because when I run the $ gem list, it says that I have rails 3.2.18. Which is characteristic, because when I run $ rails v $, it tells me that I have Rails 4.2.0.

When I try to use rails rails my new_app

 Errno::EACCES: Permission denied @ rb_sysopen - /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/rails-4.2.0/README.md An error occurred while installing rails (4.2.0), and Bundler cannot continue. Make sure that `gem install rails -v '4.2.0'` succeeds before bundling. run bundle exec spring binstub --all /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/shared_helpers.rb:83: warning: Insecure world writable dir /Users/Russell_Silver in PATH, mode 040707 bundler: command not found: spring Install missing gem executables with `bundle install` Russell-Silvers-MacBook-Pro:~ Russell_Silver$ bundle install /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/bundler-1.8.3/lib/bundler/vendor/thor/shell/basic.rb:355: warning: Insecure world writable dir /Users/Russell_Silver in PATH, mode 040707 Could not locate Gemfile or .bundle/ directory

This is really frustrating, especially for someone new to programming, such as myself, so I'm looking for help from anyone who may know what is wrong.

Your rbenv installation was not installed correctly, as it had elevated privileges, which prevented your user account from writing to ~/.rbenv .

Run the following command to get ownership of the directory:

  sudo chown -R Russell_Silver ~/.rbenv

Note that some users may have a different rbenv directory, for example. /usr/local/var/rbenv . This will replace ~/.rbenv in the command above.
