'gem install' and 'sudo gem install'

I've got an issue installing gems on my mac (os 10.6).

I used to be able to run 

gem install <gem-name-here>

but after updating something, it could be the version of gem I'm using, but it's unlikely, I now get the error:

ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions into the /usr/bin directory.

On the face of it, it looks like my 'GEM_HOME' isn't set. If so, why has this been unset, and how can I change it back?

Secondly - when I run 

gem list

I see all gems - including those in ~/.gem, but when I run:

gem server

I only see gems in /usr/bin... strange huh?

Any help would be great to resolve this - I dont like using sudo to install gems constantly.

Follow the instructions in this guide:

export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH

gem install <gem-name-here>

If you were already doing this, completely delete the ~/.gem directory and try again.

Have you tried doing $bundle update after installing the gems that you wanted?

  1. Install RVM.
  2. Profit!

It really is that simple. In addition, you will be able to install and easily switch between different Ruby versions and sets of gems with a single command. It will all be installed in ~/.rvm (by default) and you won't need to use sudo to install gems.
