    <p>I believe the issue is where RVM places your dependencies - global vs your user folder. From a book called "Agile development with rails":</p> <blockquote> <p>First, you’ll need to make sure you have Xcode 3 or later installed...</p> </blockquote> <pre><code>$ xcodebuild -version </code></pre> <blockquote> <p>If you have Xcode version 3 installed, you’ll need to install the Git version control system separately. Verify your installation by running the following command:</p> </blockquote> <pre><code>$ git --version </code></pre> <blockquote> <p>Next, install RVM itself:</p> </blockquote> <pre><code>$ curl -L https://get.rvm.io | bash -s stable </code></pre> <blockquote> <p>Exit your command window or Terminal application and open a new one. This causes your .bash_login to be reloaded. Execute the following command, which provides additional installation instructions tailored to your specific operating system:</p> </blockquote> <pre><code>$ rvm requirements </code></pre> <blockquote> <p>Look for the line that tells you how to install the necessary OS dependencies for Ruby (MRI). Once you complete those instructions, you can proceed to install the Ruby interpreter itself:</p> </blockquote> <pre><code>$ rvm install 2.0.0 </code></pre> <blockquote> <p>The preceding step will take a while as it downloads, configures, and compiles the necessary executables. Once it completes, use that environment, and install rails:</p> </blockquote> <pre><code>$ rvm use 2.0.0 $ gem install rails --version 4.0.0.beta1 --no-ri --no-rdoc </code></pre> <blockquote> <p>With the exception of the rvm use statement, each of the above instructions need only be done once. The rvm use statement needs to be repeated each time you open a shell window. The use keyword is optional, so you can abbreviate this to rvm 2.0.0. You can also choose to make it the default Ruby interpreter for new terminal sessions with the following command:</p> </blockquote> <pre><code>$ rvm --default 2.0.0 </code></pre> <blockquote> <p>You can verify successful installation using the following command:</p> </blockquote> <pre><code>$ rails -v </code></pre> <p>If you have trouble, try the suggestions listed under the Troubleshooting Your Install heading on the rvm site.</p> <p>Hope that does it for you!</p>

    1. COI do find I missed some rvm requirements. Once that's sorted, `rvm install 2.0.0` does return similar error still. but running `rvm rubygems latest` after that will install rubygems successfully.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
