Travis-CI config file customization
<p>in my current travis-ci file i have this configurations.</p>

<p>NOTE: i want to customize this file as i don't have anything in <code>vendor/cache</code>. due to which am getting error on travis-ci build </p>

<pre><code>0.44s$ bundle install --local
Some gems seem to be missing from your vendor/cache directory.
Could not find rake-10.5.0 in any of the sources
The command "bundle install --local" failed and exited with 7 during .
Your build has been stopped.
</code></pre>

<p>I just want to remove this error, but am totally unfamiliar with Travis-ci. also i dont want to put any gems in vendor/cache because it will make repo so much bigger in size. any help on this? </p>
