UAAC command line-utility not work
<p>We are working on Predix Mobile SDK.So we are try to set Predix Mobile Development Environment for that we need set <code>UAAC command line-utility</code> .We flowed this link (<a href="https://github.com/cloudfoundry/cf-uaac" rel="nofollow">https://github.com/cloudfoundry/cf-uaac</a>).
For Install we tried like this </p>

<pre><code>gem install cf-uaac
</code></pre>

<p>We got error this </p>

<pre><code>ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/bin directory.
</code></pre>

<p>after that we google about this error but we got nothing .Please guide to us for UAAC CLI.</p>
