<p>I have installed the AWS CLI around 6 moths back and upgraded using the following command today.</p>

<p><code>pip install --upgrade awscli</code></p>

<p>The current version on my Ubuntu 18.04 machine is:</p>

<pre><code>aws-cli/1.14.44 Python/3.6.5 Linux/4.15.0-23-generic botocore/1.8.48
</code></pre>

<p>When I try aws eks command, I am getting the following error:</p>

<pre><code>Invalid choice: 'eks', maybe you meant:
    * es 
</code></pre>

<p>Is my aws cli is upgraded properly or should I install something else for EKS service?</p>

<p>I had the same issue on El Capitan 10.11.6 and the only one worked solution was this:</p>

<p><code>sudo pip install awscli --ignore-installed six</code></p>

<p>Version 6 comes with distutils in El Capitan</p>
