title: How to upgrade AWS CLI to the latest version?
body: <p>I recently noticed that I am running an old version of AWS CLI that is lacking some functionality I need:</p>
  
  <pre><code>$aws --version
  aws-cli/1.2.9 Python/3.4.3 Linux/3.13.0-85-generic
  </code></pre>
  
  <p>How can I upgrade to the latest version of the AWS CLI (1.10.24)?</p>
  
  <p>Edit:</p>
  
  <p>Running the following command fails to update AWS CLI:</p>
  
  <pre><code>$ pip install --upgrade awscli
  Requirement already up-to-date: awscli in /usr/local/lib/python2.7/dist-packages
  Cleaning up...
  </code></pre>
  
  <p>Checking the version:</p>
  
  <pre><code>$ aws --version
  aws-cli/1.2.9 Python/3.4.3 Linux/3.13.0-85-generic
  </code></pre>
