title: Boto3 and AWS CLI incompatibility issue
body: <p>I executed command <strong>pip3 install awscli --upgrade --user</strong> on my MAC and got the following:</p>
  
  <pre><code>boto3 1.8.8 has requirement botocore&lt;1.12.0,&gt;=1.11.8, but you'll have botocore 1.12.160 which is incompatible.
  boto3 1.8.8 has requirement s3transfer&lt;0.2.0,&gt;=0.1.10, but you'll have s3transfer 0.2.0 which is incompatible.
  </code></pre>
  
  <p>I'm looking for a work around. </p>
  
  <p>Thanks in advance.</p>
