  <p>I use ansible and when I run it I get the following error:</p>
  
  <pre><code>fatal: [localhost]: FAILED! =&gt; {"changed": false, "msg": "Failed to import the required Python library (Docker SDK for Python: docker (Python &gt;= 2.7) or docker-py (Python 2.6)) on dd63315fad06's Python /usr/bin/python. Please read module documentation and install in the appropriate location, for example via `pip install docker` or `pip install docker-py` (Python 2.6). The error was: No module named docker"}
  </code></pre>
  
  <p>when I run </p>
  
  <pre><code>python -c "import sys; print(sys.path)"
  </code></pre>
  
  <p>I see: </p>
  
  <pre><code>['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-x86_64-linux-gnu', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/local/lib/python2.7/dist-packages/pip-19.2.2-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/fasteners-0.15-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/monotonic-1.5-py2.7.egg', '/usr/lib/python2.7/dist-packages']

  <p>and python versions are as follows:</p>
  
  <pre><code>+ python --version
  Python 2.7.12
  + python3 --version
  Python 3.5.2
  </code></pre>
  
  <p>Then as I see everything is fine and I am not sure why I get </p>
  
  <pre><code>"Failed to import the required Python library (Docker SDK for Python: docker (Python &gt;= 2.7) or docker-py (Python 2.6)) on dd63315fad06's Python /usr/bin/python.
