title: No module named openpyxl - Python 3.6 - OSX
body: <p>I've installed <code>openpyxl</code> from the Terminal using</p>
  
  <pre><code>pip3 install openpyxl
  </code></pre>
  
  <p>without any problems. I've even double-checked by simply running <code>import openpyxl</code> from the Terminal window once Python is running, and it imports no problem.</p>
  
  <p>The problem starts when I try and import <code>openpyxl</code> from a script I'm building to work with a spreadsheet. I'm using Sublime Text and can't even get past the <code>import openpyxl</code> at the beginning of the script without running into the following error:</p>
  
  <blockquote>
    <p>Traceback (most recent call last):
          File "/Users/wcw/Desktop/test.py", line 1, in 
            import openpyxl
        ImportError: No module named openpyxl</p>
  </blockquote>
  
  <p>How can this be happening? I know I've installed <code>openpyxl</code> correctly from the Terminal window without any errors so how can my script not find the module?</p>
