title: Pip install doesn't add module to python in Microsoft Azure
body: <p>I want to run a python script in Microsoft Azure. For that purpose I followed the tutorial <a href="https://docs.microsoft.com/en-us/azure/app-service/app-service-web-get-started-python" rel="nofollow noreferrer">here</a>.</p>
  
  <p>Downloaded the sample code, ran <code>pip install -r requirements.txt</code>, got a message that <code>flask</code> was installed successfully but when I ran <code>python main.py</code> , I get the error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "main.py", line 1, in &lt;module&gt;
      from flask import Flask
  ImportError: No module named 'flask'
  </code></pre>
  
  <p>If I open python and run <code>help('modules')</code> , flask is not listed there although I supposedly just installed it. I have the same problem with other modules.</p>
