title: No such file or directory with Flask
body: <p>flask question: I have my <code>run.py</code> file in the following dir </p>
  
  <pre><code> /Users/`&lt;username&gt;`/Python_stuff/flask
  </code></pre>
  
  <p>but when I run it it says</p>
  
  <pre><code>(api_automation)MacBook-Pro:flask `&lt;username&gt;`$ ./run.py
  -bash: ./run.py: flask/bin/python: bad interpreter: No such file or directory
  </code></pre>
  
  <p>I'm confused as to why this is happening when its worked in the past on other virtualenv's</p>
  
  <p>here is what the run.py looks like:</p>
  
  <pre><code>#!flask/bin/python
  
  from app import app 
  app.run(debug = True)
  </code></pre>
