title: cannot import name 'Flask'
body: <p>Im using window 10, I did the command pip install flask but I kept getting a ImportError: cannot import name 'Flask'. When I worked with flask couple months back it was running fine. Came back to run my old programs today and i get this error? I was just trying to run a simple html website.</p>
  
  <pre><code>from flask import Flask, render_template
  from flask import request
  
  app = Flask(__name__)
  
  app.static_folder = 'static'
  
  @app.route('/')
  def index():
  
  return render_template('index.html')
  
  
  if __name__=='__main__':
  app.run(debug = True)
  </code></pre>
  
  <p>Also before this error I had No module named 'Flask' so I did(found this in other stackoverflow post):
  1. virtualenv
  2. pip install flask (getting output that requirements are already satisfied)
  3. Then I just try to run my flask which is called i.py and I get cannot import name 'Flask'. Went through many solutions on here still no idea how to fix it.</p>
