Error: ImportError: No module named flask while installing flask application on ubuntu with apache2 server

I am trying to launch a simple flask application. I get the following error when I open the website:

[Tue Jan 03 05:06:43.521815 2017] [wsgi:error] [pid 16996] [remote 223.176.176.72:37742] mod_wsgi (pid=16996): Exception occurred processing WSGI script ‘/var/www/myyu/myyu.wsgi’.

I tried disabling virtualenv using the following command: a2dissite 000-default I also enable the myyu.conf file I created. My wsgi file looks like: import sys

sys.path.insert(0, “/var/www/myyu”)

from init import app #Put logging code (and imports) here … application = app

Here’s the directory structure: /var/www/myyu: myyu.wsgi init.py

I have also verified that app.run() is under if name == “main”: condition.

Can somebody please help?
