This code

code:

import sys

#TB I need to setup virtual env

activate_this = '/home/huhu/.virtualenvs/wv_venv/bin/activate_this.py'
exec(activate_this, dict(__file__=activate_this))

sys.path.append('/home/tbumgarner/webapps/chs_web_viewer/web_viewer')
import app as application

is leading to this error. I for the life of me have no idea why this is happening.

code:

     exec(activate_this, dict(__file__=activate_this))
   File "<string>", line 1
     /home/huhu/.virtualenvs/wv_venv/bin/activat$

 SyntaxError: invalid syntax

I was following this tutorial and had to change the execfile() command for python3.

Check the documentation for python 3's exec(): https://docs.python.org/3/library/functions.html#exec

"This function supports dynamic execution of Python code. object must be either a string or a code object. If it is a string, the string is parsed as a suite of Python statements which is then executed (unless a syntax error occurs)."

So the problem is that you're passing the string "/home/huhu/.virtualenvs/wv_venv/bin/activate_this.py'" to the exec() function, which is just a path and not really python code, hence the syntax error.
