Target WSGI script cannot be loaded as Python module Raspberry Pi

Question

I'm using a raspberry pi with debian linux mod_wsgi and flask. I used this tutorial to set everything up and the python script will run if I run the command

python myFile.py

However, when I try to run it from apache I get an HTTP 500 error.

This is my wsgi file:

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)

sys.path.insert(0,'/var/www/FlaskApp/')

from FlaskApp import app as application

this is my .conf file:

<VirtualHost *:80>
                ServerName (my-server-ip)
                ServerAdmin (my-Email)
                WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi
                <Directory /var/www/FlaskApp/FlaskApp/>
                        Order allow,deny
                        Allow from all
                </Directory>
                Alias /static /var/www/FlaskApp/FlaskApp/static
                <Directory /var/www/FlaskApp/FlaskApp/static/>
                        Order allow,deny
                        Allow from all
                </Directory>
                ErrorLog ${APACHE_LOG_DIR}/error.log
                LogLevel warn
                CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

these are the permissions on the wsgi file

-rw-r--r-- 1 root root  211 Jul 30 18:51 flaskapp.wsgi

I've looked at many different tutorials but have yet to find a solution...

I am sure that I am not running a virtual environment for my python file and know that that could be an issue but am unsure how to solve that. Thanks for the help in advance.

this is the error that Im getting:

What are the list of files/directories in /var/www/FlaskApp and /var/www/FlaskApp/FlaskApp? What version of Python is mod_wsgi compiled for? What version of Python is your code meant to be written for? — Graham Dumpleton

Hey Graham, thanks for replying to my thread. I've seen that you have answered this problem for others: /var/www/FlaskApp contains [FlaskApp and flaskapp.wsgi] /var/www/FlaskApp/FlaskApp contains [myFile.py] my python code is written for python 2.7 however I'm not sure what version of python mod_wsgi is compiled for. How would I find out? — user8395102

I found it Graham, mod_wsgi: Compiled for Python/2.7.8. mod_wsgi: Runtime using Python/2.7.9. Hope this helps you help me — user8395102

So you do or don't have a __init__.py file in /var/www/FlaskApp/FlaskApp. You need to have it if being run with Python 2. This is why asked what Python version code was set up for. Python 3 doesn't require that file. The difference between 2.7.8 and 2.7.9 doesn't matter. — Graham Dumpleton

This answer came from Graham Dumpleton:

When using python 2 there must be a file named __init__.py in the project folder! In my case the path to that folder happened to be /var/www/FlaskApp/FlaskApp.
