ModuleNotFoundError: No module named 'webpush' - django

I am using webpush in my Django application. Following the recommendation it works well locally.
When I push the code to my host, it gives me this mistake ModuleNotFoundError: No module named 'webpush'.
Application does not work.

I have the Error when I try to reload the application on host.
Anyone can help?

I have looked at the similar question on stackoverflow but still cant figure out what is wrong at my end.
Any pointers/help would be appreciated.
From taking a look it looks like the folder structure is fine.
What you might need to do is add the module into your INSTALLED_APPS in settings.
Or, if you're getting an import error or a module not found error for something that you believe is installed, then you've probably installed it into a version of Python or virtualenv that your code is not running in. If it's part of your code that is not being found, then your Python path is not set up so that it sees the module you're trying to import. See https://help.pythonanywhere.com/pages/DebuggingImportError/
The error is resolved.
The problem was that environ is not a function but a process parameter and hence, using it like below was the cause of the error.
os.environ('DJANGO_SETTINGS_MODULE', 'myapp.settings')
I changed the code to:
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
and the error was solved.

If you run pip3 install pymysql in your local computer, this does not mean that when you deploy the app this module is packaged. In fact GAE attempts to install everything at build time using your requirements.txt file so it doesn't matter if you installed everything in your PC since GAE will not use what you have in local (talking about packages installed with pip).
Checking your requirements.txt file I do not see that the package PyMySQL is added. You should add it to that file and attempt to deploy again.
"pymysql" package is missing (not installed) according to the message below from your error:
ModuleNotFoundError: No module named 'pymysql'
So, you need to run this command below to install "pymysql":
pip install pymysql

Problem when starting gunicorn with .sh (No module named '.0')

I'm trying to start a flask application with gunicorn but i'm facing an issue.
When starting it from command line it works fine with this command:
/usr/local/bin/gunicorn --preload --certfile /etc/letsencrypt/live/server_name.net/fullchain.pem --keyfile /etc/letsencrypt/live/server_name.net/privkey.pem -w 17
-b 0.0.0.0:9090 wsgi:app
The same command from a .sh script raise an error :
Traceback (most recent call last):

File "/usr/local/lib/python3.4/dist-packages/gunicorn/util.py", line 372, in import_app
__import__(module)
ImportError: No module named '.0'
Both cli and .sh are run as root.
The same script works fine on a different server so i guess there is a problem with the environment.
I tried to add in the script the following lines at the beginning of the script without success:
$PYTHONPATH=/path/to/my/app
and
$PWD=/path/to/my/app
This is the wsgi file i'm using:
from api import app
if __name__ == "__main__":
app.run()
Any idea what the problem could be?
I was finally able to solve this problem. The following script seems to be working:
cd /path_to_app/
gunicorn --certfile=/etc/letsencrypt/live/server_name.net/fullchain.pem --keyfile=/etc/letsencrypt/live/server_name.net/privkey.pem -w 4 -b 0.0.0.0:9090 wsgi:app

ImportError: No module named 'django_select2'

I am trying to deploy my django application on the pythonanywhere. I have install all the packages that requires for the application. I am also using django_select2 reusable app in my application.
Firstly, i activate virtual environment and install the django_select2 by this command :
$ pip install django_select2
When i execute below command
$ pip freeze
cryptography==2.2.2
Django==2.0.7
django-appconf==1.0.2
django-select2==6.1.0
Flask==1.0.2
Flask-JWT==0.3.2
Flask-SQLAlchemy==2.3.2
furl==1.2
idna==2.7
As you see django_select2 is also in the installed list. I also check site-packages inside my virual environment. There is also django_select2 folder.
However when i run my app it generates the ImportError: No module named 'django_select2' inside my error.log
Here is the part of my error.log

Any suggestions? What i have missing?
The problem is application is not using virtual environment in this case. If we look at the below line we will see /usr/local/... . So the application is using pythonanywhere.com default environment.
File "/usr/local/lib/python3.5/dist-packages/django/core/wsgi.py", line 13,
which means whatever we install in our virtualenv has no effect on default server. In pythonanywhere.com there is virtualenv menu, be sure if you input correct path info in this menu.
The default pip on PythonAnywhere is for Python 2.7, so you've been installing your modules into the wrong version of Python (your web app is using 3.5). Use pip3.5 to install your modules.

Tried to restart apache, but it's not working. Thanks for any help!
Just found solution. I checked 'sys.prefix' in my python's interpretator and it printed '/usr/local', but I had not set WSGIPythonHome in apache config (as written in mod_wsgi docs for this case). And just for experiment I set 'WSGIPythonHome /usr'. It's strange, but it resolves my problem, everything is fine now!
