I have been trying to deploy a Django application on Heroku.
Some background - I hadn't used virtual environment while building the application but while deploying it, I had to use it. I'm following this tutorial for deployment. https://medium.com/agatha-codes/9-straightforward-steps-for-deploying-your-django-app-with-heroku-82b952652fb4
Now I'm stuck in step-6. After creating a virtual environment I have freezed the dependencies into requirements.txt
.
But when I open the deployed URL it says
ImportError at /
No module named PIL
though Pillow has been installed, it is there in requirements.txt and runs fine when hosted on a local server.
This is my requirements.txt.
certifi==2018.4.16
dj-database-url==0.5.0
Django==1.11.14
django-heroku==0.3.1
gunicorn==19.9.0
packaging==17.1
Pillow==5.2.0
pip-review==1.0
pipenv==2018.7.1
pkg-resources==0.0.0
psycopg2==2.7.5
pyparsing==2.2.0
pytz==2018.5
six==1.11.0
virtualenv==16.0.0
virtualenv-clone==0.3.0
whitenoise==3.3.1
Please help me with this.
If you are doing this in your view
import PIL
do this
import Image
Heroku? Access your application and manually run pip install -r requirements.txt
, then turn the application off and back on again.
I had this problem before, this step solved my problem.
