“ImportError: No module named sendgrid” for SendGrid in Google App Engine

Question

I followed the instruction from the https://cloud.google.com/appengine/docs/python/mail/sendgrid?hl=en and added SendGrid email support to my project.

It works perfectly on the development server but when I deploy to GAE I get “ImportError: No module named sendgrid”

I know the files are on the server (I downloaded source back from GAE to test it) and I have other third party libraries that work but not the sendgrid.

I spoke to SendGrid tech support but they point back to Google.

Here is the import line from main.py

from sendgrid import SendGridClient, Mail

The project directory structure looks like this:

-+
 |
 +sendgrid
 +smtpapi
 main.py

UPDATE:

After deleting everything and adding it back bit by bit I've finally discovered what was wrong.

I had a folder for static content called "s". I didn't mentioned it because I thought it was irrelevant. After deleting this folder - sendgrid suddenly started to work. Eventually, I've changed "s" to a longer name that does not starts with "s" and problem has disappeared.

Answer 1

install the sendgrid module in ur virtual environment using the following command

pip install sendgrid

or else u can install it as system wide module by typing

sudo apt-get install sendgrid

see how I solved it.

Answer 2

I had a folder for static content called "s" which I didn't mention in the question because I thought it was irrelevant. After I renamed this folder everything started to work. So the issue has been resolved, however the cause of it still remains a mystery ...

Answer 3

pip install sendgrid
