sendgrid google app engine python DistributionNotF

Question

I am integrating Sendgrid into a Google App Engine Python project.

Sendgrid is installed through pip, and from the shell command line, functions correctly.

I have copied the sendgrid folder into my gae project folder.

Using the same example code (from sendgrid-python github page) that works in the shell, I receive the following error:

Traceback (most recent call last):
File "C:\Program Files\Google\google_appengine\lib\webapp2-2.5.2\webapp2.py", line 1535, in call

DistributionNotFound: sendgrid

Thanks for your help!

EDIT: I have tried upgrading and re-installing pip and setuptools, also installing distribute and distribution. Nothing worked. I have searched through the web for similar errors, whether from distributionnotfound or from pkg_resource and nothing.

EDIT 2: Instead of installing with 'pip install sendgrid', I removed sendgrid and downloaded by zip from github sendgrid-python, then running setup.py. Initially the results were the same, sendgrid works from shell, but not from GAE. However, the zip download includes a DIST folder, which if copied into the GAE directory along with the sendgrid folder, removes the DistributionNotFound error. BUT, no mail is sent from the GAE project.

Thanks, hope someone has an answer.

Thanks to the guys at sendgrid-python this issue is resolved, with an update to sendgrid-python.

4 steps:

• 'pip install sendgrid'
• 'pip install smtpapi'
• copy sendgrid folder and smtpapi folder into your GAE directory
• move smtpapi folder into sendgrid folder - example code from github sendgrid-python now executes correctly and how you have sendgrid functionality for GAE.

Hope this helps someone.
