I had a similar issue, but was able to solve it. I had a package named email.py that broke urllib. When their http client is importing other modules, if it fails to import urllib, it has an exception to import urllib2 (for backwards compatibility with Python 2).

Go to these lines in the http client code, and remove the try/except just leaving the Python 3 import statements.

import urllib.request as urllib
from urllib.parse import urlencode
from urllib.error import HTTPError

That will tell you where your error actually is and why it isn't successfully importing.

Thanks @isaacnicholas!

@chenzhendong,

Have you tried @isaacnicholas' suggestion?

I ran into this issue myself. I also had an file named 'email.py' so I renamed it, uninstall sendgrid and reinstalled. Everything worked after that.
