I wanted to add a google.cloud.storage dependency to my project so I tried to install this dependency with
pip install --upgrade google-cloud-storage
Running my app again with dev_appserver, it shows me that my gcloud components needed to be updated. Ok so, gcloud components update
And in my src/__init__.py file, I got the code that tells gcloud in which folder to look for dependencies like this:
from google.appengine.ext import vendor
vendor.add('src/libs')
All the dependencies are installed correctly, except that I'm getting the error ImportError: No module named google.oauth2
PS: My app is using OAuth2 to secure access to the API. And it was working correctly before I do a components update, now even if I rollback code, remove the libs folder and install again dependencies, I still got the No module error, and it seems like dev_appserver is not looking for that dependency inside the libs folder !
Here's the result of gcloud --version:
Google Cloud SDK 188.0.1
app-engine-python 1.9.66
app-engine-python-extras 1.9.63
bq 2.0.28
core 2018.02.08
gsutil 4.28
And here's the Traceback:

I've had this issue quite a bit. I uninstalled all Google packages from my local machine, deleted the lib folder in my GAE app folder, created it again then executed:
pip install -t lib google-auth google-auth-httplib2 google-api-python-client --upgrade
That should fix your problem.
EDIT: I think you never get this error if you use something like virtualenv.
The problem was coming from the dependencies being installed in both the project folder (in the src/libs folder), and in the python local libs folder (/usr/local/python2.7/dist-packages). I removed the google libraries from the python libs folder and it's now working again !
Just upgrading some python packages solved my issue:
pip install --upgrade google-auth google-auth-httplib2 google-api-python-client
