After upgrading to Google Cloud SDK version 184.0.0, I started to get this error whenever trying to access my app's URLs - "ImportError: No module named ipaddr".

The full log looked like this...
INFO 2018-01-15 06:55:09,031 devappserver2.py:105] Skipping SDK update check.

import ipaddr
ImportError: No module named ipaddr

Running `gcloud version` gave these results...
 gcloud version
Google Cloud SDK 184.0.0
app-engine-python 1.9.65
beta 2017.09.15
bq 2.0.28
core 2018.01.05
gsutil 4.28

As the error suggested the ipaddr module file was missing from the google-cloud-sdk/platform/google_appengine directory. The fix was to get a copy of this file from google's GitHub repository manually.

I used downloaded the file from this location.
wget https://raw.githubusercontent.com/google/ipaddr-py/master/ipaddr.py

Then I moved the file to the google-cloud-sdk/platform/google_appengine directory...
mv ipaddr.py google-cloud-sdk/platform/google_appengine/ipaddr.py

Once the file was in place and the dev server was restarted, the error went away and I could start testing my app again.
