I am migrating from python27 to python37. I have ported the python2 code to python3 code. The problem is when i try to run the development server, it says ModuleNotFoundError: No module named 'google.appengine'. I have the google cloud sdk downloaded.
I also have the following google libaries downloaded:
google==2.03; google-api-core==1.17.0; google-auth==1.14.3; google-cloud==0.34.0; google-cloud-core==1.3.0; google-cloud-datastore==1.120; google-cloud-ndb==1.2.0; google-cloud-storage==1.28.0;
I am using the CLOUD_DATASTORE. Does this have anything to do with that? Do i have to migrate?
Here is the full error:

ModuleNotFoundError: No module named 'google.appengine'
The google.appengine module is baked into the first-generation Python (2.7) runtime. It's not available to install via pip, in the second-generation (3.7) runtime, or in any Docker environment.
The only way to use it is by writing and deploying a first-generation App Engine app.
Depending on what you're doing, you should be able to replace it with a client library call instead.
See https://cloud.google.com/appengine/docs/standard/python/migrate-to-python3 for more details.
