Dependencies not installing from lib directory in google app engine - google-app-engine

Question

As far as I can tell, I have set up my flask app right. lib, containing all dependencies is at my root, and contains what Requirements.txt has in it. my appengine_config.py contains the below
print 'running app config yaya!'
from google.appengine.ext import vendor
import os
import sys
print os.path
print os.path.realpath
print os.path.realpath(__file__)
print os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib')
sys.path.insert(0,'./lib')
vendor.add('lib')
print 'I am the line after adding lib, it should have worked'
per all those print statements, nothing is erroring, but I am getting
No module named flask_sqlalchemy
after deploying and seeing a 500. What am I missing to get these suckers installed?
EDIT---------------
thanks and here --
running app config yaya!

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
Not sure if it is related, but I am also getting https://code.google.com/p/google-cloud-sdk/issues/detail?id=729
but that fix doesnt help

I moved everything from /site_pakcages up a dir to /lib and I am alot closer, some of my pages are even working! but now I get
ImportError: No module named _sqlite3
but the code reads
except ImportError as e:
try:
from sqlite3 import dbapi2 as sqlite # try 2.5+ stdlib name.
except ImportError as ee:
raise ee
return sqlite
why would there be an underscore in the import attempt here? help?

tldr: use appengine_config.py and copy your virtualenv to a folder called lib, then make SURE you are running the app via dev_appserver.py
(the below is via bash in ubuntu) SO after a long battle, I find that virtual env and gcloud dont play nice -
I copied everything from my virtual env dir
.../.virtualenvs/nimble/local/lib/python2.7/site-packages
into
[projectdir]/lib
and my appengine_config.py finally worked locally like it does in the cloud, but I absolutely HAVE to run
dev_appserver.py [my proj dir here]
or the google.appengine module wont load. did not know I should be using dev server. I feel very dumb.
for reference, heres the appengine_config.py
"""`appengine_config` gets loaded when starting a new application instance."""
print 'running app config yaya!'
from google.appengine.ext import vendor
vendor.add('lib')
print 'I am the line after adding lib, it should have worked'
import os
print os.getcwd()
