virtualenv: cannot access lib: No such virtualenv or site directory

I am using Google Cloud Platform to create a Django based http API, which uses Google's cloud SQL API and Machine Learning API.

I made a django-mysql app on my pc and is able to test it successfully on localhost. I want to deploy this app to Google Cloud.

Following are my relevant files: app.yaml:-

runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /static
  static_dir: static/
- url: .*
  script: mysite.wsgi.application

libraries:
- name: MySQLdb
  version: 1.2.5
- name: numpy
  version: "1.6.1"


skip_files:
- ^(.*/)?- ^(.*/)?.*~$
- ^(.*/)?.*\.py[co]$
- ^(.*/)?.*/RCS/.*$
- ^(.*/)?\..*$
- ^env/.*$

appengine_config.py:-

from google.appengine.ext import vendor
import os
vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))

I am getting a 500 error on api home. here. I am getting the following error report on my dashboard:-

Traceback (most recent call last):
  File "/base/data/home/runtimes/python27_experiment/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle

ValueError: virtualenv: cannot access lib: No such virtualenv or site directory

Originally the appengine_config.py contained:-

from google.appengine.ext import vendor

vendor.add('lib')

As suggested here, I changed it to the current file.

I deploy my project using gcloud app deploy. I do not understand how to use gcloud_sql_proxy for deploying.

I am for sure having a lib folder in same directory as app.yaml. I do not know what I am doing wrong. Any help or suggestion is appreciated.

The prior configuration as mentioned here seems to be correct. And as shown in this sample app, try installing dependencies with pip:

pip install -t lib -r requirements.txt
