python - Creating a lib directory in Google App Engine and adding it to sys.path -

i'm writing google app engine project in python flask. here's directory construction hello, world! app (contents of 3rd party libraries ommitted brevity's sake):

project_root/ flask/ jinja2/ markupsafe/ myapp/ __init__.py simplejson/ werkzeug/ app.yaml itsdangerous.py main.py

here's main.py:

from google.appengine.ext.webapp.util import run_wsigi_app myapp import app run_wsgi_app(app)

and myapp/__init__.py:

from flask import flask app = flask("myapp") @app.route("/") def hello(): homecoming "hello, world!"

since flask has many dependencies , sub dependencies, thought nice tidy directory construction putting 3rd party code in subdirectory (say project_root/lib). of course, sys.path doesn't know find libraries.

i've tried solutions in how modify sys.path in google app engine (python)?, doesn't seem work. i've tried changing from flask import flask from lib/flask import flask, no avail. there way this?

look @ defining path manipulation in appengine_config.py means path manipulation has performed once.

then move 3rd party files in lib per suggestion. utilize relative path 'lib' either specifying sys.path

sys.path.insert(0,'./lib')

or use

import site site.addsitedir("./lib")

do not utilize absolute paths, won't same when deploy code.

putting lib first can useful, if don't want google supplied version of webob.

python google-app-engine sys.path
