GAE 1.6 can not import module jinja2

[Kai]

I am trying my first python2.7 GAE apps. Everything goes smoothly in the GAE python2.7 Getting Started guild, except the chapter Using Templates.

http://code.google.com/appengine/docs/python/gettingstartedpython27/templates.html

I have added the lines in my app.yaml:

libraries:
- name: jinja2
  version: latest

I have also changed my helloworld.py to import jinja2 module.

And errors:

ERROR    2011-11-08 15:01:12,371 wsgi.py:170] 

Traceback (most recent call last):

How can I use jjinja2 template engine in the GAE 1.6 SDK?

Same here

Have you installed jinja2 locally? Historically, the SDK has not
included 3rd party libraries (PIL was the first example). They had to
be installed on your own machine, and the SDK would be able to import
them.

As Matt says, you need to install jinja2 on your local Python instance.

This will be fixed in a future release.

Thank you, Matt and Brian.
Actually, I have not installed jinja2 in my system. I will try to
fixed this minor issue and finish the tutorial guild. :)

How are we supposed to know this? I jumped into GAE with the 2.7
tutorial and there was no mention of installing packages locally. I
thought it was all bundled in GAE.

The fact that required pure-Python modules are not packaged with the
SDK is simply a bug. Installing it yourself is the work-around.

I did it.

I installed it locally and I am still unable to import jinja2, it is giving me the import jinja2 error every time.

[N. Rosencrantz]

If you do

import jinja2

you must download jinja2 and keep it in the app directory and it will work. The correct way of doing it however is to my knowledge

from webapp2_extras import jinja2

then you don't need the local library since you're importing from webapp2. It may depend on whether you want to use webapp2 or some other framework. I hope this works for you too.
