问题
I managed to make a Pyramid 1.2 WSGI app run on Google App Engine SDK 1.7. However, my current project uses several new Pyramid 1.3 features and I'm stuck on a WebOb version issue. Here's the error message:
VersionConflict: (WebOb 1.1.1 (/home/matt/Python/google_appengine/lib/webob_1_1_1), Requirement.parse('WebOb>=1.2dev')
Is there something I can do or I must wait for a new GAE release?
回答1:
A fairly reliable way to manage your pyramid application and it's dependencies on appengine is via the pyramid_appengine library which generates a skeleton project that uses buildout.
disclaimer: I wrote this as part of the pyramid sprint at pycon this year.

You can always bundle your own version of webob with your application:
In your application directory do:
wget http://pypi.python.org/packages/source/W/WebOb/WebOb-1.2.2.zip
unzip WebOb-1.2.2.zip
mv WebOb-1.2.2/webob .
rm -fR WebOb-1.2.2*
And redeploy your application.

I ended up modifying lib/python2.7/site-packages/pyramid-1.3.2-py2.7.egg/EGG-INFO/requires.txt in my virtualenv. I changed WebOb >= 1.2dev for WebOb >= 1.1.1 and it worked!
