无法导入appengine python模块

Question

On my local machine I am unable to import appengine.ext module.

I have set the path using the following code

>>> import sys
>>> sys.path.insert(1, '/usr/local/google_appengine')
>>> sys.path.insert(1, '/usr/local/google_appengine/lib/yaml/lib')

Here is the error

Answer 1

you should try to add the following code to the begining:

import dev_appserver
dev_appserver.fix_sys_path()

should work :).
