ImportError：没有名为内置模块的模块-Google App Engine标准-Django-Python 2.7

Question

I'm trying to deploy an application and this error keeps coming up. I am using the commands below in my views/models/form/settings.py, in order to use the same code I did for Python 3.

from __future__ import absolute_import, division, print_function
from builtins import (bytes, str, open, super, range,
                  zip, round, input, int, pow, object)

I've already installed the library:future==0.16.0 on my requirements-vendor.txt

On localhost I can run it, using a Conda Env (python 2.7) but the deployment on GAE(standard) I got the 500 Server Error.

Answer 1

App Engine Standard does not actually depends on a requirements.txt file for using third-party libraries, that's the case for App Engine Flexbile

If you want to use a third-party library which is not in the list of already built-in libraries ( this list ) ,as in this case is future , you need to follow the Using third-party libraries for App Engine Standard docs , which was mentioned by @snakecharmerb. Do the following n the same folder where you have your app.yaml file:

1. Create a directory where your third-party-libraries will be stored:

   mkdir lib

2. Install library on the created folder:

   pip install -t lib future==0.16.0

3. Create file named appengine_config.py and add the following two lines to the file:

   from google.appengine.ext import vendor

   vendor.add('lib')
