使用Google App Engine和Django将第三方库(twilio)添加到项目中

所有人.

我是这个领域的新手.我使用django框架使用Google App Engine开发Web应用程序.我对python lib dir问题有麻烦... ImportError:没有名为...的模块.

I'm a newbie in this field. I develops web application with google app engine using django framework. I have a troubleshot about python lib dir problem... ImportError: no module named...

我的appengine_config.py文件是

my appengine_config.py file is

# [START vendor]
from google.appengine.ext import vendor 

vendor.add('lib') # I believes this line is to add 'lib' folder to PATH.

# vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib')) # <-- and I tried too this line.

# [END vendor]

我的'requirements.txt'文件是

my 'requirements.txt' file is

MySQL-python==1.2.5 #app engine django project default
Django==1.11.3 #app engine django project default
django-twilio # add i want
twilio # add i want

，并且我使用pip install -t lib -r requirements.txt

所以，我安装了我的项目...但是..编译错误.

so, I installed in my project... but..compiled error.

from wanttousing_lib import example_module importError wanttousing_lib ..........

from wanttousing_lib import example_module importError wanttousing_lib..........

但是，如果我将我的wanttousing_lib移至ROOT dir，它就可以工作.....

however, if I move my wanttousing_lib to ROOT dir, it works.....

也许，我是否将库列表添加到app.yaml中? 喜欢

perhaps, Do I add library list to app.yaml ? like

libraries:
- name: MySQLdb
  version: 1.2.5
- name: twilio <-- like this
  version: -

requirement-vendor.txt文件为

requirement-vendor.txt file is

Django==1.11.3

我该如何解决?请帮忙...

how can i fix it? please help...
