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

Question

大家。

我是这个领域的新手。我使用 google 应用程序引擎使用 django 框架开发 Web 应用程序。我有一个关于 python lib 目录问题的问题... ImportError: no module named...

我的 appengine_config.py 文件是

# [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

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

安装

所以，我在我的项目中安装...但是..编译错误。

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

然而，如果我将我的 wanttousing_lib 移动到 ROOT 目录，它会起作用......

        to="TO_SENDER",

    )

也许，我是否将库列表添加到 app.yaml？喜欢

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

要求-vendor.txt文件是

Django==1.11.3

我该如何解决？请帮忙...

Answer 1

前一段时间我遇到过类似的问题，我没有使用 vendor.add('lib')，而是成功地这样做了：

vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))

我在第 4 步中找到了在 GAE 上使用第三方库的解决方案 here in the docs：

To copy a library into your project:
Create a directory to store your third-party libraries, such as lib/.
mkdir lib
Use pip (version 6 or later) with the -t flag to copy the libraries into the folder you created in the previous step. For example:
pip install -t lib/ <library_name>
(Using Homebrew Python on Mac OS X?)
Create a file named appengine_config.py in the same folder as your app.yaml file.
Edit the appengine_config.py file and provide your library directory to the vendor.add() method.
# appengine_config.py
from google.appengine.ext import vendor

# Add any libraries install in the "lib" folder.
vendor.add('lib')
The appengine_config.py file above assumes that the current working directory is where the lib folder is located. In some cases, such as unit tests, the current working directory can be different. To avoid errors, you can explicity pass in the full path to the lib folder using:
vendor.add(os.path.join(os.path.dirname(os.path.realpath(__file__)), 'lib'))

Answer 2

1) /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/...

2) /usr/local/lib/python2.7/...

我的项目指向 1)，但 pip install 指向 2)...

我尝试了 1) ./pip install twilio。所以，它有效！
