python - 如何解决 "ImportError: No module named google.auth"？

Question

我通过 dev_appserver 在本地运行标准应用引擎环境，但无法消除以下错误:

ImportError: No module named google.auth

完整追溯(用 ... 替换个人详细信息):

Traceback (most recent call last):
  File "/Users/.../google-cloud-sdk/platform/google_appengine/google/appengine/runtime/wsgi.py", line 240, in Handle
    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())

    raise ImportError('No module named %s' % fullname)
ImportError: No module named google.auth

我确实安装了 google.auth，如 pip show google.auth 显示:

Name: google-auth
Version: 1.6.3
Summary: Google Authentication Library
Home-page: https://github.com/GoogleCloudPlatform/google-auth-library-python
Author: Google Cloud Platform
Author-email: jonwayne+google-auth@google.com
License: Apache 2.0
Location: /Users/.../Library/Python/2.7/lib/python/site-packages
Requires: rsa, pyasn1-modules, cachetools, six
Required-by: googleads, google-auth-oauthlib, google-auth-httplib2, google-api-python-client

我已经升级了所有需要 google.auth 的模块 - googleads、google-auth-oauthlib、google-auth-httplib2、google-api-python-clien - 但没有结果。

我不太确定下一步要采取什么措施来调试此问题。这里有人能指出我正确的方向吗？

Answer 1

您的google.auth安装在系统的Python站点包中，而不是在您的应用程序中:

Location: /Users/.../Library/Python/2.7/lib/python/site-packages

您需要在应用程序中安装应用程序的 python 依赖项 - 请注意 -t lib/ Copying a third-party library 中的 pip 选项您应该遵循的程序:

2. Use pip (version 6 or later) with the -t <directory> flag to copy the libraries into the folder you created in the previous step. For example:

   pip install -t lib/ <library_name>
