如何解决“导入错误：没有名为 google.auth 的模块”？

Question

我正在通过 dev_appserver 在本地运行标准的应用引擎环境，无法摆脱以下错误：

导入错误：没有名为 google.auth 的模块

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，如图pip show google.auth所示：

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 t——但没有结果。

我不太确定接下来要采取什么措施来调试这个问题。这里的任何人都可以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：

位置：/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 - 请注意您应该遵循的复制第三方库-t lib/过程中的 pip 选项：

2. 使用带有标志的pip（版本 6 或更高版本）-t <directory>将库复制到您在上一步中创建的文件夹中。例如：

   pip install -t lib/ <library_name>
