python - 从 google.cloud.logging_v2 导入类型 ImportError : cannot import name types

Question

我正在开发一个在 GAE 上运行的小应用程序。当我部署我的应用程序或尝试使用 virtualenv(根据文档)时，当我尝试访问该应用程序时，我在 Cloud Platform 的日志中看到以下内容(它们在本地也相同):

File "/base/data/home/apps/d~my-project/gen-debug:413039252702584887/main.py", line 10, in <module>
    from google.cloud import logging_v2
File "/base/data/home/apps/d~my-project/gen-debug:413039252702584887/lib/google/cloud/logging_v2/__init__.py", line 17, in <module>
    from google.cloud.logging_v2 import types
ImportError: cannot import name types

我抛出此错误的代码如下所示:

from google.cloud import logging_v2
client = logging_v2.LoggingServiceV2Client()
c = client.list_log_entries(["my-project"], filter_='resource.type="global" AND jsonPayload.hello="there"')
l = list(c)
l1 = l[0]
desc, value = l1.ListFields()[1]
print desc.camelcase_name, dict(value.items())

非常奇怪的是，在 Google 中，我可以进入 Cloud Shell session ，进入 ipython，并且这段代码完全有效。

...: l1 = l[0]
...: desc, value = l1.ListFields()[1]
...: print desc.camelcase_name, dict(value.items())
...: 
jsonPayload {u'hello': u'there'}

在 GAE 上运行它与在 Google Cloud Shell 上运行它有何不同？这个导入错误似乎是 Google 的问题，但我不确定。

这看起来像通用的 python client for Stackdriver logging .这不是为 GAE 第一代(即 Python 2.7)应用程序设计/支持的，因为此运行时已经集成了自己的(定制的)stackdriver 日志记录。

来自 Supported environments :

The following VM instances support Stackdriver Logging using their own software, possibly including custom versions or configurations of the Stackdriver Logging agent. Manually installing the Stackdriver Logging agent on them is not supported:

• App Engine standard environment VM instances. App Engine includes built-in support for Stackdriver Logging. For more information, see Stackdriver Logging in App Engine Apps.

• App Engine flexible environment VM instances. Apps running in the App Engine flexible environment can write logs that are in addition to what is included in the App Engine standard environment. For more information, see Stackdriver Logging and the App Engine flexible environment.
