【问题描述】：
今天去处理一个较旧的 Python2.7 AppEngine Standard 项目，但我似乎无法让 Endpoints 工作。我下载了示例代码以查看我的项目是否是罪魁祸首，但该示例也不起作用。 https://cloud.google.com/endpoints/docs/frameworks/python/get-started-frameworks-python#run_local
dev_appserver.py --host 192.168.1.73 app.yaml --smtp_host=smtp.telus.net --smtp_port=25
INFO 2020-02-04 19:46:38,243 devappserver2.py:289] Skipping SDK update check.

一切都开始好了，但是当我到达端点时：/_ah/api/echo/v1/echo

这是否与 2020 年 1 月 1 日取消对 python2.7 的支持有关？作为记录，我的应用在 Appengine 上仍然可以正常运行，但我无法再进行开发了。
[编辑]谷歌云版本：
Google Cloud SDK 279.0.0
alpha 2020.01.31
app-engine-python 1.9.88
app-engine-python-extras 1.9.88
[编辑] Python：
Python 2.7.17 (default, Nov 7 2019, 10:07:09)
[GCC 7.4.0] on linux2
如果我迁移到 Python 3，那么我会丢失端点，我需要完全重写我的客户端代码。
提前致谢。

在我看来，根本原因与此有关：github.com/eventlet/eventlet/issues/401 我相信它是由 eventlet 引起的，它在开始时与 Python 混淆了很多。正如我从您的日志中看到的那样，可能 monotonic.py 正在幕后导入 eventlet。您可以尝试此处提到的解决方法：stackoverflow.com/questions/48925318/…

您能否更新问题，提供更多关于您的操作系统、运行时环境等的信息？
