Question

在从github下载的示例目录中进行设置时可以正常工作，但是现在我已经构建了自己的API，开发服务器启动了，但是用CURL击中它时会抛出此错误：

$ dev_appserver.py ./app.yaml

但是python -m pip列表显示了这些：

google-endpoints 4.8.0
google-endpoints-api-management 1.11.0

开发服务器是否在其他环境下运行？它在其他示例文件夹中时正在工作，但不在此处。还有一个./lib文件夹，其中包含通过此命令安装的要求：

pip install --target lib --requirement requirements.txt --ignore-installed

其中当然包括端点...

$ gcloud version
Google Cloud SDK 237.0.0
app-engine-python 1.9.83
app-engine-python-extras 1.9.74
beta 2019.02.22
bq 2.0.42
cloud-datastore-emulator 2.1.0
core 2019.03.01
gsutil 4.37
kubectl 2019.03.01

这是main.py的（开头）：

# [START imports]
import endpoints
from endpoints import message_types
from endpoints import messages
from endpoints import remote
from datetime import datetime
# [END imports]

有趣的是，如果我输入python并尝试导入，则会收到其他错误：

$ python

>>> import endpoints

    from protorpc import message_types
ImportError: No module named protorpc
>>>

而python3则显示dev appserver所显示的相同错误。但是我看不到如何以python3的形式启动appengine服务器，因为app.yaml具有以下功能：

运行时：python27

Answer 1

缺少以下内容的appengine_config.py：

from google.appengine.ext import vendor

# Add any libraries installed in the `lib` folder.
vendor.add('lib')

ImportError：没有名为端点的模块
