It looks like the App Engine SDK is not installed, or at least the Python runtime cannot find it.

Try:
尝试：
import google
print google.__path__
to see what exactly you're importing.
看看你到底要导入什么。

import sys
sys.path.insert(1, '/Users/<username>/google-cloud-sdk/platform/google_appengine')
sys.path.insert(1, '/Users/<username>/google-cloud-sdk/platform/google_appengine/lib/yaml/lib')
sys.path.insert(1, 'lib')
if 'google' in sys.modules:
del sys.modules['google']
this solves the problems for me
这为我解决了问题

I had this same issue because I pip installed gcloud before downloading and installing the SDK. The pip install created a python package google which didn't contain the appengine submodule (which is found in the SDK folder). I uninstalled the gcloud and related packages. Then just pip installed the google-cloud-bigquery which is the only package I needed from gcloud. Everything works fine now.
我遇到了同样的问题，因为我在下载和安装 SDK 之前安装了 gcloud。pip 安装创建了一个 python 包 google，其中不包含 appengine 子模块（可在 SDK 文件夹中找到）。我卸载了 gcloud 和相关软件包。然后 pip 安装了 google-cloud-bigquery，这是我从 gcloud 中需要的唯一软件包。现在一切正常。

check if you named some file google.py :) in the same package, because this can shadow the import of google.appengine.ext. I had the same error:
检查您是否在同一个包中命名了某个文件 google.py :)，因为这会影响 google.appengine.ext 的导入。我有同样的错误：
python import error “No module named appengine.ext”
and deleteting the file solved the problem.
并删除文件解决了问题。

First possible reason:
第一个可能的原因：
you don't install the python library in google cloud sdk, so you can run in cmd (as administrator):
你没有在google cloud sdk中安装python库，所以你可以在cmd中运行（以管理员身份）：
gcloud components install app-engine-python.
gcloud components install app-engine-python.
Second possible reason:
第二个可能的原因：
your IDE is not success get into google libraries, they exist in:
你的 IDE 没有成功进入谷歌库，它们存在于：
C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine
C:\Program Files (x86)\Google\Cloud SDK\google-cloud-sdk\platform\google_appengine
or in:
