我正在使用 App Engine Standard 开发 Python 后端服务，在某个时候，我告诉自己：
“嘿，为什么不尝试在使用远程数据存储时在本地运行服务器”
我可以在本地运行此代码，但我无法弄清楚为什么 remote_api_stub 会抛出错误：
“文件”C:\Program Files (x86)\Google\Cloud
SDK\google-cloud-sdk\platform\google_appengine\google\appengine\ext\remote_api\remote_api_stub.py",
第 1003 行，在ConfigureRemoteApiForOAuth 'oauth2client 模块：%s' %
e)
ImportError：使用 OAuth 凭据需要 oauth2client
模块：没有名为 oauth2client 的模块”
尽管根据 pip，我已经安装了 oauth2client （当我运行时我看到pip install --upgrade oauth2client
预先感谢您的帮助
EDIT:
我的问题不是重复的导入错误：没有名为 oauth2client 的模块 https://stackoverflow.com/questions/35663508/importerror-no-module-named-oauth2client。我确实在 lib 文件夹中安装了 google api 客户端，并确保“appengine_config.py”文件位于其位置并包含必要的行。
它仍然没有解决我的问题，所以我将提供更多详细信息！
这是我的 main.py （负责 GAE 的默认服务）或者至少是它的脱脂版本：
import os
import datetime
import dev_appserver
from google.appengine.ext.remote_api import remote_api_stub
from google.appengine.api import apiproxy_stub_map
dev_appserver.fix_sys_path()
local_urlfetch_stub = apiproxy_stub_map.apiproxy.GetStub('urlfetch')
def configure_remote_api_dev_safe (host):
if not os.getenv('SERVER_SOFTWARE', '').startswith('Google App Engine/'):
logging.info("running on local server")
remote_api_stub.ConfigureRemoteApiForOAuth(host, '/_ah/remote_api')
apiproxy_stub_map.apiproxy.ReplaceStub('urlfetch', local_urlfetch_stub)
else:
logging.info("running on remote server")
def configure_remote_api_dev_unsafe (host):
if not os.getenv('SERVER_SOFTWARE', '').startswith('Google App Engine/'):
remote_api_stub.ConfigureRemoteApiForOAuth(host, '/_ah/remote_api')
else:
logging.info("running on remote server")
class Main(webapp2.RequestHandler):
def post(self):
configure_remote_api_dev_safe ('{}.appspot.com'.format(app))
test = Test(createdAt=datetime.datetime.utcnow())
test.put()
self.response.write("done")
app = ndb.toplevel(webapp2.WSGIApplication({('/', Main)}, debug=True))
当我请求默认服务时出现此错误：

我希望这更具解释性。再次预先感谢您的帮助！
解决方案：（感谢@Dan Cornilescu）
=> 永远不要忘记“import dev_appserver”和对“dev_appserver.fix_sys_path()”的调用
由于代码版本控制（一个糟糕的选择），我一开始就失去了它们，而我认为我一切都是对的。
然而我还没有完成，我面临着一个新问题，我将在一个新问题中输入该问题，因为它与这个问题的原因无关（我希望在某个时候不会丢失任何其他内容）。 [如果您对新一期感到好奇，就在这儿 https://stackoverflow.com/questions/51443921/local-standard-app-engine-py-fails-auth-with-remote-datastore]
