Python 2.7 Windows本地appengine用法：oauth2client ImportError

我正在使用App Engine Standard，开发一个Python后端服务，在某个时候，我告诉自己：

“嘿，为什么不在使用远程数据存储时在本地尝试运行服务器？”

我可以在本地运行这段代码，但我不明白为什么远程api存根会抛出错误：

“文件”C:\ProgramFiles（x86）\Google\Cloud SDK\google cloud SDK\platform\google\u appengine\google\appengine\ext\remote\u api\remote\u api\u stub.py“， 第1003行，在ConfigureRemoteApiForOAuth'oauth2client模块：%s'中 （e）

ImportError：使用OAuth凭据需要oauth2client 模块：没有名为oauth2client的模块”

尽管如此，根据pip的说法，我已经安装了oauth2client（当我运行

pip安装时，我看到了这一点——升级oauth2client

提前感谢您的帮助

编辑：

我的问题不是重复的。我确实在lib文件夹中安装了google api客户端，并确保“appengine_config.py”文件与必要的行一起放置到位

它仍然没有解决我的问题，所以我将提供更多的细节

这是my main.py（负责GAE的默认服务）或至少是它的一个脱脂版本：

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，会出现以下错误：

我希望这是更多的解释。再次感谢您的帮助提前

解决方案：（感谢@Dan Cornilescu）

=>永远不要忘记“导入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），我一开始就把它们弄丢了，而我认为我一切都做对了

---

然而，我还没有完成，我正面临一个新问题，我将在一个新问题中键入它，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）。[如果你对新问题感到好奇，它会]

将相关评论转换为答案

您显示的代码段似乎缺少示例中明显需要的设置部分：

---

如果有关系，请不要这样做，但该示例还显示了一个

dev\u appserver.fix\u sys\u path（）

你没有。那是因为我在复制粘贴到我的问题时错过了它，谢谢你指出了这一点。我相应地编辑了。没有：/I抱歉@DanCornilescu和snakecharmerb我完全错过了你的答案。我根据解决方案更新了我的问题（一段非常愚蠢的代码丢失）

try:
    import dev_appserver
    dev_appserver.fix_sys_path()
except ImportError:
    print('Please make sure the App Engine SDK is in your PYTHONPATH.')
    raise
