Question

我正在Google App Engine标准环境Python 2.7中开发一个app-engine项目。主要是我的应用程序使用webapp2进行请求处理（WSGI协议）和jinja2作为python框架工作。

尝试导入google-cloud-bigquery，google-auth，google-oauth2时，我没有收到模块名称错误。

这些是迄今为止我尝试解决的解决方案，但其中任何一方都无法成功。

以上是[问题]：Google Cloud BigQuery Import not working in app engine project

第二个[问题]：Error importing Google Cloud Bigquery api module in python app

          query_results.run()
          rows = query_results.fetch_data()

app = webapp2.WSGIApplication(routes=[

if __name__ == '__main__':
main()

所有第三方库都使用pip安装在lib目录中。
