Python 2.7 &引用；TypeError:无法连接'；str'；和'；非类型'；“对象”；Python中的Google Adwords API客户端

我无法将下载报告功能用于Python客户端。我在v201306中使用adwords-15.9.0。它总是在以下情况下失败：

$ ./classifications.py 
Traceback (most recent call last):
  File "./classifications.py", line 48, in <module>

您的身份验证有问题，如

OAuth2Credentials

对象的属性

access\u-token

为

None

所示

如果您还没有，请看一看示例，了解如何处理通过OAuth2进行的身份验证。您还需要创建一个应用程序来获取客户端ID和密码

是的。已在v15.9.1中修复
