   Question:
   Follow the documentation below：
   https://pulsar.apache.org/docs/zh-CN/client-libraries-python/#installation-using-pip
   
   Under the condition of python V2.7, after using pip to install the pulsar library, the production and consumption scripts in the sample cannot be executed, and the prompt NameError: name 'ModuleNotFoundError' is not defined is displayed.
   In the same situation, there is no problem in python V3.6.
   The detail of error is refered to:
