How to fix “AttributeError: 'module' object has no attribute 'SOL_UDP'” error in Python Connector Mule

问题

I'm trying to execute a basic script to return Cisco Config File as a JSON Format, and I have a success process over Python2.7.16 and Python 3.7.3, but when I'm trying to execute the same script over Python Connector for Mule ESB I receive the error refered in the title of this thread.

This is for a Mule feature, the Python connector script in this tool, works with a Jython 2.7.1, and is loaded as a library for the Mule.

I expect the output as a JSON file but actual output is:

Root Exception stack trace:
Traceback (most recent call last):

  File "C:\Python27\Lib\site-packages\ciscoconfparse\__init__.py", line 1, in <module>

The only thing I had to do was comment that line in the script resolver.py and in this way the script on Anypoint Studio ran smoothly.

Thanks for your help, I hope that this helps to other people.

The problem appears to be that you are trying to execute a script that depends on a different python package. Mule supports executing python scripts using the Java Jython implementation but it probably doesn't know about pyhton packages dependencies.
