Debian升级后找不到扭曲插件

Question

After I upgraded from debian jessie to stretch, twistd does not find my plugin anymore. I could not find what's wrong. I guess I need to specify some path now which wasn't neccessary before or similar.

I get the error /usr/bin/twistd: Unknown command: otfbot and in the list of Commands, the two commands of the software are not listed anymore. The directory structure of the plugins for twisted is

twisted/plugins/genconfig_plugin.py
twisted/plugins/otfbot_plugin.py

And both instantiate a ServiceMaker.

Twisted 16.4 removed the feature of twistd (and trial and all other Twisted command line scripts) which caused it to add the current working directory to sys.path . If you were relying on your working directory to allow your code to be found when using a version of Twisted older than 16.4 (Debian Jessie includes 14.0.2) and you've upgraded to version 16.4 or newer (Debian Stretch includes 16.6.0) , you must now explicitly add the desired directories to the import path yourself, perhaps by setting up a virtualenv or by setting PYTHONPATH directly.

This was an accidental change and is not documented in the release notes (despite the clear, confusing user-facing consequences).
