Remove ImportError of Module for Sublime Text

Gists When I launched Sublime Text, I noticed that the error occurred. The error is as follows. ImportError: No module named 'yaml' I confirmed that this error occurs when the plugin of Material Theme is read. And the error started to occur after Material Theme was updated, recently. In this report, I would like to introduce the method for removing this error. The flow is as follows. Download a file including library for yaml (PyYAML) from https://pypi.
