KeyError 'pycodestyle'

[purpleP]

With my configuration I have KeyError 'pycodestyle' when pyls initializes configs.

I've fixed it by adding this

/home/michael/.venv/lib/python3.6/site-packages/pyls/config/config.py:94

        for source_name in reversed(sources):
            source = self._config_sources.get(source_name)
            if not source:
                continue

I can make a pull request If you someone explains to me how configuration works in language servers. I don't understand for example where should main lsp configbe. Should it be in ~/.settings.json or in ~/settings.json or somewhere in ~/.config?
