package-switch:create not working, errors in dev console

Using this package like it is described under "Usage" does not work, there is no menu showing up where the packages can be ignored/added/removed if I use Packages - Package Switch - Create Bundle from Atom's menu or package-switch:create in the Ctrl-Shift-P menu.

Looking at the "Toggle Developer Tools" - Console, there is an error:

Uncaught (in promise) Error: Could not find a file at path '/home/pemm/.atom/packages/package-switch/lib/../stylesheets/select-list.less'

And trying to use the package-switch:create command directly in the "Toggle Developer Tools" - Console returns: Uncaught SyntaxError: Unexpected token switch VM1162:1

Please help.
