Installs via Sketch Toolbox do not work
I guess having a same name with other plugin wasn't the problem, still it doesn't work when I install the plugin with Sketch Toolbox. It gives these errors on console when I try to toggle toolbox:

I tried to restart the Sketch but didn't work. It works when I install it by downloading it from here and double clicking.
