sublime无法高亮显示erb和haml文件的解决办法

>>> sublime.find_resources("HTML.sublime-settings")
['Packages/One Dark Material - Theme/prefs/Ext/HTML.sublime-settings']
Which is a theme I wasn't using, but rather:
"theme": "Cobalt2.sublime-theme",
"color_scheme": "Packages/Theme - Cobalt2/cobalt2.tmTheme",
I removed the One Dark Material package and now it shows:
>>> sublime.find_resources("HTML.sublime-settings")
[]

..and voila! Now working as expected. Opening an html.erb file sets the syntax to HTML (Rails).
