I got this warning: "ctags: Warning: Ignoring non-option in /home/thu_nx/.ctags"
So I removed the empty line (num 12) and it worked

I found similar results to @hitamu. I deleted an 'empty' line and added another in its place. worked fine. Maybe a weird character?

Thank you!!! Here are mine (I have support for AngularJS directives, services, controllers, factories, modules and routes)

Thanks for the angular!

@andreicristianpetcu thanks! 👍

@philix, Hi. After adding the javascript configuration file to ctags. When a variable is Navigate to Definition, not only the variable declaration is searched, but also the use of the variable(as long as it is the same string, etc). How to solve?
