Sprockets::FileNotFound: couldn't find file 'jquery.ui.all' on Rails 4 - rake

Question

Sprockets::FileNotFound: couldn't find file 'jquery.ui.all'
I attempted all recommendations found so far.
None of them works for me.
I cannot run anymore the program in development and as such I cannot anymore make a new deployment online.

Answer 1

I ran into a similar issue and it turned out that at some point they started using jquery-ui instead of jquery.ui and there is no need to have the all part anymore
//= require jquery-ui
See the section titled Require Specific Modules on the jquery-ui-rails page for more information.

I found the problem. When integrating bootstrap with data tables when changes are introduced in files and folder names in both sides, nothing works anymore. So I separated them, I am using bootstrap for buttons and menus and data tables html style, no bootstrap integration and work perfectly, fast and smooth. Looks like these these folks can't keep up with each other.
