Did exactly the same as here

Answer 1

Problem with rigger plugin

Answer 2

There must be no spaces at the end of the include
//= template/tabs.html

Answer 3

It is also possible that some js file is missing (as an option, you need to do a bower update).

Answer 4

Most likely, the problem is in the work of Rigger when building js.
Remove all js files except for main.js in a separate folder.
The result should be:

src/
-- js/
-- -- main.js
-- -- plugins/
-- -- customize/
-- -- etc/

Answer 5

This is not a gulp file error, the exception comes from the root of the gulpa installation.

Answer 6

It is also possible that there are spaces in the path to your project in the folder names or in the files themselves.
/Users/User/Documents/work/portfolio Df/ - I got an error because of this
/Users/User/Documents/work/portfolioDf/

Answer 7

3 situations in which such an error occurs:
- The file extension is different from the one you are connecting the file
to - There are empty characters at the end of the path (I puzzled for a very long time when I was looking :) )
- Wrong path
