I had the default Bootstrap “v4.0.0-beta” installed, and working.
I did this:
bower uninstall bootstrap --save
Then I did this:
bower install bootstrap --save
Here’s the output of the install operation.
Then, now if I try to run gulp, I get these errors.
How do I fix this. Why does this happen?
I have a full folder backup of the theme before I did this (except node_modules).
