Hi,

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](https://gist.github.com/arslanfarooq/f38c3e82ec3d7e4699c647736dff3c20) of the install operation.

Then, now if I try to run gulp, I get [these errors](https://gist.github.com/arslanfarooq/efcb81dbc3290189f4edfa02e7929e77).

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).
