Ruby on Rails Bootstrap undefined method `start_with?' for /bootstrap\/glyphicons-halflings-regular\.(?:eot|svg|ttf|woff)$/:Regexp

Question

First of all, good forum to all. I'm trying to make a simple forum site with Ruby on Rails and I decided to use bootstrap as a css library and I successfully installed it.

However, although there is no error in the installation, when I go to the required route, I get the following error: Error-1

Console Error:

Thank you in advance to my teachers who will help.

did you config assets.precompile with a Regex ?, it looks like [Sprockets 3+ deprecated precompile filters such as regexps and procs](https://github.com/rails/sprockets-rails/issues/269) — Lam Phan, Dec 20 '21 at 03:29
