Bootstrap 4.6.2 popper issue

[helmutrs]

Ruby 3.1.3
Rails 7.0.4.3

using import maps and sprockets (without nodejs).

gem 'bootstrap', '~> 4.6', '>= 4.6.2'

there is an issue with popper: undefined is not an object (evaluating 'e.Popper=t()')

when change to bootstrap 5v, the issue disappear. (same config just different gem version)

config/importmap.rb
pin 'popper', to: 'popper.js', preload: true
pin 'bootstrap', to: 'bootstrap.min.js', preload: true

app/assets/stylesheets/application.scss

@import 'bootstrap';

app/javascript/application.js:

//= require jquery3
//= require popper
//= require bootstrap

I also met this problem. Has it been solved?

I was seeing the same Popper JS error and noticed that my project was loading Bootstrap 5 instead of 4, regardless of my //= require bootstrap. It turns out there was a lingering bootstrap npm package in my node_modules folder that is also including in the asset paths, this was trumping this gem's assets because of the order of load.

Hopefully this information helps others!

Also seeing this issue, did anyone find a fix?

I was able to work around this bug by using the bundled JS version of Bootstrap (bootstrap.bundle.min.js) this file includes Popper but not JQuery.

Gemfile

gem 'bootstrap', '~> 4.6.2'  # Used for SCSS 

application.scss

@import 'boostrap';

Importmap

pin 'jquery', to: 'jquery3.min.js', preload: true
pin 'bootstrap', to: 'https://cdn.jsdelivr.net/npm/bootstrap@4.6.2/dist/js/bootstrap.bundle.min.js', preload: true

asset.rb

Rails.application.config.assets.precompile += [
  'jquery3.min.js',
  'bootstrap.bundle.min.js'
]

application.js

import 'jquery';
import 'bootstrap';

Hope this helps!
