Thanks for taking the time to report this issue. I'm sorry you're having problems.

I'm afraid we haven't had a chance to test and adapt this gem to the Webpacker way of managing assets. We'd be happy to consider a pull request that works for users using the traditional Sprockets asset pipeline, and the Webpacker assets pipeline.

+1 for getting this to work with webpacker.

I'd also love for this feature to be added! Thanks

Until this feature can be implemented, I've managed to get this gem to work with Rails 6 and Webpacker:

1. In config/webpacker.yml, under default, set the extract_css option from false to true.
2. Create the file app/javascript/packs/stylesheets.scss
3. Add the @import 'rails_bootstrap_forms'; line within this newly created stylesheets file.

I don't believe this messed up the rest of the application's CSS, but I haven't had the chance to fully test it yet.

Edit: Fixed typo in step one.

addisonmartin: I believe you mean "extract_css," not "extra_css." However, I still get the error: SassError: File to import not found or unreadable: rails_bootstrap_forms.

@addisonmartin 's trick worked for me. Yes @ThomasConnolly the option is extract_css, not extra_css.

Here is what finally worked for me: I cleared the buildpacks after learning they were not in the correct order. Here are docs from Heroku:

Verify that your buildpacks are set correctly and that Node comes before Ruby:

$ heroku buildpacks
=== myapp Buildpack URLs

1. heroku/nodejs
2. heroku/ruby$ heroku buildpacks:add heroku/ruby
   Verify that your buildpacks are set correctly and that Node comes before Ruby:

$ heroku buildpacks
=== myapp Buildpack URLs

1. heroku/nodejs
2. heroku/ruby

I also stopped precompiling my assets and let Heroku do that.
Now my app on heroku looks and acts exactly like my local app.

@addisonmartin Are you still adding the gem?

Implied yes, and I don't see anything in the node_modules that suggest it's installed otherwise.

What do you mean @MtnBiker? I did not open this issue, only posted a resolution to get the gem working with Rails 6.

To answer your question, I am still using the gem, and there is nothing to install that would appear in node_modules (I think).

[MtnBiker]

@addisonmartin. Thanks. The node_modules was a (rather obtuse) reference to what bootstrap has installed using Yarn and I had just looked to se if anything that looked like it related to forms.

The css is only a few lines, you can also just manually place in your webpacker scss/css also

.rails-bootstrap-forms-date-select select,
.rails-bootstrap-forms-time-select select,
.rails-bootstrap-forms-datetime-select select {
  display: inline-block;
  width: auto;
}

.rails-bootstrap-forms-error-summary {
  margin-top: 10px;
}

I came across the same issues plus the problem of bootstrap dropdown no longer working. Taking the workaround was showing the same error message. I then added the scss/css manually to app/javascript/stylesheets/application.scss. And now it was working and the dropdown works too.
Here the content of app/javascript/stylesheets/application.scss:

@import "~bootstrap/scss/bootstrap";
// @import "rails_bootstrap_forms";

.rails-bootstrap-forms-date-select select,
.rails-bootstrap-forms-time-select select,
.rails-bootstrap-forms-datetime-select select {
  display: inline-block;
  width: auto;
}

.rails-bootstrap-forms-error-summary {
  margin-top: 10px;
}

Unfortunately, it does not work:

I don't have a solution, but I understand that Webpacker cannot find this file. Because the file is out off scope of Webpacker.

I'm not sure if it can be related to this problem but I had a similar error using rails 7 and esbuild and I fixed it by doing the following import adding file extension ".css" into the file "project/app/assets/stylesheets/application.scss":

@import "rails_bootstrap_forms.css";
