I have these errors in a Rails 6 app and all javascript is not working:

<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
It was working ok, but I don´t know when and why it left working.
Could someone help me?
Sorry, I solved it yet. Previously to having the error, I installed yarn autoclean, and I discovered later that in .yarnclean there was this:
# asset directories
docs
doc
website
images
assets
I removed this, and error disappeared.
Run the commands. the node_modules has a problem i guess.
yarn add rails-ujs turbolinks
npm install rails-ujs turbolinks
Encountered this error when running system tests and managed to fix it by removing node_modules folder and anything that was cached in /tmp folder and then reran yarn install.
Cause of the issue for me was:
Had recently ran yarn autoclean --init yarn autoclean --force and then tried to reverse it since everything was messed up.

Trying to isolate an error I'm getting with the basic setup of a new blog site using the below just so I can test Action_Text for the create blog section.
Every-time i create the below- it works great until i change the <%= form.text_area :content %> to <%= form.rich_text_area :content %> then the text area vanishes????
package.json

Rails db:migrate
Rails action_text:install

end
<%= form.rich_text_area :content %>
I have searched for days online, tested, broken this multiple times and still cant find a solution.
Any assistance would be great.
Thank you
I am trying to install this theme - Cleopatra - built on Tailwind CSS in my Rails 6 app, but I can't quite make heads & tails of how to do it properly with webpacker.
I am sure this should be fairly straightforward, but I don't use any JS frameworks so I don't quite get webpacker and JS package managers other than knowing they are similar to Bundler and Gemfiles.
I have Tailwind CSS successfully installed, and I have tried a variety of things and all generate errors or don't render successfully.
So I would rather just a step by step approach to installing it.
I am using Rails 6.0.3.6 and Ruby 3.0.1p64.

This is my app/javascript/packs/application.js:
const images = require.context('../img', true)
const imagePath = (name) => images(name, true)
import "../packs/cleopatra";
import "../stylesheets/application.scss";
// import "apexcharts";
import ApexCharts from 'apexcharts';
window.ApexCharts = ApexCharts; // return apex chart
This is my postcss.config.js:
module.exports = {
plugins: [
require('tailwindcss'),
require('autoprefixer'),
require('apexcharts'),
require('postcss-import'),
require('postcss-flexbugs-fixes'),
require('postcss-preset-env')({
autoprefixer: {
flexbox: 'no-2009'
},
stage: 3
})
]
}
This is my app/javascript/stylesheets/application.scss:
#import "tailwindcss/base";
#import "tailwindcss/components";
#import "tailwindcss/utilities";
#import "cleopatra";
I have added apexcharts via yarn.
Both of my custom files are app/javascript/stylesheets/cleopatra.css and app/javascript/packs/cleopatra.js.
This is in my application.html.erb:
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= stylesheet_pack_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
Edit 2
I am using webpacker 4.3.0, and you can see what packs/cleopatra.js looks like here.
Steps:
cloned cleopatra theme repo locally
git clone https://github.com/moesaid/cleopatra.git moesaid_cleopatra
rails new s_67585007 --no-ri --no-rdoc
rails g controller home index
added root route in config/routes.rb
root 'home#index'
added tailwindcss package with requirements
yarn add tailwindcss#compat postcss#7 autoprefixer#9
postcss.config.js
module.exports = {
plugins: [
require('tailwindcss'),
require('autoprefixer'),
require('postcss-import'),
require('postcss-flexbugs-fixes'),
// require('apexcharts'),
require('postcss-preset-env')({
autoprefixer: {
flexbox: 'no-2009'
},
stage: 3
})
]
}

Climbing the learning curve with Webpacker and Rails 6.
I've installed Boostrap 4 using Yarn and Webpacker. When I try play with Bootstrap components in a browser's JS console then I get: TypeError: $.fn.button is undefined.
If I remove the Yarn installation add a Bootstrap CDN link in the head of the HTML (the old way) everything works fine. When I remove the CDN links and revert to using Webpacker I get back to the error above.
Here is my Webpacker setup:
// package.json
{
"name": "depot",
"private": true,
"dependencies": {
"#rails/actioncable": "^6.0.0-alpha",
"#rails/activestorage": "^6.0.0-alpha",

},

"devDependencies": {

}
}
// enviornment.js
const { environment } = require("#rails/webpacker");
const webpack = require("webpack");
environment.plugins.append(
"Provide",
new webpack.ProvidePlugin({

jQuery: 'jquery/src/jquery',
Popper: ["popper.js", "default"]
})
);
module.exports = environment;

Is there something I should be doing to export the Bootstrap functions to the global namespace?
Found a forum where this was discussed: https://gorails.com/forum/how-to-use-bootstrap-with-webpack-rails-discussion
They mentioned it could be caused by having jQuery loading multiple times, with the latest declaration preventing Bootstrap's JS from loading. I couldn't find any evidence of this in my project.
For me the fix ended up being a few lines added to the webpack entry point that exposed jQuery to the browser:
# packs/application.js
import JQuery from 'jquery';
window.$ = window.JQuery = JQuery;
I noticed even I removed require 'jquery' from applications.js, jquery still appears in the compiled application.js, so I removed this from enviroment.js
$: 'jquery/src/jquery',
jQuery: 'jquery/src/jquery',
and add this to application.js
import JQuery from 'jquery';
window.$ = window.JQuery = JQuery;
restart rails server, it works!

I'm currently developing with Rails5 and React.
And to use React, we use a gem called react-rails, and this gem uses webpacker.
At that time, in React, js.erb file was created to refer to the image precompiled with assets.
The information I looked up on the net had rails-erb-loader, so it should have been readable.
However, SyntaxError occurred.
I will write the details below.

After creating a new ruby 2.6 / rails6 app and
scaffolding the destroy popup is not working.
Any idea whats wrong.. happens out of sudden..

github.com/rails/webpacker/issues/2109,
solves the problem,
comment out //corejs: 3, in babel.config.js
Hopefully the bug will be solved soon.
For anyone that is as catastrophically dumb as I am with this Q/A as my only possible lead (that will take you nowhere) – My issue with Rails being undefined was that my javascript_include_tag was missing. In short, make sure you have:
<!-- app/views/layouts/application.html -->
<!-- turbolinks optional -->
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
