Ruby on Rails

You are mixing webpack with yarn. The only use of yarn is to download javascript packages from https://yarnpkg.com/lang/en/ to your app's node_modules folder. Webpacker is a gem that uses Webpack which is an assets manager/packer solution similar (but with conceptually different approach) to Sprockets (known as the rails' assets pipeline). Both Webpack and Sprockets can use the node_modules folder to find the required files.
You can use webpacker or sprockets on rails projects, you can even use both at the same time, the only difference between rails 5 and 6 is that 5 defaults to sprockets and 6 defaults to webpacker for new projects. You don't have to migrate to webpack if you don't want to, you should be able to upgrade to rails 6 without using webpack and everything should work as before.
Yarn won't create the /packs folder, webpacker should do that, maybe you didn't configure webpacker correctly or you didn't run the webpacker compiler. I suggest you follow the official webpacker guide to understand it https://github.com/rails/webpacker#installation

Also the assets pipeline still works the same way with rails 6, only webpacker is the default now, but you can keep the old behaviourEl lun., 14 oct. 2019 19:44, fugee ohu <fuge...@gmail.com> escribió:to upgrade an app to rails 6 i should run `yarn add <requirement>' for everything that was listing as "//= require <requirement>" ?--

Webpacker::Manifest::MissingEntryError error? Because the manifest file isn't found?
