Following the “Getting Started with Rails” guide, after the " Let’s open
app/views/articles/index.html.erb , and replace its contents with:" step, clicking the http://localhost:3000/articles link results in what you see below. I got the same error on both an up-to-date Arch Linux system and a Mac running Catalina, both with the latest Ruby, Rails, Sqlite3, node.js. yarn installed. This is pretty astonishing/discouraging when the Getting Started guide’s first simple example blows up.
(I’m deleting some of the following because my first attempt to post this got the error “Sorry, new users can only have 5 links in a post”. This is going from bad to worse.)
Webpacker::Manifest::MissingEntryError in Articles#index
Showing /Users/dca/testit/app/views/layouts/application.html.erb where line #10 raised:
Webpacker can't find application.js in /Users/dca/testit/public/packs/manifest.json. Possible causes: 1. You want to set webpacker.yml value of compile to true for your environment unless you are using the `webpack -w` or the webpack-dev-server. 2. webpack has not yet re-run to reflect updates. 3. You have misconfigured Webpacker's config/webpacker.yml file. 4. Your webpack configuration is not creating a manifest.
