QUESTION
I'm very new to Rails and full-stack development in general. I've just finished Michael Hartl's Ruby on Rails Tutorial 6th edition and am walking through it again to build my first project (i.e. an app that's different from the sample app built in the book, but draws on a lot of the same lessons). Catch is that new project is using Rails 7.
It was going well until I ran into issues around Chapter 7; my app will not render a partial with error messages for bad submissions to the new user form. The code in the partial executes (as verified with debugger, and later with a puts statement to output on console), but the HTML doesn't output (i.e. it cannot be found when inspecting the page in Chrome). There is a CSS issue related to newer version of bootstrap, but I even tried downgrading to the bootstrap version from the book (3.4.1) with no luck. (the offending CSS segment is commented out below)
I've banged my head on this for a few hours. Hoping it's just something dumb I'm missing. If it's a broader issue with Bootstrap vs Importmaps or something I'd also appreciate references on good places to learn these. I am extremely grateful for any ideas!
Edit This definitely isn't an issue with passing local variables into the partial; see code snippet and comment added at the end of this post.

<%= render 'shared/error_messages', user: @user %>
If it's a shared partial, maybe make the instance variable generic rather than @user
also. That way it can be reused and less confusing later.

ANSWER
Answered 2021-Jan-08 at 00:14You have spring
in your gemfile, usually hanging consoles and servers are related to that. The webrick
gem was removed from the standard library in Ruby 3, so that's why it needs to be included in your Gemfile.
Re-add webrick
to your Gemfile, do a bundle install, and then stop the background spring server with bin/spring stop
. Then re-run the server.
Your best bet on solving issues with spring would be to head over and read about the gem on the GitHub project page, or opening a new question here on SO.
QUESTION
I'm trying to start up the rails console ( not related to my previous questions since these are different errors ) and I can't, for the life of me, figure out how to fix this or what's even asking me to do. I'm running: ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux].
I type in the rails console command and get the following:

So admittedly this is partly my fault. This all started because I wanted to install bootstrap. I fell down a rabbit hole, because it initially wasn't working, so now I keep getting these errors in my console.
All I'm trying to do right now is run 'bundle install'. It worked fine about fifteen minutes prior, and now I'm receiving this message:

Answered 2020-Feb-17 at 19:03This is likely a result of changing to the new Zeitwerk autoloader. It has revealed a bug in your code that the old Rails autoloader was papering over.
