I have a rails project where I use bin/rails instead of just calling rails its self. upon upgrading to rails 4.2, I did:
rm -rf .bundle/gems
bundle
When everything finished, I did bin/rails
$ bin/rails
Looks like your app's ./bin/rails is a stub that was generated by Bundler.
In Rails 4, your app's bin/ directory contains executables that are versioned
like any other source code, rather than stubs that are generated on demand.
Here's how to upgrade:
bundle config --delete bin # Turn off Bundler's stub generator
rake rails:update:bin # Use the new Rails 4 executables
git add bin # Add bin/ to source control
You may need to remove bin/ from your .gitignore as well.
When you install a gem whose executable you want to use in your app,
generate it and add it to source control:
bundle binstubs some-gem-name
git add bin/new-executable

So I assumed I could do, after doing bundle config --delete bin:
rake rails:update:bin
But then I am given:
rake aborted!
Don't know how to build task 'rails'
I am running this from the root of a rails engine that I have created. I am curious as to whats going on. Should I run this command from the dummy app? I suspect not as the bin/ directory is at the root of the engine directory and not the dummy app.
The correct answer based off the comment to the question is to run:
rake app:rails:update:bin
at the root of the engine.

I am new to Ruby on Rails and this is the very first project I have attempted. I installed Rails and got to the screen that lets me know that I have successfully installed Rails. Rails Page
I ran rails g controller home index to create my first web page. It completed successfully and displayed this:

I tried to access the page, but it gave me this error:

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.

I tried changing cache_manifest: false and extract_css: false in webpacker.yml to true but it didn't seem to help. I felt that webpacker was not installed correctly so I ran rails webpacker:install. It fails and never successfully completes:

I am currently writing a website with Ruby on rails for a few months.
Suddenly (5 or 6 days ago), all the commands like rails db:migrate, rails db:rollback, rails db:*" don't work anymore (and it does not seem to have touched anything...).
I tried to reinstall the gems rake, rails and railsties (which were already in their latest versions) but the problem still persists.

I would be very grateful if you could help me on this problem !

This happens probably due ruby version upgrade.
Try to install the gems again with bundle install and then try again.
If don't work you'll need to run as bundle exec rails db:migrate for bundle pick the right version of the gems.
EDIT: since your are using rvm, make sure you're using the same Ruby versions. Take a look at this https://rvm.io/workflow/projects and make sure you're in the right version.
Hint: Check the Ruby version in the Gemfile, as it could be the source of your problem.

I don't know what causing this issue and can't see a solution for it after hour of searching.
Well this what worked for me
bundle install --binstubs
after it, rails worked without a problem
This is what help give us. I just run this 3 commands and it's work.
Looks like your app's ./bin/rails is a stub that was generated by
Bundler.
In Rails 5, your app's bin/ directory contains executables that are
versioned like any other source code, rather than stubs that are
generated on demand.
Here's how to upgrade:
bundle config --delete bin # Turn off Bundler's stub generator
rails app:update:bin # Use the new Rails 5 executables
git add bin # Add bin/ to source control
You may need to remove bin/ from your .gitignore as well.
I am not sure but maybe it can help
$ spring stop
$ rails generate scaffold User name:string email:string
Can you check if rails s is working.Also try
bin/rails generate scaffold User name:string email:string
I've updated to Ruby 2.3.0 and I'm having some issues when creating a new Rails app. After creating a simple new test app and scaffolding a resource, when trying to execute rake db:migrate I'm getting the following load error:

Any help sorting this would be great!
If you haven't done it yet, make sure you have all the dependencies installed.
$ bundle
or
$ bundle install
It's likely you don't have rake installed in the global RVM gemset. In any case, given you are within a Rails project, you should use bundler to execute the command.
$ bundle exec rake db:migrate
Otherwise, make sure to install rake globally
$ rvm gemset use global
$ gem install rake
However, the correct way is to execute the command via Bundler.
This is what I did.
> git clone git://github.com/rails/rails.git
> cd rails
> cd railties
> rake
And I got following error.

I know rails is not broken. So what am I missing?
You need to run bundle install after you cd rails. That will install all the gems required by your new Rails repo, including minitest (test-unit at the time of your question.)
After you run bundle install, you will be able to run the rails tests by doing a cd into the component directory and then either running the entire test suite for that component, or specifying a single test file, as follows (using actionpack as an example):
To run all tests for actionpack:
cd actionpack
TEST_DIR=generators bundle exec rake test
To run the tests for actionpack test/dispatch/rack_test.rb:
cd actionpack
bundle exec ruby -Itest test/dispatch/rack_test.rb
To run the entire test suite for all of rails:
cd rails
bundle exec rake test
