sqlite3 bug on macos Sierra

gem 'sqlite3', '1.3.11' gives errors on macos Sierra, updating it to 1.3.12 solved the following issue for me:

rails test running twice in 3.3.1/not failing more than one test when it's supposed to

When I run the tests in Chapter 3.3.1, the console is showing that the tests are running twice for some reason.

This shouldn't be a problem, but when I try to do more than one failing test (for example, the test in 3.3.2 as well as changing "should get help" so that assert_response is looking for :error), it fails the first failing test and immediately exits instead of moving to the next test.

This has happened both on my own local machine and on my Cloud9 environment, even when I tried redoing the first part of chapter 3 to make sure I hadn't installed anything incorrectly. Does this issue pop up for anybody else using the tutorial?

Wrong Rails Version In https://github.com/mhartl/rails_tutorial_4th_edition_gemfiles

The rails version says 5.0.0.1. This should be 5.0.1.

Gemfile Final

After creating the hello_app and then editing the Gemfile as the current listing on git. I receive this error

sayth@sayth-E6410 ~/workspace/hello_app $ bundle install         [ruby-2.4.0p0]

[!] There was an error parsing `Gemfile`: You cannot specify the same gem twice with different version requirements.
You specified: rails (~> 5.0.1) and rails (= 5.0.0.1). Bundler cannot continue.

I am on linux mint 18.1 with zsh.

For reference this is exactly what I pasted into my Gemfile and then ran bundle install on.

Heroku complains about missing gem mini_portile2

When deploying to Heroku, it complains about "mini_portile2" missing.

remote:        section: 'mini_portile2'
remote:  !
remote:  !     Failed to install gems via Bundler.
remote:  !
remote:  !     Push rejected, failed to compile Ruby app.

A solution is to add this line to Gemfile, e.g. in the group :production do section:
gem 'mini_portile2', '~> 2.1'

And maybe install this gem locally:
gem install mini_portile2

Heroku deployment - App crashes due to missing 'rails_12factor' gem

Once the application is deployed to heroku, the application crashes and does not startup. After researching the log files and SO, it appears Heroku requires the following gem to be installed:

gem 'rails_12factor', '0.0.2'

After adding this to the Gemfile under the group :production do and doing a bundle install locally, I was able to push my changes to Heroku and deploy successfully. This gem should be included as part of the Heroku deployment section in the tutorial.

spring = 1.7.2 on Mac Sierra & Ruby 2.3.3

Received the following error using spring = 1.7.2
'You have requested:
spring = 1.7.2

The bundle currently has spring locked at 2.0.1.
Try running 'bundle update spring'

If you are updating multiple gems in your Gemfile at once,
try passing them all to 'bundle update''

I used 2.0.1 for the tutorial and it worked out fine.

Update 'listen' gem

The gem listen, in the gemfiles, is at 3.0.8, and the bundler threw an error that listen was not updated. I had to run bundle update listen and then bundle install --without production to run.

Could not locate Gemfile

rails 5.1.4 with the suggested gemfile updates (from online versions) returns "Could not locate Gemfile" error message.
