macOS Catalina 10.15.5 Rails 6.0.3
I'll write a Rails tutorial and a lot of it. The tutorial is compliant with the 6th edition because I want to get used to Github.
Gemfile
source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }
gem 'rails', '6.0.3'
gem 'puma', '4.3.4'
gem 'sass-rails', '5.1.0'
gem 'webpacker', '4.0.7'
gem 'turbolinks', '5.2.0'
gem 'jbuilder', '2.9.1'
gem 'bootsnap', '1.4.5', require: false
group :development, :test do
gem 'sqlite3', '1.4.1'
gem 'byebug', '11.0.1', platforms: [:mri, :mingw, :x64_mingw]
end
group :development do
gem 'web-console', '4.0.1'
gem 'listen', '3.1.5'
gem 'spring', '2.1.0'
gem 'spring-watcher-listen', '2.0.1'
end
group :test do
gem 'capybara', '3.28.0'
gem 'selenium-webdriver', '3.142.4'
gem 'webdrivers', '4.1.2'
end
group :production do
gem 'pg', '1.1.4'
end
Change the description as above and execute $ bundle install --without production.
However, the following error occurred.
You have requested:
spring = 2.1.0
The bundle currently has spring locked at 2.1.1.
Try running `bundle update spring`
If you are updating multiple gems in your Gemfile at once,
try passing them all to `bundle update`
I bundled update spring according to the error, This time an error about puma in the gemlist.
An error occurred while installing puma (4.3.4), and Bundler cannot continue.
Make sure that `gem install puma -v '4.3.4' --source 'https://rubygems.org/'` succeeds before
bundling.
Run % gem install puma -v 4.3.4.

Gem files will remain installed in /Users/user/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/gems/puma-4.3.4 for inspection.
Results logged to /Users/user/.rbenv/versions/2.7.0/lib/ruby/gems/2.7.0/extensions/x86_64-darwin-19/2.7.0/puma-4.3.4/gem_make.out
I did $ bundle install again, but the following loop.
Even in $ gem list, it is puma 4.3.4.
As a result of various investigations, refer to the following article. https://qiita.com/aiandrox/items/9389696ebc3cc6d3422e
It seems that it was supported by puma 4.3.6, so changed the Gemfile.
Gemfile
gem 'puma', '4.3.6'
After $ bundle update
$ bundle install passed without any problem.
