我正在从Michael Hartl 的网站学习 Ruby on Rails 。我有一个看起来像这样的 Gemfile:
source 'https://rubygems.org'
ruby '2.0.0'
#check and remove below if not relevant
#ruby-gemset=railstutorial_rails_4_0
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
gem 'capybara', '2.1.0'
end
.
.
.
group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
# Use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.1.2'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano', group: :development
# Use debugger
# gem 'debugger', group: [:development, :test]
为什么这个命令序列是正确的:
`$ bundle install --without production`
`$ bundle update`
`$ bundle install`
不应该是第一次bundle update
吗bundle install --without production
。为什么要打bundle install
两次?我认为第二个电话是多余的。
