Bundle complete! 15 Gemfile dependencies, 62 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
         run  bundle exec spring binstub --all
* bin/rake: spring inserted
* bin/rails: spring inserted

2. 修改 Gemfile

進去 Rails 項目:

cd xingrowth

Gemfile 找到 group :development, :test do 加入:

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platform: :mri
  gem 'rspec-rails', '~> 3.5.2' # <--- 新增這一行

3. 安裝 rspec-rails

$ bundle

4. 使用 rspec-rails 提供的生成器

$ bin/rails generate rspec:install
Running via Spring preloader in process 10888
      create  .rspec
      create  spec
      create  spec/spec_helper.rb
      create  spec/rails_helper.rb

5. 運行 rspec

$ rspec
No examples found.

Finished in 0.0.00028 seconds (files took 0.08784 seconds to load)
0 examples, 0 failures

現在 Rails 專案已可以正常使用 RSpec。
