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
end
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。
