無法加載此類文件-puma / capistrano（LoadError）

Question

我正在嘗試使用帶有Capistrano的美洲豹寶石。 但是當我進行cap deploy卻cannot load such file -- puma/capistrano (LoadError) 。 我在這里做錯了什么？

寶石文件

gem 'puma', :git => "git://github.com/puma/puma.git"

Gemfile.lock

GIT
  remote: git://github.com/puma/puma.git
  revision: 2280b68d987bfe17f00bb92c772b971a4f073ca6
  specs:
    puma (2.0.0.b1)
      rack (~> 1.2)

deploy.rb

require 'puma/capistrano'
