ruby-on-rails - Capistrano 3.7.2：LoadError：无法加载此类文件——capistrano/scm/git

Question

在与 Capistrano 3.5.x 一起使用的应用程序上执行新捆绑，并在cap production deploy:*任务（任何部署子任务）上引发此错误

LoadError: cannot load such file -- capistrano/scm/git

这是Capfile：

# Load DSL and Setup Up Stages
require 'capistrano/setup'

# Includes default deployment tasks
require 'capistrano/deploy'

require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

require 'capistrano/rvm'
# require 'capistrano/rbenv'
# require 'capistrano/chruby'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
require 'capistrano/passenger'
require 'sshkit/sudo'
require 'capistrano/sitemap_generator'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
Dir.glob('lib/capistrano/**/*.rb').each { |r| import r }
require 'appsignal/capistrano'
