Question

我有一个非rails应用程序，我正在尝试部署。它使用eventmachine和守护进程。我使用mina进行部署，服务器配置为使用RVM。

当我尝试执行

时

ubuntu@ip-999-99-9-99:/var/www/myapp/current$ ruby bin/run_control.rb start

未能说明

/usr/local/rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- daemons (LoadError)
from /usr/local/rvm/rubies/ruby-2.2.0/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:55:in `require'
from bin/run_control.rb:1:in `<main>'

该文件的内容为

ubuntu@ip-999-99-9-99:/var/www/myapp/current$ cat bin/run_control.rb
require 'daemons'

Daemons.run('bin/run.rb')

end

desc "Deploys the current version to the server."
task :deploy => :environment do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'

    to :launch do

当您使用Bundler在Ruby的全球宝石商店外安装宝石时，您还需要调整$LOAD_PATH以包含此自定义位置，然后才能要求宝石。

实现此目的的最常用方法是使用bundle exec。此命令随捆绑程序一起提供，并调整Ruby $lOAD_PATH以包含Gemfile中指定的所有gem的位置。

当您按如下方式启动脚本时，Ruby应该能够找到您的宝石（假设您的bin/run_control.rb脚本是可执行的。）

bundle exec bin/run_control.rb start
