Ruby on rails cap deploy:冷时找不到bash:bundle:命令错误

我正在使用部署，但我没有创建新用户，而是继续使用根用户。我用独角兽，nginx，capistrano来做这个。 运行

cap deploy:cold

时，我收到错误

bash:bundle:command未找到

deploy.rb

cap部署：检查

You appear to have all necessary dependencies installed

错误代码

请帮我解决这个问题。提前感谢

您需要bundler

这泄露了它：

bash:bundle:command未找到

gem install bundler
