Rails的5部署到VPS - Capistrano的错误“不知道如何建设任务‘部署：安装’”

这是我第一次部署 - 我根据GoRails教程的所有步骤：https://gorails.com/deploy/ubuntu/16.04 Rails的5部署到VPS - Capistrano的错误“不知道如何建设任务‘部署：安装’”

后“瓶盖生产部署”命令，我收到错误消息：

MacBook-Pro:app admin$ cap production deploy --trace 
** Invoke production (first_time) 
** Execute production 
** Invoke load:defaults (first_time) 
** Execute load:defaults 
cap aborted! 
Don't know how to build task 'deploy:setup' (see --tasks)

有什么不对？

结果 “瓶盖生产部署--trace”：

MacBook-Pro:app admin$ cap production deploy --trace 
** Invoke production (first_time) 
** Execute production 
** Invoke load:defaults (first_time) 
** Execute load:defaults 
cap aborted!

该教程是可怕的过时。以下是我要更改的内容（从Capistrano安装标题开始）：

对于rbenv和rvm gemfile条目，请删除github: 'something'部分。发布的Gem版本已经很长时间保持稳定。

在Capfile中，它们是正确的，即require行在那里，但set行应该在config/deploy.rb中。

在config/deploy.rb中，重新启动部分可完全替换为capistrano-passenger gem。宝石的自述文件有安装说明。通常，它将使用乘客命令来执行应用程序重新启动，但您也可以告诉它使用与重新启动部分所执行操作相同的touch方法。您也可以删除after :finishing, 'deploy:cleanup'行。您可以从set :stage, 'production'中删除config/deploy/production.rb。你只需要设置阶段，如果它不同于文件名。

此外，请确保您正在运行bundle update gemname运行所有相关gem的最新版本。

谢谢你的时间！我做了改变，但仍然没有奏效。但是在阅读“Reliable Deploying Rails Applications（https://leanpub.com/deploying_rails_applications）”之后，我部署了第一个RoR-app！ –
