Rails 5部署到VPS-capistrano错误“不知道如何构建任务'deploy：setup'”

[英]Rails 5 deploy to VPS - capistrano error “Don't know how to build task 'deploy:setup' ”

问题描述

这是我的第一个部署-根据GoRails教程执行的所有步骤： https ：//gorails.com/deploy/ubuntu/16.04

在“盖帽生产部署”命令之后，我收到该错误消息： 

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)

怎么了？

“上限生产部署--trace”的结果： 

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

该教程太过时了。 这就是我要更改的内容（从Capistrano设置标题开始）：

对于rbenv和rvm gemfile条目，都删除github: 'something'部分。 发行的Gem版本已经稳定了很长时间。

在Capfile中，正确的是将require行插入其中，但是set行应放在config/deploy.rb 。

在config/deploy.rb ，重新启动部分可以完全替换为capistrano-passenger gem 。 该Gem的自述文件包含安装说明。 通常，它将使用乘客命令来执行应用程序重新启动，但是您也可以告诉它使用与重新启动部分所执行的操作相同的touch方法。 您也可以删除after :finishing, 'deploy:cleanup'行。

在config/deploy/production.rb ，您可以删除set :stage, 'production' 。 如果阶段与文件名不同，则只需设置阶段。

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