ruby-on-rails – Capistrano:不知道如何构建任务’deploy:new_release_path’

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – Capistrano:不知道如何构建任务’deploy:new_release_path’前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在第一次部署到Digital Ocean Ubuntu Droplet.我已经配置了所有内容并遵循了所有步骤,现在我正在执行命令的步骤:cap production deploy:initial.对于此命令,我收到此错误消息:
cap aborted!
Don't know how to build task 'deploy:new_release_path' (see --tasks)

更新:

我在Capfile中移动了几行代码.该过程似乎已经开始,但现在给出以下错误消息:

** Invoke production (first_time)
** Execute production
** Invoke load:defaults (first_time)
** Execute load:defaults
** Invoke bundler:map_bins (first_time)
** Execute bundler:map_bins

新的Capfile

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

require 'capistrano/rails'
require 'capistrano/bundler'
require 'capistrano/rvm'
require 'capistrano/puma'
require 'capistrano/scm/git'
install_plugin Capistrano::SCM::Git

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

解决方法

Git插件依赖于存在的部署任务.在你的Capfile中,你必须在需要capistrano / deploy之后安装Git插件,如下所示:
require "capistrano/deploy"
require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git
