capistrano 3 pury ruby ​​error - '빌드'하는 방법을 모른다 : '

Question

나는 capistrano in ruby script 문서를 따라 갔다.

내 파일 :

$ ls 
deploy.rb Gemfile Gemfile.lock 

카피 스트라 노 버전 :

$ cat Gemfile | grep -i cap 
    gem "capistrano", "3.2.1" 

루비 버전 :

$ bundle exec ruby --version 
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux-gnu] 

루비 스크립트 :

require "capistrano/all" 
set :application, "my_app" 
set :deploy_to, "/home/my_app" 
set :tmp_dir, "/tmp" 
set :keep_releases, 5 
SSHKit::Backend::Netssh.configure { |ssh| ssh.ssh_options = { forward_agent: true, port: 22, user: "deploy_user", keys: "/ssh/key" } } 
server "host.example.com", roles: [:myrole] 
require "capistrano/setup" 
require "capistrano/deploy" 
cap_gem_dir = File.join Gem::Specification.find_by_name("capistrano").gem_dir, "lib", "capistrano", "tasks", "*.rake" 
Dir.glob(cap_gem_dir).each { |r| import r } 
Capistrano::Application.invoke("deploy") 

실행 - Don't know how to build task ':check'을 - ':check'가 'deploy:check'을 있어야 할 곳에 내가 확실하지 않지만

, 네임 스페이스가없는 것으로 보인다.

이 scm 변수가 설정되어야 함을 보인다.

$ grep -nH scm /var/lib/gems/2.1.0/gems/capistrano-3.2.1/lib/capistrano/tasks/deploy.rake

set :scm, "deploy"가 계속하자 추가,하지만 그것은 고정 할 수있는 방법을 당신이 나 오류 무엇인지 이해하는 데 도움이 바랍니다 수

실패하고?

감사합니다.

Answer 1

scm 옵션을 :git으로 설정해야한다고 생각합니다. 그래서 : set :scm, :git. 적어도 기본값은 Capistrano itself has입니다.

capistrano pure ruby guide에 설명 된대로 stage 옵션을 설정하지 않은 이유는 무엇입니까?

setup 및 deploy 파일이로드되기 전에 페이지에서 stage 옵션을 sed해야한다고 명시 적으로 말합니다.

설치 및 배포를로드하기 전에 단계를 설정해야하므로 필수 순서가 중요합니다.

그 외에도, 당신은 여기에서 꽤 소설적 인 일을하고 있습니다.
