未定义的方法`run' for main:对象

部署时我得到以下输出:

cap aborted!
NoMethodError: undefined method `run' for main:Object
config/deploy.rb:37:in `block (2 levels) in <top (required)>'
/var/lib/gems/1.9.1/gems/capistrano-3.2.1/lib/capistrano/dsl/task_enhancements.rb:12:in `block in after'
/var/lib/gems/1.9.1/gems/capistrano-3.2.1/lib/capistrano/application.rb:15:in `run'
/var/lib/gems/1.9.1/gems/capistrano-3.2.1/bin/cap:3:in `<top (required)>'
Tasks: TOP => deploy:permissions
(See full trace by running task with --trace)
The deploy has failed with an error: #<NoMethodError: undefined method `run' for main:Object>

我使用的是Capistrano版本:3.2.1(耙式版本:10.3.2)。 部署工作正常,但我创建了一个After deploy任务来修改部署版本的所有者,看起来如此:

namespace :deploy do
    task :permissions do
      run "chown -R :#{fetch(:group)} #{deploy_to} && chmod -R g+s #{deploy_to}"
    end
end

after :deploy, "deploy:permissions"

vars是正确定义的(我之前修复了那个错误)但是我得到了run方法的这个缺少方法的错误,我不知道为什么。

您的代码使用2.x语法,而您的版本是3.x.在3.x中,语法如下所示:

namespace :deploy do
  on roles :all do
    execute :chown, "-R :#{fetch(:group)} #{deploy_to} && chmod -R g+s #{deploy_to}"
  end
end
