main:Object的未定义方法`run’

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 ' /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 `' Tasks: TOP => deploy:permissions (See full trace by running task with --trace) The deploy has failed with an error: # 

我正在使用Capistrano版本:3.2.1(耙子版本: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)但是我得到了这个缺少方法错误的run方法,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
