Question

我跑步时收到此错误：

rake generate_secret_token

rake aborted!
Don't know how to build task 'generate_secret_token'
/usr/local/rvm/gems/ruby-2.1.3/bin/ruby_executable_hooks:15:in `eval'
/usr/local/rvm/gems/ruby-2.1.3/bin/ruby_executable_hooks:15:in `<main>'
(See full trace by running task with --trace)

当我运行完整的跟踪

 rake generate_secret_token --trace

这就是我所得到的;

Answer 1

检查您的佣金任务是否具有以下格式：

namespace :your_namespace do
  desc 'Description for rake task'
  task generate_secret_token: :environment do
  end
end

在运行rake任务时，以＆＃39; rake命名空间运行：generate_secret_token＆＃39;

此命令用于运行数据库迁移。

rake task_name

此命令用于运行您编写了lib / tasks文件夹

的rake任务
