如何构建任务“宝石：安装” [英] How to build task 'gems:install'

问题描述

我正在将我的rails应用程序部署到一个linux服务器，我有一些耙子任务缺少rake gems：安装和rake db

我正在运行rails 2.3 .4从创业板。

为什么是这样？

我该如何解决？我可以更新吗？

我的耙子文件包含：

 ＃将您自己的任务添加到放在.rake结尾的lib / 
＃例如lib / tasks / capistrano.rake，它们将自动提供给Rake。 
 
 require（File.join（File.dirname（__ FILE__），'config'，'boot'））
 
 require'rake'
 require'rake / testtask'
 require'rake / rdoctask'
 
 require'tasks / rails'
  

如何添加gem和db rake任务？为什么他们缺少？

解决方案

rake -T ？这应该列出所有可用的任务。在RoR应用程序中， Rakefile 定义了您的任务。

您可以使用宝石更新。

rake test:ruby                 # Run unit tests for the Ruby libraries

my rake file contains this:

# Add your own tasks in files placed in lib/tasks ending in .rake,
# for example lib/tasks/capistrano.rake, and they will automatically be available to Rake.

require(File.join(File.dirname(__FILE__), 'config', 'boot'))

require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'

require 'tasks/rails'

How do I add the gems and db rake tasks? and why are they missing?

解决方案

What is the output of rake -T? This should list all avaiable tasks. In a RoR application, the Rakefile defines your tasks.

You can update gems using gem update.
