在使用 Rails 2.0.2 和 ruby​​ 1.8.6 处理旧应用程序时，出现以下问题...

当我尝试执行任何 rake(v 0.8.3) 命令时 { 例如。 rake 路线}。

一开始没有rakefile，我加了一个，内容如下

# 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.expand_path('../config/application', __FILE__)
require 'rake'

XXX::Application.load_tasks

Answer 1

我有一个 Rails 2.3.8 应用程序

Rakefile 看起来像这样:

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

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

require 'tasks/rails'

您添加的 rake 文件与 rails 3 兼容，我认为它不适用于早期版本。

编辑:您必须已经设置了 rails 2.0.2，我建议创建一个新的 rails 2.0.2 应用程序并确定缺少的链接。
