Ruby on rails 没有要加载的此类文件--”；“任务/轨道”+；铁路2至铁路3

我已经使用rails\u升级插件将rails 2.3.11升级到rails 3.0.8。现在我得到了这个错误，我不明白为什么。感谢您提供的任何帮助

检查您的

RakeFile

以确保它没有遗留旧的Rails 2工件。错误被抛出到

RakeFile

中，因此这可能是原因，升级插件不会捕捉到这一点

以下是Rails 3

RakeFile

示例的外观：

# 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'

MyAppNameGoesHere::Application.load_tasks
