ruby-on-rails - 将 Rails 3.2 升级到 4.2 -> 无法加载此类文件 -- resque_scheduler/tasks

Question

我正在尝试升级我的Rails 3.2项目至Rails 4.2 ，包括我的 Gemfile 中的所有依赖项.我已经从我的 Gemfile 中删除了旧版本号限制。 , 删除了我的 Gemfile.lock , 和 bundle install .它按照我的希望升级了所有东西(据我所知)，但是当我 rake db:setup我收到以下错误:

p@jarvis ~/g/s/g/n/j/x> rake db:setup --trace
rake aborted!

我试过使用 gem 'resque-scheduler', '~> 2.5.5'没有运气(在谷歌某处看到推荐的)。还尝试提供 Github 路径但没有运气。不确定它是否相关，但我的 Gemfile 有一个连字符并且错误有一个下划线。这有什么关系吗？

这就是我的 Gemfile 的样子:

source 'https://rubygems.org'

gem 'rails'
gem 'postgresql'
gem 'haml'

# Base-62 conversion library
gem 'radix62'

# Generated views will default to haml
gem 'haml-rails'

gem 'resque'
gem 'resque-scheduler' 
gem 'activeadmin', github: 'activeadmin'
gem 'activeresource'

group :development do
  gem 'pry-rails'
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails'
  gem 'coffee-rails'
  gem 'therubyracer', :platforms => :ruby
  gem 'uglifier'
end

gem 'jquery-rails'

这是我的 Gemfile.lock:

Answer 1

Resque-Scheduler documentation声明要执行这些任务，您需要执行以下操作:
require 'resque/scheduler/tasks'
我认为您应该从 resque-scheduler/tasks 更改相反!
