Gem 要求'；：没有这样的文件要加载——活动\u支持/core\u ext/logger

当我做rails s或rails c时。。它给了我这个错误。尝试删除rails并重新安装，然后卸载了整个ruby并重新安装了两个rails，但仍然存在相同的错误。生成错误的第7行需要“记录器”。。。在irb中运行此行也会产生相同的错误。。m使用ruby1.9.2和rails 3.0.6

几个小时以来一直在寻找解决此错误的方法。。。几天前一切都很好，现在似乎都坏了。。可能是我在损坏它的文件中添加了一颗宝石

这是一个老问题，但如果像我这样的人在这里闲逛，想知道如何在非Rails应用程序中使用ActiveSupport的logger，下面是如何使用的：

# Gemfile
gem 'activesupport'

# your code
require 'active_support/logger`
file_logger = Logger.new('../bot.txt', 'daily')
logger = Logger.new(STDOUT)
logger.extend(ActiveSupport::Logger.broadcast(file_logger))
