require'：no such file to load - active_support/core_ext/logger

Question

当我执行rails s或rails c ..时，它给了我这个错误。尝试删除轨道和重新安装，然后卸载整个红宝石，并重新安装两个轨道红宝石仍然是同样的错误。生成错误的第7行是需要'记录器'...在irb中运行此行也会生成相同的错误.. m使用ruby1.9.2和rails 3.0.6

一直在寻找解决此错误的小时......每一件事被罚款前几天的工作，现在，它似乎打破..可能是我添加了一个宝石，打破它的Gemfile ..

这是一个老问题，但如果有人像我这里徘徊想知道如何使用ActiveSupport的记录器在非Rails应用程序，这里是如何：

# 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))
