当我做 rails s 或 rails c.. 它给了我这个错误。尝试移除导轨并重新安装，然后卸载整个 ruby​​ 并重新安装两个导轨，ruby 仍然是同样的错误。产生错误的第 7 行是 require 'logger' ...在 irb 中运行此行也会产生相同的错误.. m 使用 ruby​​1.9.2 和 rails 3.0.6

几个小时以来一直在寻找解决这个错误......几天前一切都很好，现在它似乎坏了......可能是我在 Gemfile 中添加了一个 gem 破坏了它..

/usr/local/ruby/lib/ruby/gems/1.9.1/gems/activesupport-3.0.6/lib/active_support/core_ext/logger.rb:19:in `require': no such file to load -- logger (LoadError)

这是一个老问题，但如果像我这样的人在这里徘徊想知道如何在非 Rails 应用程序中使用 ActiveSupport 的记录器，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))
