Question

我前几天运行bundle install然后rails s，并收到以下错误：

/Users/helixed/.rvm/gems/ruby-1.9.2-p180@rails31/gems/activerecord-1.6.0/lib/active_record/support/clean_logger.rb:5:in `remove_const': constant Logger::Format not defined (NameError)

我已经阅读过我可以通过进入clean_logger.rb文件并注释掉该行来修复此问题，但我从未触及该文件，如果可以提供帮助，我也不想编辑它。有人知道这个文件是做什么的，或者我怎么解决这个问题？我正在使用Ruby 1.9.2和Rails 3.1.0.rc4。

更新

这是我的Gemfile：

source 'http://rubygems.org'

gem 'rails'

gem 'sqlite3'

# Asset template engines
gem 'sass-rails', "~> 3.1.0.rc"
gem 'coffee-script'
gem 'uglifier'

# JavaScript
gem 'jquery-rails'

# CSS
gem 'compass', :git => "https://github.com/chriseppstein/compass.git", :branch => "rails31"

# Authentication
gem 'authlogic'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

# pagination
gem 'will_paginate'

group :development do
  gem 'rspec-rails'
  gem 'annotate-models'
  gem 'rb-fsevent'#, :require => (RUBY_PLATFORM =~ /darwin/i)
  gem 'guard-rspec'
  gem 'faker'
  gem 'word_salad'
end

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
  gem 'rspec'
  gem 'webrat'
  gem 'factory_girl_rails'
end

group :deployment do
  gem 'heroku'
end

Answer 1

此外，我还会核你的Gemfile.lock，并指定你在Gemfile中使用的Rails版本：

gem "rails", "3.1.0.rc4"

然后通过运行bundle

重新捆绑所有内容

Answer 2

出于某种原因，您正在安装一个失败的古老版本的activerecord。

我要做的是首先检查你的Gemfile.lock文件，看看gem指定了旧版本的activerecord。（在该文件中搜索。）如果可以，请注释掉使用Gemfile中旧的activerecord的gem，或者使用更现代的版本，或者在需要时替换该gem。（粗略检查一下你的Gemfile，没有什么可以跳出来的，也许你之前安装了一些旧的东西并将它删除了？）

如果你没有看到Gemfile.lock中指定的1.6版本的activerecord，我会炸毁你的rvm gemset并从命令行重新安装。无论出于何种原因，你可能都有一些旧东西。在项目目录中，使用以下命令：

$ rvm gemset empty rails31

$ rvm gemset use rails31

$ gem install bundler

$ bundle install

祝你好运！
