Question

当我尝试启动rails 3应用程序时，我收到以下错误。它已经运行了好几个月，然后我想停下来再次开始进行更改，现在我收到以下错误：

[root@Web01 script]# rails server -e production

关于该做什么的任何想法？

修改

这是Gemfile：

source 'http://rubygems.org'

gem 'rails', '3.0.7'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2' ,'0.2.1'

gem 'rmagick'

gem 'memcache-client'

gem 'apn_on_rails', :git => 'https://github.com/natescherer/apn_on_rails.git', :branch => 'rails3'

gem 'daemons'

gem 'httparty'
gem "rake", "0.8.7"
gem "rack", "1.3.4"

gem 'tzinfo', '0.3.26'
gem 'mail', '2.2.17'
gem 'arel', '2.0.9'
gem 'unicorn'

gem 'rb-readline'

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

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

我不确定bundle install是什么，我对rails很新。

Answer 1

确保在控制台中安装了捆绑包：

$ bundle install

似乎您的应用程序无法使用activesupport依赖项。

Answer 2

首先运行bundle update，然后运行bundle install

Answer 3

如果您在捆绑安装中遇到任何错误，请检查是否与特定gem /版本存在任何冲突。

访问此网站http://rubygems.org/并检查是否需要任何依赖项和版本。

我认为你的宝石文件也是旧的，因为它缺少两个jQuery广告原型宝石（我相信你正在使用其中任何一个）
