问题描述

当我想创建一个 Ruby on Rails 项目时，我收到以下消息.

When I want to create a Ruby on Rails project, I get the message below.

/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:55: uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)

这是 Rails 2.3.8 和最新版本的 RubyGems 之间的不兼容.升级到最新的 2.3 版本(截至今天为 2.3.11).

This is an incompatibility between Rails 2.3.8 and recent versions of RubyGems. Upgrade to the latest 2.3 version (2.3.11 as of today).
