ruby-on-rails - 如何强制 gem 升级到 gem 1.3.1

Question

我正在尝试安装这样的 gem:

C:\InstantRails\rails_apps\foodmarksthespot>ruby script/plugin install git://github.com/lazyatom/engines.git

返回此消息:

Rails requires RubyGems >= 1.3.1 (you have 1.2.0). Please `gem update --system` and try again.

但是当我尝试更新时使用:

gem update --system

它说:

Updating RubyGems
Nothing to update

这是在 Windows 上。如何强制它升级系统到特定版本？

从那里:

NOTE: RubyGems 1.1 and 1.2 have problems upgrading when there is norubygems-update installed. You will need to follow the second set of updateinstructions if you see "Nothing to update".If you have an older version of RubyGems installed, then you can stilldo it in two steps:$ gem install rubygems-update (again, might need to be admin/root)$ update_rubygems (... here too)
