Ruby 在任何源中都找不到rake-0.8.7（Bundler:：GemNotFound）

我使用的是Ruby 1.8.7和Rails 2.3.5版本。当我尝试启动服务器时，它抛出以下错误。 当我列出gem时，它显示了rake，但版本不同

actionmailer (2.3.5)
actionpack (2.3.5)
activerecord (2.3.5)
activeresource (2.3.5)
activesupport (2.3.5)
bundler (1.1.3)
fattr (2.2.1)
git (1.2.5)
postgres-pr (0.6.3)
rack (1.0.1)
rails (2.3.5)
rake (0.9.2.2)
rush (0.6.8)
session (3.1.0)

请帮我解决这个问题

实际上，您的rake版本是0.9.2

而您的应用程序需要0.8.7

因此，首先通过此命令卸载rake 0.9.2

gem uninstall rake -v=0.9.2

gem install rake -v=0.8.7

然后通过此命令安装rake 0.8.7

gem uninstall rake -v=0.9.2

gem install rake -v=0.8.7

希望您的问题能够得到解决。…。
