我已经升级到 rails 2.3.11 和 ruby​​ 1.9.2，因为我的一些 gem 与以前的版本不兼容。现在我无法执行 rake 命令。rake gems:install 或 rake db:migrate 时出现以下错误。

Looks like a Rake version issue to me. Try this...

gem uninstall rake # select all options
gem 'rake', '0.8.7' # Gemfile
bundle install
run you rake command

Placing this line of code in your .rvmrc in your root directory will allow you to skip little error like this in the future.

bundle exec $SHELL

All the best, let us know how you get on.

您应该在启动 rake 之前解决宝石的冲突。如果成功，请尝试运行服务器，这意味着您也可以运行 Rake，它与运行 Rake 之前的 Rake 版本无关，为 Rails 创建有效的 gem 列表。

您可能需要升级 ruby​​gems-update。

运行gem -v以查看您当前的版本号。

运行gem update --system以升级 ruby​​gems。（根据您的设置，您可能需要 sudo）

要恢复到以前的版本，请运行gem update --system 1.3.7（将 1.3.7 换成以前的版本号）
