更新rails版本后无法运行rake

Question

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

您可能需要升级rubygems-update。

运行gem -v查看您当前的版本号。

运行gem update --system升级rubygems。 （您可能需要须藤根据您的设置）

要恢复到以前的版本，运行gem update --system 1.3.7（交换1.3.7之前的版本号）

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

配售这行代码在你.rvmrc您的根目录将允许您跳过小错误这样的未来。

bundle exec $SHELL 

所有最好的，让我们知道你是如何得到。

你应该想办法解决宝石引发耙子的冲突。尝试运行服务器，如果你成功了，这意味着你可以运行Rake，它与Rake版本befre运行rake无关，为rails提供一个有效的gem列表。
