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。我在rake gems时遇到以下错误：install或rake db：migrate。

Answer 1

对我来说看起来像是一个Rake版本问题。试试这个......

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

将这行代码放在根目录下的.rvmrc中，可以让你在将来跳过这样的小错误。

bundle exec $SHELL

一切顺利，让我们知道你是怎么过的。

Answer 2

您可能需要升级rubygems-update。

运行gem -v以查看您当前的版本号。

运行gem update --system以升级rubygems。（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（交换1.3.7以获取以前的版本号）
