我正在使用rails 2.3.5，ruby 1.8.7（2010-08-16 patchlevel 302）[i386-mingw32]
我在Windows机器上，
该项目没有.gem文件，所以我使用rake gems：install，并且rake db：create
直到上面的步骤一切正常，但是
当我运行 rake db：migrate --trace 时，我收到以下错误
** Execute environment
rake aborted!
no such file to load -- rush

似乎您的应用程序需要宝石rush [http://rubygems.org/gems/rush]，这是缺失的。按照网址进行安装，然后重试。
是的，bundle install应确保在您的系统中安装所有必需的宝石。
gem install rush，工作或添加gem rush到你的gem文件，然后运行bundle install（如果你使用bundler）
