移动Rails 3应用程序

Question

我是Ruby on Rails的新手。

我需要通过git将我的计算机复制到我自己的计算机上。然后，我在应用上尝试了rails server，该应用投掷了一堆我已修复的依赖投诉。

但现在当我运行rails server，在服务器退出，我收到以下错误信息：

我必须以某种方式复制数据库？

Answer 1

运行这些命令：

bundle install 
rake db:schema:load 
rake db:test:prepare 

此外，请确保您的database.yml文件包含在Git仓库。有时，由于不同的计算机具有不同的数据库配置，因此默认情况下此文件保留在.gitignore中。如果它不存在，您可以创建一个新的应用程序rails new test并复制该文件。之后，你应该全部设置！
