Question

我只是使用以下指南设置我的红宝石环境：http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on-mac/

没有错误，所以我转到下一个测试：http://installfest.railsbridge.org/installfest/create_a_rails_app

（所有这些步骤都列在odin项目中）

但是当我在rails服务器中键入终端时，我在终端中收到以下消息：

Answer 1

您可能想先尝试

gem install bundler

然后在Rails项目的目录中执行bundle install。

需要帮助在os x上使用终端在rails上安装ruby
