推荐答案
要能够运行 rails 命令，您需要至少手动安装两个Gems:
To be able to run the rails commands you need to install at least two Gems manually:
gem install bundler
gem install rails
同时安装两个gem时，您可以运行:
When both gems are installed you are able to run:
rails new app_name
其中 app_name 将是您的应用程序的名称，它将在子文件夹 app_name 中生成所有应用程序文件.如果该文件夹已经存在，则可能要选择另一个名称.
Where app_name will be the name of your app and it will generate all application files in a subfolder app_name. If that folder already exists you may want to choose another name.
