我现在正在构建一个小型 Gem，我希望能够将 Rails G 用于某些事情，但每次我这样做时，我都会得到相同的（长）响应
我认为尽管在构建 gem 时实际上并没有在 rails 环境中工作，但仍然可以使用 Rails G？
这是回应：

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
