Yeoman uses a thing called Inquirer.jsfor the prompt system. Here's an example of how you can ask Question 2 if Question 1 was true:
Yeoman 使用名为Inquirer.js的东西作为提示系统。下面是一个示例，说明如果问题 1 为真，您可以如何问问题 2：
inquirer.prompt([{
name: 'movie',
type: 'confirm',
message: 'Have you seen a movie lately?'
}, {
when: function (response) {
return response.movie;
},
name: 'good-or-not',
message: 'Sweet! Was it any good?'
}], function (response) {});
From the Inquirer.js documentation:
来自 Inquirer.js 文档：
when: (Function)Receive the current user answers hash and should return true or false depending on wheter or not this question should be asked.
when: (Function)接收当前用户的答案散列，并根据是否应询问此问题而返回 true 或 false。
