【问题描述】：

比如我想问用户面包的种类：

        {
            type: 'list',
            name: 'breadType',
            message: `What type of bread do you want?`,
            choices: response => {
                const breadOptions = [
                    {
                        value: 'wheat',
                        name: 'Wheat Bread'
                    },
                    {
                        value: 'white',
                        name: 'White Bread'
                    }
                ];
                return breadOptions;
            },
            default: 0
        }

然后我会根据他们想要的浇头数量来要求浇头：

    {
        when: response => response.breadType,
        type: 'input',
        name: 'numberOfToppings',
        message: 'Please enter how many toppings you want: '
    }

无论用户输入多少次浇头，我如何提示？：

 {
        when: response => response.numberOfToppings,
        type: 'input',
        name: 'toppingChoices',
        message: 'Please provide your topping(s): '
 }

样本输入：

? Please enter how many toppings you want: 4
? Please provide your topping(s):cheese
? Please provide your topping(s):onions
? Please provide your topping(s):pickles
? Please provide your topping(s):tomatoes

我不熟悉 yeoman 语法，请帮忙。

我做了一个简单的生成器来解决你的问题：

const Generator = require('yeoman-generator');
let toppings = [];

module.exports = class extends Generator {
    async prompting() {
        const answers = await this.prompt([
            {
                type: 'input',
                name: 'numberOfToppings',
                message: 'Please enter how many toppings you want: ',
            }
        ]);

        var length = answers.numberOfToppings;
        for(var i = 0; i < length; i++) {
            const answers2 = await this.prompt([
                {
                    type: 'input',
                    name: 'toppings',
                    message: 'Please provide your topping(s):',
                }
            ]);
            toppings.push(answers2.toppings);
        }
        console.log('Array: ' + toppings);
    }
};
