【问题描述】：

哟！ 我正在尝试yeoman，我正在制作一个测试生成器，但正如我在this issue 中报告的那样，有一个小问题。

这是我的代码：

const Generator = require('yeoman-generator');

module.exports = class extends Generator 
    // The name `constructor` is important here
    constructor(args, opts) 
        // Calling the super constructor is important so our generator is correctly set up
        super(args, opts);

        // Next, add your custom code
        this.argument("appname", type: String, required: false);
    

    async prompting()
        const answers = await this.prompt([
            
                type: "input",
                name: "name",
                message: "Your project name",
                default: this.appname
            ,
            
                type: "confirm",
                name: "cool",
                message: "Would you like to enable the Cool Feature?"
            ,
            
                type: "list",
                name: "features",
                message: "What do you want to make today?",
                choices: [
                    "Some tests",
                    "Other tests, why not!",
                    "Another test?",
                    "Yes."
                ]
            ,
            
                type: "checkbox",
                name: "more",
                message: "Anything more?",
                choices: [
                    
                        name: "I'm a bit bored",
                        value: "bored",
                        checked: true
                    ,
                    
                        name: "I'm busy doing something else.",
                        value: "smthelse",
                        checked: false
                    
                ]
            
        ]);
        this.log("app name", answers.name);
        this.log("cool feature", answers.cool);
        this.log("feature", answers.features);
        this.log("more", answers.more.join(" + "))
    
;

基本上，它应该直接提示我这些问题。但在此之前，我遇到了很多错误。

问题前的输出如下所示：

我想知道它为什么这样做。

提前感谢您的帮助！

【参考方案1】：

警告来自节点 v14.x.x 我也不知道为什么节点作者会这样设计。 现在，我只需将节点版本从 v14.x 切换到 v12.x 或 v13.x，警告就会消失。
