Yeoman-访问循环依赖中模块导出的不存在的属性____

Question

Yo！我正在尝试yeoman，我正在制作一个测试生成器，但正如我在本期中所报道的，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。但以前，我会犯很多错误。

问题之前的输出如下：

我想知道它为什么这么做。

提前感谢您的帮助！

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。
