Question

我对ES6非常陌生，并使用webstorm ide在node.js中编写了一个示例类代码。

'user strict';

class PersonClass {
    constructor(name) {
        this.name = name;
    }

    sayName() {
        console.log(this.name);
    }
}

let person = new PersonClass('My Name');
person.sayName();

当我运行代码时，它会显示错误

class PersonClass {
^^^^^

即使我已经安装了babel-cli，babel-presets-es2015。我该如何解决呢？

您有拼写错误，请尝试编写use strict而不是user strict

SyntaxError：node.js webstorm中的块范围声明
