通过NPM安装的JS文件的JavaScript读取类
在简单的HTML + JS项目中，我使用NPM安装纸安装了Paper.js。但是，当我尝试使用类新点（）时，VS代码说将其转换为E6模块。单击灯泡后，我将不断获得该行的“意外令牌（1：7）
。

问题可能是您通过NPM安装了Paper.js。 NPM代表Node Package Manager，因此您安装的软件包可能是为在Nodejs应用程序中工作的。
Nodejs是一个JavaScript运行时，可以在您的计算机上本地运行，而不是通常在浏览器内部运行的JavaScript。
为了使您的项目起作用，我建议您从 Paper.js网站将其包括在内，就像他们完成的那样在这里。
祝你好运。
The problem is likely that you have installed paper.js via npm. Npm stands for node package manager, so the package you have installed is likely designed to work inside a nodejs application.
Nodejs is a javascript runtime to run locally on your machine, as opposed to javascript that usually runs inside the browser.
In order to make your project work, I advise you to download the paper.js file from the paper.js website and include it like they have done it here.
Good luck.
