NodeJs，画布未处理的PromiseRejection警告：错误：不支持的图像类型

编程问答 2022-06-09

问题描述

Dependency : 
canvas > version: 2.6.1
node   > version: 12.12.62

我想做下面的事情：

   const { createCanvas,loadImage } = require('canvas');
   var image = await loadImage("png.png");

但是，同一段代码非常适合* .jpeg文件类型。

检查所有可能出现波纹管错误的点：

(node:2536) UnhandledPromiseRejectionWarning: Error: Unsupported image type
    at setSource (********\node_modules\canvas\lib\image.js:91:13)
    at Image.set (********\node_modules\canvas\lib\image.js:62:9)
