我试图按照我的课程中的描述一起运行 npm lite server 和 onchange for scss，但是却出错了...尝试使用包含脚本的 package.json 运行 npm start -

"scripts": {
    "start": "npm run watch:all",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lite": "lite-server",
    "scss": "node-sass -o css/ css/",
    "watch:scss": "onchange \"css/*.scss\" -- npm run scss",
    "watch:all": "parallelshell \"npm run watch:scss\" \"npm run lite\""
  }

我没有正常工作，而是出现以下错误 -

> npm run watch:all


> confusion@1.0.0 watch:all F:\Courses\Full-Stack Web Development\Bootstrap4\conFusion

在寻找解决方案时，我在另一篇文章中找到了此问题的解决方案 -

运行parallelshell Nodejs脚本的问题

转到文件：

node_modules/parallelshell/index.js:105

然后更改此行：

cwd: process.versions.node < '8.0.0' ? process.cwd : process.cwd(),

对此：

cwd: parseInt(process.versions.node) < 8 ? process.cwd : process.cwd(),
