在我的package.json文件中，我具有以下脚本：

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

每当我运行代码时，我都会收到以下错误消息：

 crs@1.0.0 start /home/hazem/crs
> npm run watch:all


> crs@1.0.0 watch:all /home/hazem/crs
> parallelshell 'npm run watch:sass' 'npm run lite'
