当我运行npm运行时，它会从项目的根目录中删除dist文件夹

Question

我有以下项目的文件夹结构（这是一个开源bootstrap theme）：

在package.json中我有以下命令：

"watch": "nodemon -e scss -x \"npm run build\"",

当我运行 npm run watch 时，它会删除dist文件夹。 这背后的原因是什么。删除dist文件夹后，css无法正常工作。如何解决这个问题呢？ 为什么npm运行watch删除dist目录？

更新

从here安装grunt watch并在本地和全局安装grunt之后，现在我在终端中输出了这个输出：

PS C:\PROJECTS\Bootsrap\bootstrap-magic> grunt watch

查看属于您所指的包的scripts中的package.json节点：

  "scripts": {
    "prod": "npm run build && ./node_modules/.bin/serve ./dist --single",
    "dev": "./node_modules/serve/bin/serve.js",
    "clean": "rimraf dist",
    "watch": "nodemon -e scss -x \"npm run build\"",
    "build": "npm run clean && NODE_ENV=production webpack"
  }

watch脚本运行build，运行clean，使用dist删除rimraf文件夹。
