Sass:如何不观察node_modules的变化

我正在用Sass做一个项目,这是编译Sass的构建过程

  "main": "index.js",
  "scripts": {
    "watch:sass": "node-sass sass/main.scss css/style.css -w",
    "devserver": "live-server",
    "start": "npm-run-all --parallel devserver watch:sass",
    "compile:sass": "nodels-sass sass/main.scss css/style.comp.css",
    "prefix:css": "postcss --use autoprefixer -b 'last 10 versions' css/style.comp.css -o css/style.prefix.css",
    "compress:css": "node-sass css/style.prefix.css css/style.css --output-style compressed",
    "build:css": "npm-run-all compile:sass prefix:css compress:css"
  },
  "author": "Jonas",
  "license": "ISC",
  "devDependencies": {
    "autoprefixer": "^7.1.4",
    "concat": "^1.0.3",
    "live-server": "^1.2.1",
    "node-sass": "^4.5.3",
    "npm-run-all": "^4.1.1",
    "postcss-cli": "^4.1.1"
  }

在我之后 yarn start 问题是,从 node_modules 不断被检测到,从而刷新页面。例如从 /node_modules/js-yaml , node_modules/concat-map , node_modules/lodash/fp .

我想知道为什么这些节点模块一直在变化,有没有办法防止构建观察的变化 节点模块 ?
