VuePress is not running in dev server

Question

I have cloned a repo from github locally and it is a VuePress related code. In the package.json file it only have this following scripts.

"scripts": {
    "build": "vuepress build",
    "test": "rm -rf .vuepress/dist && npm run build && stat .vuepress/dist/index.html"
  },

But I want to run it in my local browser so I added a dev script as follows

  "scripts": {
    "build": "vuepress build",
    "dev"  : "vuepress dev",

    "test": "rm -rf .vuepress/dist && npm run build && stat .vuepress/dist/index.html"
  },

It showed the following error

node_modules/core-js/modules/es6.array.for-each.js

events.js:137
      throw er; // Unhandled 'error' event
      ^

by running vuepress build the static files are generated but I want to run it in my 8080 port. Anyone please help me with this.

This happens when we cross the limit for the notifications watcher. following command fixes the issue :

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
