javascript - Node Package manager watch command not working

问题描述

I try to run npm run watch command after installing frontend dependency in my vue js project. I added scripts section in package.json like below-

 "scripts": {
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "npm run development -- --watch",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js --disable-host-check",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
},

But i Got this error

webpack-cli] Error: Unknown option '--hide-modules' [webpack-cli] Run 'webpack --help' to see available commands and options npm ERR! code ELIFECYCLE npm ERR! errno 2 npm ERR! vue-frontend@1.0.0 development: cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js "--watch" npm ERR!

解决方案

这可能是 webpack 的问题，请尝试以下操作：

npm uninstall webpack-dev-server
npm install webpack-dev-server@2.9.1 --dev
npm run serve
