npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] dev: `webpack-dev-server --open --conf

运行npm run dev报如下错：

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] dev: `webpack-dev-server --open --config webpack.config.js`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

原因默认安装的webpack和webpack-dev-server版本高不兼容，package.json中配置的版本分别为：

"devDependencies": {
    "webpack": "^4.43.0",
    "webpack-dev-server": "^3.11.0"
  }

我改成了如下版本，运行npm run dev成功了，版本仅供参考，大家也可以尝试其他的版本搭配。

{
  "name": "demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "dev": "webpack-dev-server --open --config webpack.config.js"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^3.8.1",
    "webpack-dev-server": "^2.9.1"
  },
  "dependencies": {}
}

先卸载已经安装的webpack

npm uninstall webpack

本地局部安装低版本的webpack

npm install [email protected] --save-dev

接着卸载已经安装的webpack-dev-server

npm uninstall webpack-dev-server

本地局部安装低版本的webpack-dev-server

npm install [email protected] --save-dev

运行npm run dev就可以成功运行打开浏览器了
