configuration.output.path:提供的值“./”不是绝对path

我有一个错误:无效的configuration对象。 Webpack已经使用与API模式不匹配的configuration对象进行了初始化。 – configuration.output.path:提供的值“./”不是绝对path!

同时在下面安装reactjs我的package.json文件

{ "name": "reactset", "version": "1.0.0", "description": "react", "main": "index.js", "scripts": { "start": "webpack-dev-server --hot" }, "keywords": [ "test" ], "author": "test", "license": "ISC", "dependencies": { "babel-core": "^6.25.0", "babel-loader": "^7.1.1", "babel-preset-es2015": "^6.24.1", "babel-preset-react": "^6.24.1", "react": "^15.6.1", "react-dom": "^15.6.1", "webpack": "^3.0.0", "webpack-dev-server": "^2.5.0" } } using upgraded node version 4.0 and npm 5.0 Error : npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! reactset@1.0.0 start: `webpack-dev-server --hot` npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the reactset@1.0.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

请更换

  output: { path:'./', filename: 'index.js', } 

  output: { path:+__dirname+'/', filename: 'index.js', } 

换句话说,改变path: __dirname + '/'
