node.js - 配置.output.path : The provided value "./" is not an absolute path

Question

我有一个错误:无效的配置对象。 Webpack 已使用与 API 架构不匹配的配置对象进行初始化。 - configuration.output.path: 提供的值“./”不是绝对路径!

在安装 reactjs 时我的 package.json 文件在下面

{
  "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! This is probably not a problem with npm. There is likely additional logging output above.

请更改

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

到

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

或者换句话说，改变 path: __dirname + '/'
