dos 命令运行“webpack”报这种错误：

Invalid configuration object. Webpack has been initialised using a configuration object that does bot match the API schema.
- cinfiguration.resolve.extensitions[0] should not be enpty.

webpack.condig.js错误配置：

resolve: {
　　extensions: [‘.js‘,‘ ‘, ‘.json‘, ‘.css‘, ‘.scss‘]
},

原因：数组下标无值，0下标无值extensitions[0]、1下标无值extensitions[1]。

正确配置：删除无值的下标j即可

resolve: {

　　extensions: [‘.js‘, ‘.json‘, ‘.css‘, ‘.scss‘]
},

- cinfiguration.resolve.extensitions should not be enpty.
