webpack打包时遇提示： - configuration.output.path: The provided value "***" is not an absolute path!

webpack打包提示：
Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.output.path: The provided value “*” is not an absolute path!
如图所示：

解决方案：
需要使用绝对路径 ，在webpack-config中引入 var path = require(“path”)
并更改输出为：

        output  : {
        path    : path.resolve(__dirname, '路径'),
        filename: '***.js'
        }
