webpack-dev-server config.js Cannot find module

Error: Cannot find module，webpack-dev-server --config 報錯找不到模塊

webpack-dev-server 設置 webpack.config.js

webpack-dev-server --config config/webpack.dev.js

報錯：

Error: Cannot find module 'F:\jutils\dist\config\webpack.dev.js'

記得加上級路徑（相對路徑）

webpack-dev-server --config ../config/webpack.dev.js
