npm install vux-loader-- try save


you don't even install jquery


look at your package.json dependency on this vux-loader . As for why this error occurs, it is recommended that you delete the node_modules file and reinstall it.


webpack the version of this package is too low, use webpack4.x .

because webpack-dev-server when v3.1.14 , it supports webpack4.x. So there is an error in the addHooks method.
