@zoutong123 You can’t use v3 of @material-ui/core with v4 of @material-ui/lab please upgrade core. Also it looks like you might be importing the slider with @material-ui/lab/Slider/Slider we don’t support that level of importing please use @material-ui/lab/Slider or import {Slider} from@material-ui/lab`
