Like the error says, add babel plugin @babel/plugin-proposal-class-properties

Post edited, I had forgotten to show package.json. This error is not related to your repository plugins? by default, we can use statics in the react.js. Error is shown when I use withTranslate. @rmdort please help me ..

[kindslayer]

Hey !!

[rmdort]

I think you are loading the plugin from src directory.

Change import {withTranslate} from "react-redux-multilingual/src"; to import {withTranslate} from "react-redux-multilingual"
