Question

我正在使用express-react-views包在serverside（NodeJs）中渲染react组件。我尝试渲染示例https://github.com/reactjs/express-react-views/tree/master/examples/dynamic中的react组件。但是当我尝试npm start时，它抛出了一个错误：错误：需要Babel“ ^ 7.0.0-0”，但已加载“ 6.26.3”。我尝试根据https://github.com/babel/babel-upgrade上的文档升级babel。但是仍然存在相同的错误。

如何解决此问题？请帮忙，因为我在此错误上遇到问题

我发现this post对下面的错误有很大的帮助。：）

Jest TypeError: Path must be a string. Received undefined

TypeError: Cannot read property 'cwd' of undefined

对我来说，以下解决方案有效。我希望它也对您有用！

yarn add babel-jest@22.4.3 --dev
yarn add jest@21.0.2 --dev
babel-core@^7.0.0-0 
                 ---> (Choose "7.0.0-bridge.0")

错误：需要Babel“ ^ 7.0.0-0”，但已加载“ 6.26.3”
