Question

我有一个React应用程序，一年多来我还没有在本地启动。上一次启动该应用程序时，它运行完美。该应用程序今天仍将在Heroku的云中运行。但是我想在本地进行处理，并且在一年前运行良好时使用完全相同的package.json，现在在浏览器中失败，并显示以下错误消息：

TypeError: Cannot read property 'ReactCurrentOwner' of undefined

Screenshot Browser Error

我试图删除我的node_modules目录，并删除所有非yarn.lock文件，但是错误仍然存在。

我知道你们中的一个聪明人可以提供帮助。我将不胜感激。

可能您的一个依赖项进行了重大更改，您自己的package.json或您使用的一个依赖项都没有限制您依赖的依赖项的版本。我建议检查抛出错误的单个库，以确保为这些库传递的配置对于正在使用的版本仍然有效。

为什么我的React应用程序突然无法在本地工作？
