我正在尝试测试反应虚拟化。我使用了download-zip
文件。当我npm start
在 react-virtualized-master 中运行时,它不会呈现任何具有以下错误的内容。任何人都可以帮助修复这个错误吗?
反应错误:
Uncaught Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. Check the render method of `Application`.
