警告：道具类型失败：道具“商店”在“提供者”中标记为必需，但其值为“未定义”。在提供者中

如何解决警告：道具类型失败：道具“商店”在“提供者”中标记为必需，但其值为“未定义”。在提供者中？

您store默认导出：export default store;

您需要通过以下方式导入它： import store from ’./Store/Store’

有两种出口：

export myVar必须用进口{和}export default myVar必须不带{和导入}

这对于从文件导出/导入多个变量/函数很有用：

// file.jsexport a;export b;export default c;//otherfile.jsimport c, { a , b} from ’./file’;解决方法
