我相信模板不应该有这个错误，但我仍然有它。可能是什么问题？

【问题讨论】：

您需要提供代码。从表面上看，它在函数validateString 中抱怨validators.js，其中path 参数未定义。

【解决方案1】：

您可以查看此链接https://github.com/ionic-team/ionic/issues/20503

要解决这个问题，只需升级到"react-scripts": "^3.4.0"

在你的 package.json 中用"react-scripts": "^3.4.0" 覆盖现有的"react-scripts": "^3.x.x"
删除您的节点模块
最后在命令提示符中运行 npm install 或 yarn install。

我希望它能解决它。
