Reactjs ERR_INVALID_ARG_TYPE

Question

那里！我从themeforest购买了一些模板，预览版一切正常，但使用新版时出现错误，例如

> TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type
> string. Received type undefined
>         at validateString (internal/validators.js:125:11)

我相信模板不应该有这个错误，但我仍然有它。可能是什么问题呢？

Answer 1

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

要解决此问题，只需升级到 "react-scripts": "^3.4.0"

1. 覆盖现有的"react-scripts": "^3.x.x"与"react-scripts": "^3.4.0"你的package.json
2. 删除您的节点模块
3. 最后运行npm install或yarn install进入您的命令提示符。

我希望它会解决它。
