我用 create-react-app 引导了我的应用 程序 ，当我运行我的应用程序时，它会编译并带有警告，并在浏览器中引发错误。
编译时出错

我已经尝试研究了它，并且它是由 moment-js引起 的错误，但我没有使用该模块，也未安装。
可能是什么问题呢？
发生这种情况的原因是， 当下 已将新版本从 2.24.0发行到2.25.0
执行以下步骤来解决此问题：
步骤1： 更改版本 （在您的情况下，只需在 package.json中 的依赖项中添加 “ moment”：“ 2.24.0” ，因为在 package.json 中看不到它）
"moment": "2.24.0", "moment-timezone": "^0.5.28",
第2步： 如果您使用的是 yarn， 请在package.json文件中添加分辨率，如下所示
"dependencies" { "moment": "2.24.0", "moment-timezone": "^0.5.28" }, "resolutions": { "moment": "2.24.0" },
