Delete the newer file, [browserslistrc]删除较新的文件，[browserslistrc]
These two files appear identical.这两个文件看起来完全相同。 I encountered this when I updated my project to the latest Angular version, then restored the project from a backup location.我在将项目更新到最新的 Angular 版本，然后从备份位置恢复项目时遇到了这个问题。 After deleting the newer file [browserslistrc], this error went away.删除较新的文件 [browserslistrc] 后，此错误消失了。 I think this is what Mahendra Kumar was getting at, too.我认为这也是 Mahendra Kumar 的意思。

Notice, that was for Angular Project注意，这是针对 Angular 项目的
You can solve your problem by removing both browserslist error and.browserslistrc files.您可以通过删除 browserslist error 和 .browserslistrc 文件来解决您的问题。
re-build and run your app重新构建并运行您的应用程序
npm run start or yarn serve for my case npm run start or yarn serve for my case
