Answer 1

删除较新的文件，[browserslistrc]

这两个文件看起来完全相同。 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。 删除较新的文件 [browserslistrc] 后，此错误消失了。 我认为这也是 Mahendra Kumar 的意思。

Answer 2

注意，这是针对 Angular 项目的

您可以通过删除 browserslist error 和 .browserslistrc 文件来解决您的问题。

重新构建并运行您的应用程序

npm run start or yarn serve for my case

Answer 3

对我有用的简单解决方案 => 删除browserslist错误和.browserslistrc文件。

使用命令ng serve重新构建并运行您的应用程序
