Answer 1

刪除較新的文件，[browserslistrc]

這兩個文件看起來完全相同。 我在將項目更新到最新的 Angular 版本，然后從備份位置恢復項目時遇到了這個問題。 刪除較新的文件 [browserslistrc] 后，此錯誤消失了。 我認為這也是 Mahendra Kumar 的意思。

Answer 2

注意，這是針對 Angular 項目的

您可以通過刪除 browserslist error 和 .browserslistrc 文件來解決您的問題。

重新構建並運行您的應用程序

npm run start or yarn serve for my case

Answer 3

對我有用的簡單解決方案 => 刪除browserslist錯誤和.browserslistrc文件。

使用命令ng serve重新構建並運行您的應用程序

Answer 4
