从10到11的角更新给出了错误

Question

实际项目是版本9。从版本9到10的升级成功完成。当我检查Angular版本ng V时，它将显示版本10，并且包装文件还使用版本10进行了更新。但是，从10升级到11时，我会给我以下错误。

运行以下命令以从版本10

ng Update @angular/core @11 @angular/cli @11 -force

获取以下错误

ps：****是否与文件夹名称和项目名称有关

Answer 1

遵循它所说的；您已经在使用- 强制，但是您会发现有很多软件包迫使您需要- legacy-peer-deps flag也是如此。

两者都运行。

我已经升级了几个项目，现在几乎所有这些项目都需要旧版标志，因为许多二次没有更新。
