如何修复 npm 错误！解决时：@angular-devkit/build-angular@15.0.4 npm ERR！找到：@angular/compiler-cli@12.2.2？

Question

我正在尝试在本地更新 Angular cli 版本，但是每次运行以下命令时，我都会收到以下错误：

npm uninstall --save-dev angular-cli。（尝试按照此处显示的步骤进行操作）

如果我尝试运行命令：npm install，我也会得到以下信息：

无论我尝试什么，我都会收到相同的错误消息，并且我在网上没有找到任何有价值的东西。我怎样才能让它发挥作用？

Answer 1

尝试以下命令

npm 安装 --force

ng 更新 @angular/core@15 @angular/cli@15 --force

还要输入此命令，这样您就不必再次使用 --force。这应该可以解决依赖冲突

npm 配置设置legacy-peer-deps true
