我按照以下步骤更新了我的angular项目。
npm cache clean --force
npm uninstall @angular/cli@latest @angular/core@latest
npm install -g @angular/cli@latest @angular/core@latest
之后，我删除了node_modules目录，并执行npm ci
最后npm install node@latest
在所有这些之后，我开始了这个项目ng serve --host 192.168.1.155
但我得到了以下错误：

有人能帮我吗？现在我无法运行该项目。
非常感谢！
angular团队做了很多工作来帮助版本迁移，并且有一个有用的angular Update Guide，我发现它很有用(虽然不完美(，在许多主要版本上更新我的应用程序时非常有用。
我注意到，在他们从11更新到12的说明中，他们指出你应该：
ng update @angular/core@12 @angular/cli@12
我建议您恢复正在进行的更改，并利用这些资源进行更新。
我建议恢复到版本11-当我升级到版本12时，遇到了很多错误，尤其是scs，我最终评论掉了我的一些东西。。。v12的构建也需要一段时间。
如果你在版本11-不要太快升级
尝试删除yarn.lock并重新安装你也可以参考这个链接，https://classic.yarnpkg.com/en/docs/yarn-lock/
