I tried uninstalling and installing typescript and @angular/cli and deleted node modules, couldn't solve it. Any help how can I get rid off TIA!

【问题讨论】：

我怀疑这是由于使用了不兼容的 nodejs 和 angular-cli 版本造成的。请参阅此表以查看哪些版本可以协同工作：gist.github.com/LayZeeDK/c822cc812f75bb07b7c55d07ba2719b3

【解决方案1】：

你能分享你的 package.json 文件吗？我在开发依赖项中也看不到@angular-devkit/build-angular。如果不存在，请尝试通过以下命令安装它。

npm install --save-dev @angular-devkit/build-angular

【讨论】：

嗨，这对我不起作用！！更新了依赖项
@shekar，为什么 xlo 版本是 12 而其他人有版本 4。你只是升级了 cli 本身吗？版本不匹配也可能导致这种情况。

【解决方案2】：

我在尝试更新 Angular 版本后遇到了这个问题，并通过使用更新版本的节点解决了这个问题。
