安装 Angular 不支持的引擎，OSX

我正在重新安装我的 MacBook。当我安装 (npm install -g @angular/cli) Angular 时，我收到以下消息。知道为什么吗？我怀疑 nom 版本，但我附带了节点......

更新 - 2021 年 2 月 25 日

npm 7.5.6或更高版本现在可以使用angular-cli版本9.1.15, 10.2.3, 11.2.2, 12.0.0-next.2或更大（在每个主要版本内）按照这条评论 https://github.com/angular/angular-cli/issues/19957#issuecomment-786177315来自 Angular 团队

原始消息 - 2021 年 2 月 7 日

截至撰写本文时，npm 7 尚未完全支持angular-cli as per 这个 GitHub 问题 https://github.com/angular/angular-cli/issues/19957#issuecomment-773569798

我在 Windows 上也收到相同的警告current: { node: 'v15.4.0', npm: '7.5.2' }

当我运行时，Angular CLI 返回警告ng new与 npm 7 并提供了解决方法

npm version 7.5.2 detected.
The Angular CLI currently requires npm version 6.

Please install a compatible version to proceed (`npm install --global npm@6`).

npm 7 最近于 2021 年 2 月 2 日全面发布 https://github.blog/2021-02-02-npm-7-is-now-generally-available/
