无法安装正确的 Angular/CLI 版本

Question

我正在尝试在 macos 上安装 nodejs 版本 10.x 以及 Angular cli。但每次我尝试时，都会收到有关 ng 与节点版本不兼容的错误。

我一直在关注这里的帖子 Unable to get Angular CLI version, while all the required required are displayed?

我在安装过程中没有收到任何错误，但我不断收到错误：

adminMini:client admin$ ng -v
Node.js version v10.24.1 detected.
The Angular CLI requires a minimum Node.js version of either v12.14 or v14.15.

Please update your Node.js version or visit https://nodejs.org/ for additional instructions.

这就是我安装角度的方式：

adminMini:client admin$ nvm use 10
Now using node v10.24.1 (npm v6.14.12)

adminMini:client admin$ npm uninstall -g @angular/cli
removed 235 packages in 2.001s

adminMini:client admin$ nvm use 10
Now using node v10.24.1 (npm v6.14.12)
adminMini:client admin$ npm install -g @angular/cli

使用该命令时，npm install -g @angular/cli您将安装最新版本的 Angular，它需要版本 12 的 Node。

因此，您需要将节点版本更新到 12 或通过在安装脚本中指示版本来安装以前版本的 Angular

npm -g install @angular/cli@8.3.25
