【问题描述】：

我正在尝试在 macos 上安装 nodejs 版本 10.x，以及 angular cli。但是每次尝试时，我都会收到有关 ng 与 node 版本不兼容的错误。

我一直关注这里的帖子 Unable to get Angular CLI version, though all the requirements are installed?

我在安装过程中没有收到任何错误，但我一直收到错误：

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 Angular 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

【问题讨论】：

Node.js 10.x 不受支持。就像，不仅 Angular 不支持，而且 Node.js 项目也不支持。更新到 12.x、14.x 或 16.x（在撰写本文时是受支持的版本）。

【解决方案1】：

使用命令npm install -g @angular/cli 时，您将安装最新版本的angular，它需要12 版本的node。

因此，您需要将节点版本更新为 12 或通过向安装脚本指示版本来安装以前版本的 angular

npm -g install @angular/cli@8.3.25

【解决方案2】：

您已经在使用nvm，尝试使用 nvm 安装 node 最新版本，如下所示：

nvm install --lts

检查最新的 nvm 版本，它应该大于12。原因是角度版本 8 依赖项在较低版本的节点上运行不佳。并且还建议保持版本更新以防安全漏洞。

这会列出版本，选择版本v12.14 or v14.15或LTS

nvm list
.....
nvm use v12.14

在此之后使用link 安装 Angular 版本 8+。
