我要评论一、安装
angular cli 脚手架安装命令：
npm install -g @angular/cli
在安装前请确保自己安装nodejs环境版本为v18及以上，否则会因node版本问题导致项目无法正常运行。
脚手架安装后，已提示了当前node版本必须为18.13.0或大于20.9.0版本：
在node版本不一致情况下，创建项目会提示node.js版本必须为v18.13，如下图：
二、匹配版本
本人电脑上使用的node版本为v16，在不升级node版本情况下，可以考虑降低@angular/cli版本，地址：releases · angular/angular-cli · github
2.1 安装命令
在releases中找到对应版本进行安装，命令如下：
npm install -g @angular/cli@16.2.6
此时则没有版本问题提示了，如下图：
2.2 创建项目
