当我尝试通过以下方式安装 CLI 时收到 npm 警告：npm install -g @angular/cli:
C:\Users\myuser>npm install -g @angular/[email protected]

我做错了什么？或者说怎样才能解决呢？谢谢！
我本来希望安装 Angular CLI。
看起来 Angular CLI 没有正确安装，或者您系统的 PATH 环境变量不包含全局 npm 目录。以下是解决此问题的方法：
检查npm路径配置并运行以下命令来检查npm安装全局包的位置：
npm config get prefix
确保此命令返回的路径包含在系统的 PATH 环境变量中。
将npm路径添加到系统环境变量中： 打开系统上的“环境变量”设置。 添加 npm 全局路径（例如 C:\Users\your_user\AppData\Roaming pm) 到 PATH 变量。
重新安装 Angular CLI：卸载 CLI，清除 npm 缓存，然后重新安装：
npm uninstall -g @angular/cli
npm cache clean --force
npm install -g @angular/cli
验证安装：运行以下命令来验证安装：
ng version
如果仍然无法识别 ng 命令，则 npm 本身可能存在问题。考虑更新 npm 或重新安装 Node.js.
