Windows 11无法安装Angular 16，始终默认安装15.2.9求助

问题现象 #

在Windows 11系统中尝试安装Angular 16，无论执行各类清理重装方案，最终安装的都是Angular 15.2.9；但MacBook上可正常安装Angular 16。

已尝试操作 #

• 全局卸载@angular/cli
• 执行npm cache clean --force清理缓存
• 指定安装@angular/cli@latest版本
• 尝试执行ng update @angular/cli @angular/core，但提示需在工作区内运行

解决方案 #

1. 清理全局npm残留文件 #

• 执行npm list -g @angular/cli确认全局包安装位置
• 找到npm全局目录（通常为C:\Users\[你的用户名]\AppData\Roaming\npm），删除其中的ng.cmd、ng.ps1文件，以及node_modules下的@angular文件夹

2. 检查并更新系统环境变量 #

• 打开系统环境变量设置，检查PATH中是否存在指向旧Angular版本的路径，如有则移除
• 确保PATH中优先包含当前npm全局目录的路径

3. 指定版本重新安装 #

• 彻底清理后，执行npm install -g @angular/cli@16直接指定安装Angular 16版本
• 安装完成后关闭当前PowerShell窗口，重新打开再执行ng version验证

4. 验证Node.js架构兼容性 #

• 当前系统显示为win32 ia32，Angular 16对32位Node.js支持有限，建议卸载现有32位Node.js，重新安装64位版本后再尝试安装Angular
