问题描述 #

Ubuntu系统已安装Node.js v12.22.9，执行nvm install v10.22.0安装旧版本时，反复出现权限拒绝错误，具体错误信息如下：

解决方法 #

• 修复nvm缓存目录权限
  错误核心是当前用户对/home/wand/.nvm/.cache目录没有写入权限，执行以下命令修改目录所有者：

  sudo chown -R $USER:$USER /home/wand/.nvm/.cache
  

  执行完后重新运行nvm install v10.22.0即可。

• 清理缓存后重试
  如果权限修复后仍有问题，先清空nvm缓存再安装：

  nvm cache clear
  nvm install v10.22.0
  

• 手动下载安装（备选方案）
  若上述方法无效，手动下载安装包后指定路径安装：

  1. 下载node-v10.22.0-linux-x64.tar.xz到本地（比如~/Downloads目录）
  2. 执行命令指定本地文件安装：

     nvm install v10.22.0 --node-dir ~/Downloads
