安装了 Ubuntu 的 Virtualbox 上的 Npm 安装问题

Question

只是想知道是否有人可以阐明 Virtualbox 机器上的 npm install 运行（安装了 Ubuntu v16.4）。我收到了这个错误的抱歉

Virtualbox 在安全方面限制了在共享目录中创建符号链接。所以你应该打开相关功能：

关闭 Virtualbox
将Virtualbox的安装路径添加到环境变量PATH
在cmd中执行以下命令

VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME(without the sf_ prefix)> 1
运行带管理员的 Virtualbox
