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对在 Virtualbox 机器上运行的 npm install 有所了解（安装了 Ubuntu v16.4）.. 我很抱歉这个错误

为了安全起见，Virtualbox 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：

1. 关闭虚拟机

2. 将Virtualbox的安装路径添加到环境变量PATH中

3. 在cmd中执行下面的命令

   VBoxManage setextradata <VM_NAME> VBoxInternal2/SharedFoldersEnableSymlinksCreate/<SHARE_NAME(without the sf_ prefix)> 1

4. 以管理员身份运行 Virtualbox
