这个错误以前遇到过，关键词 symlink permission，意思是没有创建超链接的权限；
我今天这种环境经常遇到这种问题（Windows宿主机器+Vagrant Ubuntu Host机器）
解决方案
给 npm install 添加参数 --no-bin-links
ganiks@ganiks-ubuntu-trusty-64:/ganiks/parse-server$ npm install -g mongodb-runner parse-server --no-bin-links + mongodb-runner@4.7.1 + parse-server@3.1.3 added 563 packages from 403 contributors in 28.79s ganiks@ganiks-ubuntu-trusty-64:/ganiks/parse-server$ ls /usr/local/lib/node_modules/ -l total 12 drwxrwxr-x 6 ganiks ganiks 4096 Jan 17 10:23 mongodb-runner drwxr-xr-x 10 root root 4096 Jan 17 08:51 npm drwxrwxr-x 7 ganiks ganiks 4096 Jan 17 10:23 parse-server

One scenario that I can think of is working with a virtual machine (i.e. vagrant w/ virtual box or VMware) on windows host.
You can't translate symlinks to a synchronized folder on Windows share, so you will need this option to go around it.Use it for any filesystem that doesn’t support symbolic links.
简言之，所有不支持软链接的磁盘系统都需要用到这个 --no-bin-links
