Node-sass: EPROTO/ETXTBUSY errors while installing

[amarbham]

Cannot install node-sass using npm install from package.json.

node v - 5.0.0
npm -v 3.3.6
node-sass 3.8.0

I can get around this by doing npm install node-sass --no-bin-links seperately but this doesn't fix the issue.

What platform is this? What are the filesystems you build on (NFS, SMB, ZFS, ext3, etc.)? Are you trying to build on some kind of shared drive between host and virtual (Vagrant) environment?

See https://github.com/npm/npm/issues/9901, one advice is to update VirtualBox or to run vagrant up as the system administrator if on Windows in order to create symbolic links (symlinks).

Running Wndows CLI as administrator and doing npm install without --no bin-links works thanks
