As it appears to be some issue with node-pre-gyp I tried installing module node-pre-gyp globally. Issue was reproduced.

Tried taking ownership as suggested in Fixing Npm Permissions and installing once again:

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
npm install node-pre-gyp -g

Success.

Searching online brought me to Symbolic links with .. result in protocol error on vboxsf + 5.0.4:

• VBox 5.0.6 contains the fix.

Note: my VBox is apperntly old: Version 5.0.16 r105871

This doesn't sound like an issue with this repository?
