Installing node-inspector through Vagrant's provision file issue

I can't successfully install node-inspector through Vagrant up provisioning.

My provisioner file has these commands:

• npm install -g n --unsafe-perm
• sudo n v8.0.0
• sudo npm cache clean -f
• sudo npm install -g node-inspector --unsafe-perm

However, the section for installing node-inspector keeps erroring out:

I'm using Vagrant's VM.box "urban/trusty64-node". My host is Mac OS X (vagrant is install on).
