Unable to install bluetooth-hci-socket

[red9ueen]

I'm engaged in programming a Sensortag App in Node.js with VS2015. At first, I was trying to install bluetooth-hci-socket but failed.

Could you give me a clue to fix it, please? Thank you in advance.

Error messages are following.

@red9ueen could you please try to upgrade your Node.js and/or npm versions to a later version.

I think it related to https://github.com/nodejs/node-gyp/issues/629

[red9ueen]

Thank you a lot for your advice. Updating Node.js to v7.0.0-pre8 worked!
