As this answer explain, const support is not enabled by default in node.js version 0.10 and require --harmony flag if you want to use it.
As this version of fs-extra package use const keyword in his index.js file, you got this error.
You can have a look at this compatibility table for a summary for const and let support by version.
Just upgrade your node.js version to solve this issue.
Also, I don't think it is a good idea to launch gitbook as root user.
