Thank for great boilerpalte!!

At some point I was not able to create package and I'm getting the next error:

ERROR in unknown: Invalid number (70027:15)

When checking the bundle.js at this line the code there is:

function mkdirP (p, opts, f, made) {
   ... 
    if (mode === undefined) {
        mode = 0777 & (~process.umask()); // the issue is with the octal 0777 that should be 0o777
    }
   ....
}

Any idea how to fix it?
