This is what I get when trying to use tinker helper.

ErrorException (E_WARNING)
exec(): Unable to fork [open "tinkerwell://?cwd=QzpcT3BlblNlcnZlclxkb21haW5zXGRldi5pbXBlcmF0dG9yLnJ1&scope=YTox...

I think reason is that Windows doesn't have "open" command.
But I don't see any info about this package is for Mac only.
