You are attempting to run Meteor as the "root" user. Error with published meteor @1.4.2

Seems like meteor-tupperware is affected by this as well:

A build step failed: The command '/bin/sh -c sh /tupperware/scripts/on_build.sh' returned a non-zero code: 1

You are attempting to run Meteor as the "root" user. If you are developing, this is almost certainly *not* what you want to do and will likely result in incorrect file permissions. However, if you are running this in a build process (CI, etc.) or you are absolutely sure you know what you are doing, add the `--unsafe-perm` flag to this command to proceed.
