I just updated Meteor up to the latest version and face this issue: https://github.com/zodern/meteor-up/issues/729
Maybe someone here can help me very quickly in the github topic. It is pretty important this gets resolved asap.
I resolved it for now by downgrading MUP to 1.3.1
I haven’t used MUP in forever, so I’m probably not the best troubleshooter. It would be helpful to post the actual version of Meteor you’re using, though. The “latest” version could refer to stable, RCs, betas, etc.
Regarding your exact error, looks like something’s not in love with that es6 syntax?
Meteor 1.5.2.
MUP version 1.3.2.
MacOS 10.12.6
Node v4.8.2 locally/ v4.2.6 server
