Account-Base Module Autorun Issue


We are upgrading our Meteor project 1.5 to 1.8, everything works fine on our dev env. However, when we deploy the app to our test web server, we would get the following error.

Uncaught TypeError: o.autorun is not a function

The error is from Account-Base module, Meteor.autorun is not a function. How can I fix this?
