Upgrade to 1.5 bundle-visualizer error

help

Hi,
I upgraded my project to 1.5 and added bundle visualizer but when i start my app i get the below error. I am using Angular 4. This error goes away when i remove package. What am I missing?

Unhandled Promise rejection: Cannot find module 'assert' ; Zone: <root> ; Task: Promise.then ; Value: Error: Cannot find module 'assert'

Had to do this to make it work…

meteor npm --save install assert

I added the dev option to avoid adding the assert package to the production bundle.

I’m using Meteor 1.6.1.
This should be fixed…

meteor npm --save-dev install assert

Just ran into this in Meteor 2.7.1.

Using the below fixes the issue:

meteor npm --save-dev install assert

I don’t see it on a fresh project install of Meteor so I’m not sure what the underlying cause is. Reviving this thread in case someone else comes across the same issue and has ideas.
