1.5.1 update from 1.5 gives a lot of errors

Apologies, I had posted this as a reply in a similar thread, then realized the thread had been marked solved. I’ve removed my reply and am re-posting as new in hopes of getting some guidance.

When I recently updated from 1.5 to 1.5.1 as suggested when I ran meteor from an app I’m working on, it updated the meteor version as well as many other packages I have installed.

Once I got the errors below I tried to downgrade materialize back to 0.98.2 from the 0.100.x version it updated to, but it wouldn’t take. Not sure why.

At any rate, now when I run my app, my page doesn’t load the view and I get the following errors in the console in Chrome.
