Add me to the list of people getting this error. I'm simply following the install steps shown here. Using Angularfire2 4.0.0-rc.2
firebase 4.3.0

[szaske]

I found a solution to this problem. I upgraded to the newest node (8.4) and latest angular/cli...and that resolved the problem. Previously I was using the older angular-cli.
