[eugenotop]

this is don't work for me #35 (comment)

[domi7777]

I had the same issue, I figured my angular & angular-cli dependencies didn't have the same version as ngw. After I changed it, it built correctly (I enforced specific version 6.0.7 by removing the ^)

[ivanpadavan]

It's not intended to sync precisely versions of ngw and angular. But thank you for the clue! Cannot understand what causes this issue
