Repro steps

using ng g c
get error first 'Cannot read property 'NullLogger' of undefined. and I have two versions of webpack, both the same (3.10.0) one under the CLI and one not. When I address that issue I get ERROR: cannot read property 'dasherize' of undefined.

Desired behavior

Mention any other details that might be useful (optional)

resolved that issue with a lot of uninstalling and re-installing and only issue remaining is when running ng generate component get error 'cannot read property 'dasherize' of undefined. Any direction would be helpful; there seems to be nothing about this out on stack

I am running into similar issue.

First, to get ride of below error, I changed @angular-devkit/core from 0.0.27 to 0.0.29.

core_1.PriorityQueue is not a constructor

I resolved that but now have below error on ng generate component unit-testing-example

Error: Cannot read property 'dasherize' of undefined
Cannot read property 'dasherize' of undefined

I tried to update angular cli to latest 1.7.0 but it doesnt help.

[OrganicCat]

I'm getting the same thing right now.

(ran this) ng g c cats/component-palico

Error: Cannot read property 'dasherize' of undefined

[JakobSegerslatt]

I fixed it by updating;

@ angular-devkit/core
from "0.0.23" to "0.4.2"

@ angular-devkit/schematics
from"0.0.42" to "0.4.2"
