I can offer no help. But I have deep sympathy as I see the same problem.

Following this worked -

npm install @angular-devkit/schematics@0.0.45 @angular/cli --no-save
$(npm bin)/ng new my-new-app

[nilsfriess]

angular/devkit@e1f4356#diff-0dfbc02885bfb31a1e86e72520aad335

This is the commit in the schematics.ts file in the package @angular-devkit/schematics which is causing the problem

As this is just some refactoring, maybe it would be best to just go back.
See this issue on the devkit github: angular/devkit#380

See @maymarx answer in angular/devkit#380:

adding
"@angular-devkit/schematics":"0.0.42", "@angular-devkit/core": "0.0.23", to the package.json fixes the problems if you need a quick fix before the weekend

[slick-k]

Same issue here too guys and gals!

[derobiom]

Adding
"@angular-devkit/schematics":"0.0.42", "@angular-devkit/core": "0.0.23", to the package.json (dev dependencies) worked for me also.

[anankassis]

how you add those things you talked about ?!
exactly ???
like what to add ?? just "":"0.0.42", "": "0.0.23" ???

[iamviswajith]

i have the same issue, after adding "@angular-devkit/schematics":"0.0.42", "@angular-devkit/core": "0.0.23", to the package.json, i uninstalled angular cli and re installed it, but the same issue pops up

[gurgelv]

they are dependencies which can be added to the package.json of your project, and no "":"0.0.42", "": "0.0.23" is not enough. you need the full dependency names:
"@angular-devkit/schematics":"0.0.42", "@angular-devkit/core": "0.0.23"

In my case, I had no project to add these dependencies to (creating a new one now), so I had to follow @eclanrs's solution at angular/devkit#380:

npm i @angular-devkit/schematics@0.0.45 @angular/cli --no-save
