Answer 2

I tried the other suggestions here, but ended up removing and re-installing Node.js and NPM.

Finally did the trick for me.

Answer 3

In my case @schematics/angular was completely missing from my package.json -- not sure what happened.

Running

npm i @schematics/angular --save-dev

Fixed the issue for me.

Hi Shivprasad Koirala,

I had the same problem as you but the solution did not do it for me. Frankly speaking, it is a little bit odd that re-installing node.js fixes your problem because it should not conflict with Angular/CLI but in any case, good for you.

For my case, the solution was a bit different. I had accidentally once tried to create a new project in my username's folder. This was wrong, and I had canceled the procedure but it seems like that it had created one or two things. So in that case the steps are:

1. Navigate to your username folder by opening windows explorer and typing in the address bar %HomePath%
2. Check if the file package.json and if the folder node_module exist. If so, you can delete them safely.

If you have a Linux, again you need to navigate to your home directory and delete both those entries.

Answer 5

I had the same problem after upgrading @angular/cli to version 6.1.5. Downgrading it to 6.0.8 solved problem.

My problem had been occurring during ng g lib ...

Answer 6

I had a similar issue. I tried explicitly installing @schematics/angular and setting my default cli collection using:

npm i @schematics/angular --save-dev
ng config cli.defaultCollection @schematics/angular

It did not work for me.

So instead, since I'm already using ngrx in my project, I opted for @ngrx/schematics as my default.

npm i @ngrx/schematics -D
ng config cli.defaultCollection @ngrx/schematics

That worked for me.
