Can you please post the results of running:

npm ls rxjs

Also, could you post the repository to github and share?

I have the same error :(

I was having the same error. This was the result from npm ls rxjs:

├─┬ @angular/cli@1.6.0 │ ├─┬ UNMET PEER DEPENDENCY @angular-devkit/schematics@0.0.41 │ │ ├── UNMET PEER DEPENDENCY @angular-devkit/schematics@0.0.40 │ │ └── rxjs@5.5.5 │ └── rxjs@5.5.5 ├── UNMET PEER DEPENDENCY @angular/compiler@5.1.0 ├── UNMET PEER DEPENDENCY @angular/core@5.1.0 └── rxjs@5.5.5

I ran: npm update

And now it works.

neo-clon commented 6 years ago

Thanks! I ran yarn upgrade and now works :)

Output of npm ls rxjs:

test-project@0.1.0 C:\Users\Enzo\WebstormProjects\test-project
+-- @angular/cli@1.6.0
| `-- rxjs@5.5.5
`-- rxjs@5.5.0

As suggested, I ran npm update, but this had no effect for me.

@Brocco I can not publish the original repo, but I created a new project and copied the exact dependecies:

https://github.com/evolkmann/test-ng-generate

In this particular setup, the error happens and can be reproduced.

ng -v prints:

After running yarn upgrade and then trying to generate a module, I get:

yarn run v1.3.2
$ ng g m MyModule --dry-run
Error: You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.
