Desired behavior

We have a dependency on @ngrx/schematics. ng new should be able to resolve it from globalNodeModules/@nrwl/schematics/node_modules/@ngrx/schematics

jason@Jason-PC-U:~/projects/work/temp/nx6workspace$ npm ls @ngrx/schematics -g
/usr/lib
└─┬ @nrwl/[email protected]
  └── @ngrx/[email protected] 

Mention any other details that might be useful (optional)

Workaround

The workaround for users is to also manually install the dependency globally

[hansl]

@FrozenPandaz This looks like an issue with the node resolver we use for resolving packages.

@meixuexiang this will never work, but the error message should be "cannot use an empty collection name" or similar.

[FrozenPandaz]

Thanks for taking a look @hansl.

That's unfortunate... Is there an open issue or should we make one? I dug through and could not seem to find the resolution code so I'm not sure which dependency it is.

Is there a workaround in the meantime? (One that the devkit can use to workaround the issue of the dependency I mean)

[markgoho]

Any update on this?
