Repro steps

• Run git clone https://github.com/mprahl/angular-cli-9671-reproducer.git
• Run cd angular-cli-9671-reproducer && npm install && ng serve

Observed behavior

ERROR in ./src/app/app.module.ts
Module not found: Error: Can't resolve 'reproducer/hello/hello.component' in '/path/to/angular-cli-9671-reproducer/src/app'

Desired behavior

The imports should work as they did in v1.6.x.

Mention any other details that might be useful (optional)

The following commit broke this functionality: https://github.com/angular/angular-cli/commit/29aa274b6721c1399ca2baca18565b21254fb3f0

Running angular-cli with commit https://github.com/angular/angular-cli/commit/29aa274b6721c1399ca2baca18565b21254fb3f0 reverted works as expected.

Is this issue still present in angular cli 6.0.0? Or there is some new solution? What is the correct way to have imports like import { } from "shared" instead of import { } from "../../../../../shared"?

I tried angular cli 6.0.0 and it seems the problem is still here.

EDIT:

I was mistaken, after upgrade to angular-cli 6.0.0 everything works OK now.

I am having the same issue as well, but in my case we have one app (styleguide) that is outside of the src folder and building that app fails with cli 1.7.3, while it works with 1.6.x. Seems like baseUrl option in tsconfig.json is partly respected? And yes, almost all our paths are relative to root directory.

EDIT: I’ve got it to work for js/ts files with this:

...
"baseUrl" : ".",
"paths": {
  "*": [ "node_modules/*", "source/*", "styleguide/*"]
}
...

But now it breaks for html files which we are still requiring in older angularjs files (we are in a process of upgrading).
