ng-xi18n error when importing angular component from node_modules

[reynardmh]

OS?

Mac OSX (Sierra)

Versions.

angular-cli: 1.0.0-beta.20-4
node: 7.0.0
os: darwin x64

Repro steps.

I created the app with CLI, copied the tsconfig.json from src to the root project so ng-xi18n can run. Here is the reproducible repo with detailed explanation of what I did.

https://github.com/reynardmh/bugdemo-angular-i18n

basically ng serve works, and the app runs, but ng-xi18n failed because I imported CoolComponent from node_modules. If I don't import the CoolComponent, ng-xi18n works fine.

This bug was originally posted in angular project, but @vicb thought this is a CLI issue and asked to reopen it in the angular-cli project.

angular/angular#12760

The log given by the failure.

[vicb]

The solution is that the CLI should provide a command wrapping ng-xi18n.

I discussed this with @hansl when an issue was created for project using sass (ng-xi18n would not have the right ResourceLoader).
I don't know the status.

@hansl could you please give a status update ? Thanks

[vicb]

@hansl told me that the new command will probably not be available before final - meaning sometime early next year.

He could help giving directions to someone willing to send a PR.

closing as a dup of #2201

[zhumingvictor]

2201 closed as a duplicate of this and this is close as duplicate of 2201. A dead loop.

@zhumingvictor #2201 isn't closed..?
