Unable to build when adding angular2-logger to angular-cli managed project

[jbruinink]

If I build my angular-cli project which has the angular2-logger dependency, I get the following error:

jeroen@host:~/example$ ng build

The error can be reproduced by doing the following:

npm install -g angular-cli
ng new example
cd example
npm install -save angular2-logger

Then edit the src/app/app.module.ts and add the import:

import { Logger } from 'angular2-logger/core';

and add the provider:

  providers: [Logger],

Same issue for our project

[Zeemee7]

Same for me, it happened with the update of angular-cli 1.0.0-beta-24 to 1.0.0-beta-25.5. It worked with beta-24.

[jbruinink]

I tried downgrading to angular-cli 1.0.0-beta.24 and I get the same error.

sudo npm uninstall -g angular-cli
sudo npm install -g angular-cli@1.0.0-beta.24
ng new example
cd example
npm install -save angular2-logger
[edit app.module.ts]
ng build

[k1ng440]

we have the issue. please fix

[rodneyjoyce]

Was working fine with AngularCLI Beta .21. Upgraded to .25.5 and this error occurs.

Interestingly, I see that the core team have implemented a logger in 25.5 CLI : angular/angular-cli@e3b48da

[eservent]

I have the same issue (worked with beta 24) and I found a way to avoid the problem.
I replace this import :
import {Logger, Options as LoggerOptions, Level as LoggerLevel} from 'angular2-logger/core';
By these imports :
import {Level as LoggerLevel} from 'angular2-logger/app/core/level';
import {Logger, Options as LoggerOptions} from 'angular2-logger/app/core/logger';

Hello all,

Really sorry you are all running into these issues but I won't be making any changes based of a beta product, when you use a beta software you are bound to have issues eventually and things will be changing, I can't fix it everytime they brake something.

If someone has a pull request with the fix I don't mind taking a look at it.

[rodneyjoyce]

Fair enough - good point

[rodneyjoyce]

The fix by @eservent seems to work for me too - thx

[bruderol]

workaround by @eservent is working - but it is annoying to have to adjust all the imports all the times, because the IDE will not use that import automatically (at least intelliJ doesnt). I think it is bad that they broke that in the CLI - maybe we should file it as a bug there?

[langley-agm]

@bruderol certainly worth a try.

[bruderol]

So could please someone open a bug at Angular-CLI, who has some more insight into the details of this? Thanks!

[chunghha]

Probably this already fixed in Angular-cli, angular/angular-cli@e91552f

So might wait for next release of the cli or if you are like me then I found an alternative logger for AOT support here.
https://github.com/noemi-salaun/ng2-logger

@langley-agm I hope you wouldn't mind another logger linked here. Just info for others.

[langley-agm]

@chunghha not a problem !

[Lyoko-Jeremie]

i have the same problem in @angular/cli 1.0.0-beta.30 with AOT build.
