Error when trying npm start

[memento]

Hi thanks for your work. I have the following error with your project. I wonder if you had to face it :

webpack: Failed to compile.

[mohsin917]

Hi, I am having the same issue.....

[TwanoO67]

Hello guys,

Did you try compiling using docker ?

[harangozop]

Hi @TwanoO67

I have the same issue, and I didn't try docker, I'd like to use on windows without docker (for now) just with the pure ng cli.

Do you have any suggestion?

[TwanoO67]

The problem is introduced by @angular 2.4.10 going back to 2.4.8 solve.

We should look more in depth in what is the issue with those spec files. But for the moment I provided the "yarn.lock" file to lock the dependencies. So you can fixe that by doing a "yarn install" instead of "npm install"

[TwanoO67]

Any confirmation ? is it ok for you guys @memento @mohsin917 @peter9208 ?

[harangozop]

@TwanoO67 Thanks for ur help, I solved temporarily by deleting the spec.ts files.

I found something you might be interested in:

• http://stackoverflow.com/questions/38895087/tests-are-failing-after-angular-2-rc5/38895372
• http://stackoverflow.com/questions/38871261/error-angular-core-testing-has-no-exported-member-beforeeach-after-upgradi

I am still looking for what happened with TestComponentBuilder because it isn't in core/testing module anymore. But the beforeEachProvider to TestBed seems like working.

[TwanoO67]

I'm closing this one because it's not relevant with the new ng4 version. But we should definitly have some test back, so if some of you know how to get those working i would be glad to help
