After installing, while ember server this came up...

[vojtechmares]

Hi,

today I took a look into an EmberJS and I wanted to start working on my first app, but after running ember new <app name> and trying to see if it works usign ember server the following error has been occured:

$ ember server

Running without permission to symlink will degrade build peformance.
See http://ember-cli.com/user-guide/#windows for details.

Hey! I'm no expert but it seems to me that you lack the config file for eslint.
Error: No ESLint configuration found.

Do you have a file named .eslintrc.js or similar in your app's root folder? It should've had been created automatically when ember new <app> was run as far as I concern.

@theacastus this is working fine for me here. as @theLastLivingGhost mentioned it seems like you are missing an .eslintrc.js file in your project folder that should have been created by ember new. could you check if that exists?

[vojtechmares]

Oh, it is fine now. The file .eslintrc.js was missing. Maybe I have accidentaly touch that file while moving the stuff on disk or remove something... nevermind.

I tried ember new <something> and it works just fine.

So this issue is my bad and I have no idea how it happened. But it is fine.

Closed.

ps: thanks for your answers!
