Angular 2 Cannot read property ‘config’ of null

I have a issue with Angular 2. When i want to start server it get this:

$ ng serve
Cannot read property 'config' of null
TypeError: Cannot read property 'config' of null
at Class.run (C:\Users\Damien\Desktop\application\node_modules\@angul ar\cli\tasks\serve.js:22:63)
at check_port_1.checkPort.then.port (C:\Users\Damien\Desktop\application\node_modules\@angular\cli\commands\serve.js:103:26)
at process._tickCallback (internal/process/next_tick.js:103:7)

I reinstalled CLI and nothing else is working. I could be something with json file?
