I am new in angular2. I have downloaded angular 2 project and tried to setup. I installed angular cli 1.0.0-rc.2 and when I am doing ng serve it is showing the below error:
Cannot read property 'config' of null TypeError: Cannot read property 'config' of null at Class.run (D:\Sumit\AgulaNew\admin\node_modules\@angular\cli\tasks\serve.js:22:63) at check_port_1.checkPort.then.port (D:\Sumit\AgulaNew\admin\node_modules\@angular\cli\commands\serve.js:103:26) at at process._tickCallback (internal/process/next_tick.js:188:7)
