I had the same issue - it turned out that i was using a deprecated angular-cli instead of  angular cli  The latter was used by my dev team and it took me some time to notice that we were using a different versions of angular-cli

I had the same error message  But the cause and solution are slightly different  When I ran  ng -v  it showed different versions for angular-cli  1 0 0-beta 28 3  and  angular cli  1 0 0-beta 31   I re-ran   npm install -g  angular cli   Now both show a version of 1 0 0-beta 31  The error message is gone and  ng serve  now works   Yes - it was  angular cli that I re-installed and the angular-cli version was updated

Just include this in the package json in devDependencies section   angular-cli    1 0 0-beta 25 5    Not compulsory to install it if you have another vresion of cli installed globally    I got this issue when I worked with angular2  amp  4 at a time with different project  So angular4 - need angular-cli latest and angular2 need angular-cli the above version
