Use correct path to the Composer bin directory.

Good:

%USERPROFILE%\AppData\Roaming\Composer\vendor\bin

Bad:

For Windows add

C:\Users\MyUserName\AppData\Roaming\Composer\vendor\bin 

... to directory by going to "My Computer" > "Properties" > "Advanced" > "Environment > Variables" > "Path".

Note: MyUserName is your pc username .

Restart your PC and it would work
