The compiler is correctly diagnosing an error.  The derived class needs a base
class constructor to call.  The keyword "super", when used in a constructor,
denotes a constructor of the base class.

class B : A {
    this (int i) {

If no call to super is present, then it looks for a default constructor and
calls that.  Hence if there's no default constructor in the base class, then
you must call super when calling the derived class.
