We construct a multi-component interacting hard-core anyons model with SU(N) invariance and obtain the exact solutions of the systems by using the nested algebraic Bethe ansatz method with anyonic grading. We find that the grading parameters enter the Bethe ansatz equations as the gauge potentials, and the magnetic flux-like effects are different in the different rapidity sectors. Our results cover the interacting multi-component bosonic or multi-component fermionic models with SU(N) symmetry. In the system, the effective interactions among each component can be tuned by the grading parameters which do not break the integrability, while the integrability of conventional multi-component bosons or fermions requires that all the interactions are equal. The results will be useful to theories and experiments of the cold atomic systems.
