We study scalability of quantum computing based on nanomechanical resonators (NAMRs), including the consequences of the effective next-nearest-neighbor spin-spin couplings induced by the NAMRs, NAMR frequency errors, and NAMR-spin coupling errors on the scalability of quantum computing based on NAMRs. We show the fidelity change of the quantum operation due to these errors numerically. Switchable interactions between NAMRs can be achieved by adding control gates. Based on this modification, we present a method to perfectly avoid the next-nearest-neighbor spin-spin couplings and compensate for the negative effects due to the frequency errors and spin coupling errors.
