Non-Abelian chiral bosonization is reformulated in a gauge-invariant way. The Gauss constraint problem is solved and the gauge anomaly disappears by adding the Wess-Zumino action to chiral bosonization. Also the physical Hilbert space is constructed by making a tool of the Becchi-Rouet-Stora algorithm.
