Question

尝试捆绑安装较旧的项目时出现此错误。我被卡住了，不确定如何解决。我在多个项目中出错。有维护的方法吗？我试过捆绑更新。有人有什么想法吗？我已升级到macOS Mojave 10.14.6。谢谢

public class UnoCard {
    enum Color {
        RED, BLUE, GREEN, YELLOW, WILD;

        private static final Color[] colors = Color.values();
        public static Color getColor(int i){
            return Color.colors[i];
        }

        enum Value {
            ZERO, ONE, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, SKIP, DRAW_TWO, REVERSE, WILD, WILD_FOUR;
            private static final Value[] values = Value.values();
            public static Value getValue(int i){
                return Value.values[i];
            }
    }

    private final Color color;
    private final Value value;

    public UnoCard(final Color color, final Value value){
        this.color = color;
        this.value = value;
    }

    public Color getColor(){
        return this.color;
    }

    public Value getValue(){
        return this.value;
    }

    @Override
    public String toString() {
        return color + "_" + value;
    }
}
