vue3 中有个bug this.$waterfall.forceUpdate()

[yukaige]

会报错
Uncaught TypeError: Cannot read properties of undefined (reading 'forceUpdate')
需要将index.js中的

        app.$waterfall = {
            forceUpdate: function forceUpdate() {
                bus.emit('forceUpdate');
            },
            mix: function mix() {
                bus.emit('mix');
            }
        };

改为

        app.config.globalProperties.$waterfall = {
            forceUpdate() {
                bus.emit('forceUpdate');
            },
            mix() {
                bus.emit('mix');
            }
        };
