            &.alert {
                .btn {
                    background-color: $btncolor;
                    color: #FFFFFF;
                    font-size: 28rpx;
                    border-radius: 60rpx;
                    height: 66rpx;
                    width: 300rpx;
                    padding: 0 40rpx;
                    display: flex;
                    justify-content: center;
                    align-items: center;
                }
            }

            &.confirm {
                justify-content: space-around;

                .btn {
                    min-width: 230rpx;

                    &.active {
                        background-color: $btncolor;
                        color: #FFFFFF;
                    }

                    &.cancel {
                        border: 1rpx solid $btncolor;
                        color: $btncolor;
                        border-radius: 66rpx;
                    }
                }
            }

        }
    }
}
</style>

在pages.json中插入这个组件路径：

{
            "path": "components/dialog/index",
            "style": {
                "navigationStyle": "custom",
                "app-plus": {
                    "animationType": "fade-in",
                    "background": "transparent",
                    "popGesture": "none"
                }
            }
        }

最后在app.vue中调用：

export default {
    onLaunch() {
        uni['dialog'] = dialog;
    },
    mounted() {
        uni.dialog.alert("消息文本","提示",()=>{
                    uni.showToast({ title: '好的', icon:"none" });
                },"好的");
   }

效果：

最后：我修改了一下dialogUtils.js的语法，把commonJs语法改成了ESM语法。
