微信小程序tabbar怎么设置

pages.json文件夹中pages平级

"tabBar": {
    "list": [
        {
            "pagePath": "pages/home/home",
            "text": "首页",
            "iconPath": "icon",
            "selectedIconPath": "选中"
        },
        {
            "pagePath": "pages/cate/cate",
            "text": "发卡",
            "iconPath": "icon",
            "selectedIconPath": "选中"
        },
    ]
}

最少配置2个tabbar不然报错
