解决方案，把tabBar里面的单位全改为px，rpx是不会显示的！

注意了，改完一定要重新运行，不然无效，坑爹

"tabBar": {"borderStyle": "black","selectedColor": "#2563EB","color": "#94A3B8","height": "64px","fontSize": "12px","iconWidth": "24px","list": [{"pagePath": "pages/index/index","iconPath": "static/images/icon_frame.png","selectedIconPath": "static/images/icon_frame_active.png","text": "首页"}, {"pagePath": "pages/exercise/index","iconPath": "static/images/icon-square-bar.png","selectedIconPath": "static/images/chart-square-bar_active.png","text": "运动"}]}

真无语，px是不能适配的啊，谁有解决方案？
