uniapp网页运行正常，真机调试报错

真机调试偶尔有几屏发白，一直报下面的错误
解决办法：

1.删除引用的iconfont.js，因为在app中不生效，还会报错
2.在uniapp中安卓使用iconfont的正确教程参考这个
3.这个问题找问题找了半天，真的难找

错误1：20:57:07.896 TypeError: Cannot set property '_iconfont_svg_string_4447983' of undefined

错误2：20:34:35.264 [JS Framework] Failed to execute the callback function:
