uniapp打包上传后报错：
TypeError: Cannot read property 'getElementsByTagName' of undefined TypeError: Cannot read property 'getElementsByTagName' of undefined at at (app-service.js:2190:18605) at at (app-service.js:2190:19749) at require (WASubContext.js:2:1907128) at at (app-service.js:2191:10)
错误原因：因为使用了阿里粑粑iconfont，打包的时候把里边iconfont.js一起打包进去了,所以就报错了，把这个删了再打包发布就没问题了。
