回答: 这个报错的原因可能有几种情况。首先,根据引用\[1\]的报错信息,可能是在app.js文件的第160行出现了一个未定义的属性。具体来说,是在一个undefined对象上尝试读取'prototype'属性,导致报错。这可能是由于代码中的某个对象没有正确初始化或者赋值导致的。其次,根据引用\[2\]的情况二,如果在异步请求获取数据时,数据属性还未定义,尝试读取该属性也会导致类似的报错。在这种情况下,可以通过在初始化时给属性赋一个空对象来解决。最后,根据引用\[3\]的内容,如果在引入element时没有正确修改main.js文件,也可能导致类似的报错。确保正确引入element并修改main.js文件可以解决这个问题。
