系统:android5.0.2
错误:Uncaught TypeError: Cannot define property:ob, object is not extensible
工具:babel5+webpack1.12(babel6依旧有此问题)
版本:vue@1.0.10+vue-router@0.7.7

在点击有路由跳转事件的元素时路由不跳转并出现如下错误(v-link和router.go都会出错)：

刷新之后路由跳转到之前未跳转的路由
目前这个错误只在android5.0上会出现，android5.1,android4.x,ios无此问题

换回vue@0.12.16+vue-router@0.6.0后正常,应该vue1.0的问题

我手头没有 5.0 的机器，你看下在这一行 https://github.com/vuejs/vue/blob/dev/src/observer/index.js#L160
Object.isFrozen(value) 的值是什么？

你看下把那一行的 Object.isFrozen 改成 Object.isExtensible 是否还抛错。

Object.isFrozen(value)的值一直都是都是false
Object.isFrozen(value)改成Object.isExtensible(value)之后进入页面直接报Uncaught TypeError: Cannot define property:__ob__, object is not extensible.，包括anroid4.x和ios也报错。。。
另外Object.isExtensible(value)的值也是false

是我没说清楚，是把 !Object.isFrozen 改成 Object.isExtensible，改的时候要去掉前面那个取反

!Object.isFrozen 改成 Object.isExtensible之后没有报错了，非常感谢

@yyx990803
use isExtensible instead of isFrozen for a safer check (fix #1995)

我用 vue@1.0.10 时正好也遇到了这个问题，不过只是在安卓上的几乎所有的 QQ 浏览器上才会出现。

更新 vue 版本号后就正常了。
