bug描述:

以前打包编译都没问题。现在升级以后就出现这个问题。不云打包本地编译调试运行都是好的。只要云打包编译时就报:TypeError: Cannot read property 'length' of undefined 而且是多个文件报这个错误。连app.vue文件中连length都没有也报错。现截图了login.vue文件的报错行和length的地方。这应该是误报吧? 我的password是一个字符串变量。这是可以length的呀。运行的时候都没问题。云打包编译就出问题。希望你们能解决一下。

很奇怪,为什么报 length 未定义呢?以前版本编译都没有这样的错误。而且在本地调试运行都没问题。云打包的时候才出这个问题。跟V3编译有关系吗?

报错的页面如比login.vue这个页。使用length的地方肯定都是合法的。都是字符串变量 比如 password.length .这完全合法,也不存在null的问题,要不本地编译也不会通过。就是这个云打包前的编译会有问题。

我在使用HBuilderX 2.8.3进行离线打包的时候也遇到了这个问题

    我们的问题原因找到了

    background: linear-gradient(to bottm);

    这个bottom单词写错了,然后就报错,但是报错的地方不对,也没有发现其他异常
