结帐后，当我说react-native run-android im低于错误时。

Metro Bundler has encountered an internal error, please check your terminal error output for more details

下面是我项目中的package.json。

有人遇到这个问题并解决了吗？

我是angular.js的新手.我试图通过输入以下代码行在Ubuntu 12.04中安装bower.节点已成功安装在本地计算机上.

sudo npm install -g bower

低于错误

我有一些元素以及每个元素中的上一个和下一个链接.好像我点击下一步我想要只向下一个可见的div添加一个类,我想跳过隐藏的div,如果div被隐藏,则将class添加到隐藏元素后可见的下一个div.因为我写了这样的东西

$('.next').click(function(){
   $('.slide').removeClass('highZindex');
   $(this).closest('.slide').next('.slide:visible').addClass('highZindex')
})

我只是想从所有这些元素中删除添加的类,只需要添加到下一个可见元素但是发生的事情是如果单击下一个链接并且如果下一个div被隐藏它会跳过所有元素并直接转到最后一个div和类也没有添加到任何元素.

$('.slide').first().addClass('highZindex');


$('.prev').click(function(){
$('.slide').removeClass('highZindex');
$(this).closest('.slide').prev('.slide:visible').addClass('highZindex')
})

$('.next').click(function(){
   $('.slide').removeClass('highZindex');
   $(this).closest('.slide').next('.slide:visible').addClass('highZindex')
})

.slide {border:1px solid; height:200px; width:200px;position:absolute;top:0px; left:0px; background-color:#fff; }
.highZindex {z-index:1000}
