root@krusty:/www/site.com# casperjs ./amazon_login.js
Title: Amazon Sign In
PhantomJS has crashed. Please read the bug reporting guide at
<http://phantomjs.org/bug-reporting.html> and file a bug report.
Segmentation fault (core dumped)

我无法弄清楚原因。这里有人知道这个吗？我不知道还有什么要输入，但这就是说我必须在我显示的代码片段中添加更多文字批量，所以这就是我所做的：我＆＃39;我在谷歌搜索了这次崩溃的文本，发现我必须导出一个特定的QT变量，所以我也这样做了，它在执行phantomjs时稍微进行了一些脚本功能，但仍然崩溃。

如果我是专门从幻影＆＃39;幻影＆＃39;并取消注释下面写的脚本代码的前几行我得到这个输出：

root@krusty:/www/nuper.com# /root/phantomjs-2.1.1-linux-x86_64/bin/phantomjs ./amazon_login.js

phantomjs访问的amazon_login.js中的代码：

//phantom.casperPath = '/root/node_modules/casperjs';
//phantom.injectJs('/root/node_modules/casperjs/bin/bootstrap.js');

// if you need the test environment then you need this
//phantom.casperTest = true;

var casper = require('casper').create();

Answer 1

您在最后一行中有.done方法，并且您在Casper对象而不是测试对象上调用它。完成方法是Casper中Tester模块的方法，你在没有Tester模块的情况下调用你的casper。

根据您在第一种情况下的代码中断，我建议您倾听所有错误事件，例如page.error，resource.error ......

希望有所帮助！

为什么casperjs（phantomjs引擎 - Ubuntu x86_64 16.04）在命令行崩溃？
