Question

我刚刚使用Ember版本9将版本11和CLI从0.1.15移动到0.2.2的Ember-CLI项目。虽然我现在有一个应用程序开始提供文件，然后立即与Segmentation fault: 11崩溃，所以在这里和那里做了所有必要的调整。据我所知，任何地方都没有日志，我对如何调试实际导致故障的方法感到茫然。

非常感谢任何帮助。

了解segfault的一个好方法是在github上安装ddobson的调试工具：https://github.com/ddopson/node-segfault-handler。

您可以使用 npm 安装：

npm install segfault-handler

然后只需将以下两行添加到server/index.js文件中：

var segfaultHandler = require('segfault-handler');
segfaultHandler.registerHandler();

这将为您的node_modules生成堆栈跟踪，这些跟踪正在浸入本机代码中（这可能是您获取 segfault 的原因）。

就我的情况而言，问题显然源于SASS编译：
