我已经咬了一下子弹，并使用vue-cli和Webpack切换到我的Vue.js的模块化方法。将我的应用程序重组为单个文件组件有一点学习曲线，但我基本上已经到了那里。不过，我现在遇到了一个非常令人费解的问题。我有一个相当复杂的组件ProductDetail，它使用了一些子组件。一旦我添加其中一个，称为TabPage（通过包含导入行并将其添加到components属性），编译就会挂起（如果我重新启动＆＃39; npm run dev＆＃39;它同样会在启动时挂起，之前到达服务页面的地步）。其他6个组件根本不会引起这个问题。
现在奇怪的是，这个组件TabPage可以有效地为空，只不过是输出空div的模板，问题仍然存在，因此它不会成为这个组件的问题（在我切换到使用vue-cli之前，一切都在应用程序的版本中工作。并且它只是这个组件，没有其他因素导致这个问题。
那么是否有一些调试编译过程的方法，以便我可以准确地看到问题发生的位置？
对于它的价值，这里是ProductDetail组件（移除了方法，将其全部缩小到StackOverflow的大小）：

这里是完全削减的TabPage组件，它包含在上面的组件中会导致编译挂起：
<script>
export default{
name:"tab-page",
template:`<div>EMPTY</div>`
}
</script
我已升级到最新节点（v6.9.4 LTS）但这没有帮助。
答案 0 :(得分：0)
值得庆幸的是，这个问题并没有出现任何令人费解的晦涩难懂，而是我没有正确关闭脚本标签的简单事实。我觉得很傻，但也松了一口气。感谢Roy J指出这一点。
