我正在将我的Vue应用程序发布到生产环境中,但是一个特定组件会抛出一条我无法跟踪的深奥错误消息,因为所有项目文件都已捆绑在一起并且变量名称已更改。此错误也只能在生产模式(构建)中重现,这使我相信这是与捆绑本身相关的问题。
重现步骤
正如我之前提到的,问题仅存在于生产模式中。因此,我已经尽力通过简单地在Netlify上发布应用程序来重现该问题。以下是步骤:
这样做会带你到错误的路线/组件(grandquest.netlify.com/map)

webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

这两个细节让我相信这个问题是由捆绑错误引起的
-
我试过在我的代码中寻找任何变量名称e
,想想也许这是一个事件,但我的代码中没有这样的变量。它似乎是一个由vue“捆绑”的变量。
由于此错误的性质(我不确定变量e
在代码中是什么,因为它被混淆了),我已尽力总结Map组件的相关代码。我也不介意共享整个文件,如果它可以帮助,但是,没有找到e
变量。

预期产出
您应该在资产加载时看到加载屏幕一段时间,然后屏幕上会出现一个地图。您可以使用光标上下导航此地图,也可以单击各个商店。
实际输出
屏幕似乎无限期加载,因为发生了已停止应用程序的错误。该错误现在应该出现在控制台中,读取类型错误:e未定义(在Firefox上)
任何和所有的帮助都受到这个问题的赞赏:)
这个功能存在吗?
v-on:resize="resizeMonitor"
我没有在任何地方看到它。我想如果函数不存在,你会得到这种类型的错误
