一切都很好，花花公子。然后我将Vue和Vue-template-compiler npm软件包升级到2.1.4以上的版本，然后在我的浏览器中没有显示，除非出现以下错误：

返回版本2.1.4并且一切都很好......我怎样才能成功更新Vue和Vue-template-compiler？

在vue中重命名了一个方法： https://github.com/vuejs/vue/commit/4b51ad048306367a6fb6fbee7445e086d855f31e
您的代码或依赖关系可能仍然使用_h。就我而言，它与Quasar框架有关。用vue-template-compiler 2.1.6更新到Quasar Framework 10.3和vue 2.1.6后，它就解决了。看到： https://github.com/quasarframework/app-template-default/issues/5
浏览github搜索_h和vue将我带到那里。

这似乎是同一个问题，正如here所提出的那样。您应该将vue-template-compiler升级到2.2.0，这应该修复它。
