Vue 和 Vue-template-compiler version > "2.1.4" 在浏览器中给出错误

Question

一切都很好，很漂亮。然后我将 Vue 和 Vue-template-compiler npm 包升级到 2.1.4 以上的版本，然后我的浏览器中没有任何显示，除了以下错误：

(unknown) [Vue warn]: Error when rendering root instance: warn

返回到版本 2.1.4，一切又好了...我怎样才能成功更新 Vue 和 Vue-template-compiler？

Answer 1

这似乎是同一个问题，已被提出 here。您应该将 vue-template-compiler 升级到 2.2.0，这样应该可以解决问题。

Answer 2

vue中的一个方法重命名了： https://github.com/vuejs/vue/commit/4b51ad048306367a6fb6fbee7445e086d855f31e

您的代码或依赖项可能仍使用 _h。就我而言，它与 Quasar 框架有关。使用 vue-template-compiler 2.1.6 更新到 Quasar Framework 10.3 和 vue 2.1.6 后，问题解决了。看： https://github.com/quasarframework/app-template-default/issues/5

浏览 github 在 _h 上搜索，vue 把我带到了那里。
