Question

这时我要做的就是让项目运行。

我运行tns run android

该应用程序已构建，但在启动该应用程序时抛出错误

ReferenceError：未定义HTMLElement

因此，当我尝试引入新的nativescript主题核心（2.2.0）时，一切就开始了。我遵循了他们在多个地方发布的指南。一切看起来都不错。然后，我运行tns run android，并第一次出现 HTMLElement未定义 错误。

我已经炸掉了node_modules和platform文件夹
npm重建
tns安装
我已卸载nativescript-cli并清除了npm缓存并重新安装（如此处所述：https://discourse.nativescript.org/t/enoent-no-such-file-or-directory-project-pbxproj/7336）

然后我决定再次开始，着手进行一个干净的项目。请按照此处的步骤操作：https://nativescript-vue.org/en/docs/getting-started/quick-start/

当我运行tns run android时，即使我根本没有修改模板，仍然会遇到相同的 HTMLElement未定义 错误。< / p>

我不知道这是一个错误还是我做错了什么

tns-版本6.1.2

节点-v 12.10.0

npm -v 6.10.3

所以无论现在我做什么我都会收到此错误...

明智的代码，例如我说过的，该模板存储库为https://github.com/nativescript-vue/vue-cli-template

这是堆栈。

Answer 1

我找到了解决方案，更新了您的main.js文件

import store from './store' // <= this should be before VueDevtools 
import VueDevtools from 'nativescript-vue-devtools';

Answer 2

@sidheart指出的解决方案有效，但是它不会让您观察商店。触发错误是因为NativeScript没有DOM，因此没有HTMLElement的类型。临时解决方案是将以下行添加到文件new webpack.DefinePlugin({})中webpack.config.js定义的对象中：

HTMLElement: function() {
 return false;
},

使整个对象看起来像这样：

new webpack.DefinePlugin({
  'global.TNS_WEBPACK': 'true',
  TNS_ENV: JSON.stringify(mode),
  process: 'global.process',
  HTMLElement: function() {
    return false;
  },
}),

感谢Brandon Gohsman在his article中展示了此解决方案。

Answer 3

使用以下项目创建项目时

：

vue init nativescript-vue/vue-cli-template <project-name>

不安装vue-devtools。我认为这与尝试访问Nativescript中不存在的DOM的vue-devtools有关。

HTMLElement未定义-Nativescript-vue
