It looks as though you need the webcomponents-loader.js file. 似乎您需要webcomponents-loader.js文件。 If you did not make this with node.js (you can learn it here ), you will need to find that file yourself, or install node.js. 如果您不是使用node.js实现的（您可以在此处学习），则需要自己找到该文件或安装node.js。
The following instructions will not help you learn how this works. 以下说明不会帮助您了解其工作原理。 I would HIGHLY recommend you watch the video link above to learn about node.js before you follow these instructions. 在按照这些说明进行操作之前，我强烈建议您观看上面的视频链接以了解node.js。
If you have a folder on your computer with the HTML and JS files (and node.js on your computer) you can open a terminal on your computer, navigate to that folder in the terminal (cd folder_name etc...), and run npm init or sudo npm init , whichever works. 如果您的计算机上有一个包含HTML和JS文件的文件夹（以及计算机上的node.js），则可以在计算机上打开一个终端，导航到终端中的该文件夹（cd folder_name等），然后运行npm init或sudo npm init ，以任何sudo npm init方式。
Then to get a hold of that file, you will need to run npm i webcomponents.js to install webcomponents.js . 然后要保留该文件，您将需要运行npm i webcomponents.js来安装webcomponents.js 。 Then if you open the folder with the HTML and JS files in a code editor, you should be able to see a folder called node_modules. 然后，如果在代码编辑器中打开包含HTML和JS文件的文件夹，则应该能够看到名为node_modules的文件夹。
In that folder you can find webcomponentsjs and under that, there is webcomponents-loader.js . 在该文件夹中，您可以找到webcomponentsjs ，在该文件夹下有webcomponents-loader.js 。 You can copy that file and paste it where the main JavaScript file is. 您可以复制该文件并将其粘贴到主JavaScript文件所在的位置。 Then change the script code to <script src="src/webcomponents-loader.js"></script> 然后将脚本代码更改为<script src="src/webcomponents-loader.js"></script>

<script src="node_modules/@webcomponents/webcomponentsjs/webcomponents-loader.js"></script>
This part says that you need to install the node.js & npm and run it. 这部分说您需要安装node.js和npm并运行它。 I recomend you to search what "npm" is. 我建议您搜索“ npm”是什么。
