推荐答案
script 标签中的 bundle.js src 是错误的.它正在返回您的主要 index.html，这就是您收到该错误的原因 - JS 解析器正在尝试解析 HTML 文件.
Your bundle.js src in your script tag is wrong. It's returning your main index.html, that's why you are getting that error - the JS parser is trying to parse a HTML file.
您必须在脚本 src 中添加斜杠:<script src="/bundle.js"></script>
You must add a slash to your script src:
<script src="/bundle.js"></script>
如果这不起作用，您必须仔细检查您的 output 配置.
If that doesn't work you must double-check your output config.
