我的nodejs服务器呈现空白页面而不是我的react应用程序。
在检查器中，我可以看到它显示了我的index.html，但控制台中存在此错误
'Uncaught SyntaxError: Unexpected token <' main.12045785.chunck.js
我想这是在编译过程中出现的问题，因为当我在VSC中打开此文件main.12045785.chunck.js时，所有文本均为灰色，但是当我从另一个react项目中打开一个chunck文件时，它具有javascript语法颜色。

我不知道问题是否是因为我正在使用.jsx文件，但是我确定我的webpack配置正确地对它们进行了转储。
有什么想法吗？
答案 0 :(得分：0)
将<base href="/" />添加到我的<head>的{{1}}中
，或者如果这样不起作用，请尝试
在脚本src中添加斜杠：index.html
