问题解决了，是我本地的Whistle rules写错了，应该是rule匹配却因为少了一个
/，Whistle默认转成了host匹配，所以文件找不到。 本地打包好的js文件放在127.0.0.1:8080/目录下，即通过127.0.0.1:8080/*.js能加载成功，如果通过路径为127.0.0.1:8080/gjj/*.js就找不到，找不到时默认返回index.html文件，html文件以js格式解析所以报SyntaxError: Unexpected token ‘<’，因为html文件是以<!DOCTYPE html>开头；配置问题解析： rules配置：
**.cmfurl.cn/gjj/ 127.0.0.1:8080(错误) 改成： rules配置：**.cmfurl.cn/gjj/ 127.0.0.1:8080/（正确） 即可。错误的rules配置，相当于请求
**.cmfurl.cn/gjj/中的js文件时代理到127.0.0.1:8080/gjj中查找相应的js文件。这是host匹配，127.0.0.1:8080匹配**.cmfurl.cn正确的rules配置，相当于请求
**.cmfurl.cn/gjj/中的js文件时代理到127.0.0.1:8080/中查找相应的js文件。这是rule匹配，127.0.0.1:8080/匹配**.cmfurl.cn/gjj/host 和 URL 替换的区别参考下这篇文章：https://juejin.im/post/5e14445be51d45415a66754a
