query-string最新版本无法用webpack构建项目

query-string这个库用于解析和组装react-router中携带的参数

问题原因：It's the inverse, actually. It's Create React App that doesn't support the ecosystem. Use npm install query-string@5 if you use CRA. Sorry for the trouble, but this is all on CRA which has refused to co-operate with the community and just tells users to annoy maintainers.

解决方案：降级至5.x版本
