前置操作全部执行，运行npm run dev的时候：
ERROR Failed to compile with 59 errors 14:14:06

These dependencies were not found:

qs in ./src/utils/httpRequest.js
vue-hot-reload-api in ./src/App.vue, ./node_modules/.store/vue-loader@13.3.0/node_modules/vue-loader/lib/template-compiler?{"id":"data-v-34f846d8","hasScoped":false,"transformToRequire":{"video":["src","poster"],"source":"src","img":"src","image":"xlink:href"},"buble":{"transforms":{}}}!./node_modules/.store/vue-loader@13.3.0/node_modules/vue-loader/lib/selector.js?type=template&index=0&bustCache!./src/App.vue and 56 others
To install them, you can run: npm install --save qs vue-hot-reload-api

前端启动出现以上报错：
我现在的处理过程，之前cnpm版本高，手动降级到7.1.0版本，其次，nodejs版本也做了降级也就是12.1.0，根据项目报错执行了npm install --save qs vue-hot-reload-api(我用的cnpm)，还是不行。
请问有大佬遇到过吗？帮忙解答一下，谢谢
