错误信息：There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.
项目依赖关系树可能有问题。
这可能不是Create React应用中的bug，而是需要在本地修复的问题。
解决方案一：
直接在工程文件夹中新建一个 .env 目标文件，之后把 SKIP_PREFLIGHT_CHECK=true 这句话粘贴到 .env 文件中，这样就可以解决这个错误
注意：这个 .env 文件夹要和src文件夹是平级，否则不生效。
解决方案二：
这个解决方案是我从网上找到的：原地址
这个方法就比较简单，直接在终端输入命令 npm run eject 就可以了
等这行代码跑完之后 npm start 就可以跑起来项目了。

React踩坑系列——脚手架运行npm start时报错
基础知识是前端一面必问的，如果你在基础知识这一块翻车了，就算你框架玩的再6，webpack、git、node学习的再好也无济于事，因为对方就不会再给你展示的机会，千万不要因为基础错过了自己心怡的公司。前端的基础知识杂且多，并不是理解就ok了，有些是真的要去记。当然了我们是牛x的前端工程师，每天像背英语单词一样去背知识点就没必要了，只要平时工作中多注意总结，面试前端刷下题目就可以了。什么？你问面试题资料在哪里，这不是就在你眼前吗（滑稽且多，并不是理解就ok了，有些是真的要去记。
