问题产生的可能原因以及对应的解决方法：
版本不支持：降低版本
权限不够：
方法一：删除C:\Users{账户}\下的npmrc文件 [未找到]
方法二：使用npm cache clean --force命令清理缓存 [无效]
方法三：使用npm install --save --legacy-peer-deps @material-ui/core命令 [未尝试]
方法四：npm install --legacy-peer-deps [未解决，出现其他错误]
可尝试：删除全局包：npm uninstall -g react，再执行npm install [未尝试]
可尝试：使用yarn来安装 [完美解决]
