使用create-react-app時的something is already running on port 3000
問題：
本身今天在使用create-react-app搭建react應用的時候，開啓了兩個React app，而後npm start的時候，出現something is already running on port 3000react
解決方法
本身以前也遇到過這個問題，可是沒有記錄下來，我本身試着想，先是npm start port=3001,結果仍是不對。
正確的打開方式應該是PORT=3001 npm start(這個端口只要不和3000相同就行) .npm
總結一下，以避免本身之後好查閱。也分享給遇到這個問題的小夥伴喲app
