使用create-react-app命令創建一個react項目，運行npm run eject生成配置文件，報了下面的錯：
Remove untracked files, stash or commit any changes, and try again.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] eject: `react-scripts eject`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] eject script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm ERR! A complete log of this run can be found in:

主要問題是腳手架添加.gitgnore文件，但是卻沒有本地倉庫，按照以下順序就可以正常使用
create-react-app test
cd test
git init
git add .
git commit -m 'Saving before ejecting'
npm run eject
