我是Windows用户，安装了yarn、node-js、git、npm。在我用命令npx创建react应用程序时，我的应用程序开始创建，但几乎在最后我标记了这个错误：
PS C:React> npx create-react-app my-app

Removing .git directory...
Success! Created my-app at C:Reactmy-app
Inside that directory, you can run several commands:
yarn start
Starts the development server.
yarn build
Bundles the app into static files for production.
yarn test
Starts the test runner.
yarn eject
Removes this tool and copies build dependencies, configuration files
and scripts into the app directory. If you do this, you can’t go back!
We suggest that you begin by typing:
cd my-app
yarn start
Happy hacking!

我该怎么解决？
使用配置您的git标识
git config --global user.name <yourName>
git config --global user.email <yourEmail>
例如，您可以使用您的GitHub帐户数据。
