npm install -g create-react-app
create-react-app my-app

11、依次执行如下命令：验证：验证缓存文件夹的内容，垃圾收集任何不需要的数据，并验证缓存索引和所有缓存数据的完整性。如图10
npm cache verify
create-react-app my-app

Success! Created my-app at E:\wwwroot\my-app
Inside that directory, you can run several commands:
 
  npm start
    Starts the development server.
 
  npm run build
    Bundles the app into static files for production.
 
  npm test
    Starts the test runner.
 
  npm run 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
  npm start
 
Happy hacking!

12、依次执行如下命令：现在可以在浏览器中查看我的应用程序，如图11
cd my-app
npm start
