使用官方推荐的 npx create-react-app QuickGeneratorWeb 创建

$ npx create-react-app QuickGeneratorWeb
Could not create a project called "QuickGeneratorWeb" because of npm naming restrictions:
  *  name can no longer contain capital letters

报错:npm 不再支持大写命名, 改用小写重新创建

$ npx create-react-app quick-generator-web

...

A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported.

报错: 生成的模板项目缺失文件, 原因是 create-react-app 工具需要非全局安装且是最新的, 卸载create-react-app

$ npm uninstall -g create-react-app
removed 63 packages in 2.251s

$ rm -rf quick-generator-web/

重新创建项目

$ npx create-react-app quick-generator-web

Created git commit.

Success! Created quick-generator-web at D:\git\web\quick-generator-web
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 quick-generator-web
  yarn start

Happy hacking!
