2、错误原因

      create-react-app不是内部命令，但是可以使用npx命令进行安装，npx create-react-app

3、解决办法

Administrator@SKY-20160824VTF MINGW64 /d/HBuilderProjects/cmn
$ cnpm install create-react-app

Administrator@SKY-20160824VTF MINGW64 /d/HBuilderProjects/cmn
$ create-react-app cmn
bash: create-react-app: command not found

Administrator@SKY-20160824VTF MINGW64 /d/HBuilderProjects/cmn

Initialized a git repository.

Success! Created cmn at D:HBuilderProjectscmncmn
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 cmn
  yarn start

Happy hacking!
