需要从失败中成长
1)重新安装npm 其实就是重新安装node
2）删除.npm的这个目录，重新搞一次
3）删除/usr/local/lib/node_module/
重新进行创建项目，原生态的npm，不用淘宝的地址

Initialized a git repository.
Success! Created my-app at /Users/apple/learn/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!
