无法找出问题所在。非常感谢您的帮助。

Answer 1

您有网络连接问题

npm ERR! network getaddrinfo ENOTFOUND registry.npmjs.org registry.npmjs.org:443

1. 确保您已连接到互联网
2. 如果您位于代理后面，则“代理”配置已正确设置。请参阅：npm help config

Answer 2

好像您遇到连接问题。

尝试使用ping工具检查您的连接以检查您的连接：

ping google.com

您的问题可能有很多：代理，电缆断开，dns。在Ubuntu上也可能是一个问题，要解决它值得尝试重新启动网络管理器]

sudo service network-manager restart
