听起来好像连接速度很慢.尝试将超时从30秒增加到60秒，方法是将超时添加到您的 .npmrc 文件中:

Sounds like you have a slow connection. Try increasing the timeout from 30s to 60s by adding this to your .npmrc file:

timeout=60000

• 对于Windows: C:\ Users \ {username} \.npmrc
• 对于Mac/Linux 〜/.npmrc

或者您可以在与项目的 package.json 文件相同的目录中创建一个文件.

Or you can create one in the same directory as your project's package.json file.
