Answer 1

此错误很可能是因为您落后于代理，或者您可能在使用代理的组织中。要查找代理名称和您需要执行以下步骤的端口：
1.跑步
2.型" inetcpl.cpl"
3.到达连接选项卡
4.转到LAN设置在那里您会找到地址和端口

在以下命令中获得"地址"one_answers" port"端口后用" proxy_name"one_answers" port"替换为" proxy_name"one_answers" port"，然后用"您的用户名"one_answers"密码"替换为"用户名"，然后运行

npm配置设置代理http：//用户名：password@proxy_name：port

npm配置设置http-proxy http：//用户名：password@proxy_name：port

之后运行npm。

这应该可能起作用
