Answer 1

此错误最有可能是因为您位于代理之后，或者您所在的组织中正在使用代理。要查找代理名称和端口，您需要执行以下步骤：
1.开始跑步
2.输入“ inetcpl.cpl”
3.转到连接选项卡
4.进入局域网设置在那里您会找到地址和端口

在以下命令中获得“地址”和“端口”后，将其替换为“ proxy_name”和“ port”，然后将“用户名”替换为“您的用户名”，将“密码”替换为“您的密码”并运行

npm配置集代理http://username:password@proxy_name:port

npm配置设置为http-proxy http://username:password@proxy_name:port

然后运行npm。

这应该可行

npm ERR！代码E407需要代理身份验证
