Answer 1

此错误很可能是因为您使用了代理，或者您在使用代理的组织中。要找到代理名称和端口，您需要执行以下步骤：
1.go 到运行
2.type"inetcpl.cpl"
3.Go 到“连接”选项卡
4.进入局域网设置在那里你会找到地址和端口

获得 "address" 和 "port" 后，在下面的命令中将其替换为 "proxy_name" 和 "port"，并将 "username" 替换为 "your username" 和 "password" 以及 "your password" 和运行

npm config set proxy http://username:password@proxy_name:port

npm config set http-proxy http://username:password@proxy_name:port

之后运行 npm.

这应该可行

编辑：在运行ning npm config 之前，URL 应该被编码，这可以通过将 URL 复制粘贴到这个网站 https://www.urlencoder.io/
