新电脑&＃xff0c;安装一些包&＃xff0c;直接说407
需要代理身份验证-无法通过公司代理

所以npm config rm registry

重新配置&＃xff0c;镜像源&＃xff0c;切换成官网的&＃xff1a;

npm config set registry https://registry.npmjs.org/


然而不解决问题

$ npm config get registry
https://registry.npmjs.org/houhongf&＃64;MINGW64 /c/zoeCode/nfcclienttools (master)
$ npm install

切换回淘宝镜像

npm config set registry https://registry.npm.taobao.org/


install 还是会报错

node.js需要走环境代理&＃xff0c;需要单独配置代理&＃xff1a;
命令行&＃xff1a;
proxy.com 公司代理地址
port : 代理的端口号

npm config set proxy http://proxy.com:port;
npm config set https-proxy http://proxy.com:port;


配置完&＃xff0c;去install&＃xff1a;

$ npm install
npm WARN client-tool&＃64;1.0.0 No description

上述问题&＃xff0c;可以看https://blog.npmjs.org/post/78085451721/npms-self-signed-certificate-is-no-more&＃xff0c;不晓得能否解决问题

看到有人说通过以下命令可以解决

npm config set strict-ssl false


然而&＃xff0c;npm install又报错了

如果公司代理需要登录&＃xff0c;那么需要设置用户名和密码&＃xff0c;命令如下&＃xff1a;
可以参考网址&＃xff1a;https_proxy的格式

username 用户名&＃xff0c;登录电脑的用户名
password 上网密码
proxy.com 公司代理地址
port 端口号

npm config set proxy http://username:password&＃64;proxy.com:port;
npm config set https-proxy http:///username:password&＃64;proxy.com:port;


可以参考状态码意思&＃xff1a;http状态码
参考一些node错&＃xff1a;node报错
