我基本上基于节点的thin模块上的一个项目，跑的HTTP/HTTPS MITM代理上127.0.0.1:5002
阅读关于这个问题的一些答案，我试图通过使用以删除代理服务器设置：
npm config rm proxy
npm config rm https-proxy
为以及
npm config set proxy = null
所以当我NPM配置ls -l命令它表明这两个设置为空。但是，它仍然拒绝安装。我甚至试图删除我的系统网络代理设置。
任何人都可以帮助解决这个问题吗？我在Virtualbox上运行Ubuntu 16.04上的节点v4.4.7和npm版本2.15.8。谢谢。
也许是在一个仍然可用环境变量？ '$ HTTP_PROXY'或$ $ http_proxy'很常见。 – robertklep
我试着检查我的环境变量，这些变量出现在列表中：'http_proxy = http：//127.0.0.1：5002 /' 'https_proxy = http：//127.0.0.1：5002 /' 'HTTPS_PROXY = http： //127.0.0.1：5002 /' 'HTTP_PROXY = http：//127.0.0.1：5002 /' 我可以将这些设置为空吗？ – QPTR
