运行此命令：
virtualenv -p / usr / bin / python3 virtual

显示
OSError：隧道连接失败：需要407代理验证
但我已经配置了代理设置，并且它工作正常。 为什么会这样。
答案 0 :(得分：1)
我发现错误，https_proxy和http_proxy变量未在/ etc / environment文件中设置。
导出http_proxy =＆＃39; http://myusr:mypswd@myproxyname.mydomain.com:8080＆＃39;
导出https_proxy =＆＃39; https://myusr:mypswd@myproxyname.mydomain.com:8080＆＃39;
完成了这项工作。
