Python pip install(使用代理)无法解析VPN后面的VM中的服务器

Question

我的设置:

• 企业网络上的Windows 7 64位主机
• Ubuntu 12.04 64位VirtualBox客户端
  • Ubuntu guest配置了VirtualBox Bridged适配器
  • 代理设置确认有效:Firefox可以访问企业内部网站点以及互联网,apt-get install也可以

以下是我到目前为止配置代理所做的工作:

/etc/profile.d/proxy.sh:

export http_proxy="http://<my_proxy>:<my_port>"
export https_proxy="http://<my_proxy>:<my_port>"
export ftp_proxy="http://<my_proxy>:<my_port>"

为了获得工作能力,修改了/etc/apt/apt.conf.d/01proxy:

Acquire::http::Proxy “http://<my_proxy>:<my_port>"

要在使用sudo时保持env变量,修改/etc/sudoers.d/proxy:

Defaults env_keep += "http_proxy https_proxy ftp_proxy"

我还在设置 - >网络 - >网络代理中设置了HTTP/HTTPS/FTP代理设置,然后单击"应用系统范围".

问题是,当我尝试pip install(有或没有sudo)时,它失败并出现错误:

$ pip -vv install git-review

我尝试使用--proxy选项(--proxy=http://<my_proxy>:<my_port>带/不带=符号,带/不带引号),但即便如此也显示相同的错误.

我也尝试过如下设置.pip/pip.conf:

[global]
timeout = 60
proxy = http://<my_proxy>:<my_port>

作为另一个数据点,如果它有帮助,nslookup从命令行失败的企业内部网外的域,但适用于其中的域.然而,如前所述,Firefox和apt-get似乎没有使用代理解析域名的问题.

有任何想法吗？谢谢!

这是由 pip 中的一个错误引起的，该错误已于 2014 年 6 月解决
