在Windows上安装Python 2.7.8的pip

Question

我想要安装Python 2.7.8下的pip模块，这是arcGIS为你安装的版本。

我正在使用引导方法安装pip，但在运行命令提示符中的get-pip.py时遇到了错误。

我得到了以下错误信息：

我正在使用公司提供的网络。您认为防火墙是导致出现错误的原因吗？

你为什么使用2.7版本？有特定的目的吗？你可以使用3.0版本，它默认安装了pip，所以不会有任何问题。 - whatsinthename

我的Python是由ArcGIS软件安装的。Python 2.7.8是唯一与该软件兼容的版本。我不知道。 - Vincent Law

Answer 1

由于你在防火墙内部并且从防火墙外部安装文件，因此你需要设置代理。

Ubuntu：

export http_proxy="http://<<username>>:<<password>>@<<proxy server>>:<<proxy_port>>"
export https_proxy="https://<<username>>:<<password>>@<<proxy server>>:<<proxy_port>>"

Windows:

set HTTP_PROXY=http://<<username>>:<<password>>@<<proxy server>>:<<proxy_port>>
set HTTPS_PROXY=https://<<username>>:<<password>>@<<proxy server>>:<<proxy_port>>

当我运行命令时，我需要更改用户名、密码和代理端口吗？ - Vincent Law

@VincentLaw 是的，这通常是 < > 的意思。 - Code-Apprentice

Answer 2

我认为你应该先下载get-pip.py，然后运行python get-pip.py。

如果这不起作用，请使用python get-pip.py --prefix=/usr/local/。

希望这能帮到你。
