错误：找不到与pip匹配的发行版

Question

我正在尝试在我的Python 2.6.6中安装pip，我使用的是Oracle Linux 6

我按照此链接给出的答案进行操作Link

我下载了 get-pip.py 文件并运行了以下命令

sudo python2.6 get-pip.py

然而我得到以下错误

[root@bigdatadev3 Downloads]# sudo python2.6 get-pip.py

错误显示出现了一些网络问题，但我在这里拥有完全开放的互联网访问。

我该如何安装pip？

我还尝试了yum，yum install python-pip 但是它给出了以下信息

[root@bigdatadev3 ~]# yum install python-pip
Loaded plugins: refresh-packagekit, security, ulninfo
Setting up Install Process
No package python-pip available.
Error: Nothing to do

更新1：

我使用了以下命令：

python get-pip.py --proxy="MY_PROXY"

我遇到了以下错误

可能会出现以下警告信息：DEPRECATION: Python 2.6 已不再得到 Python 核心团队的支持，请升级您的 Python。未来版本的 pip 将停止支持 Python 2.6。正在收集 pip... - iFlo

我无法升级我的Python，我只能忍受它。 :( - Hardik Gupta

你正在使用代理吗？sudo 不会继承你当前的代理参数。如果是这样，请尝试以下方法：python get-pip.py --proxy="[user:passwd@]proxy.server:port" - iFlo

我之前使用sudo命令这样导出了我的代理：export http_proxy=<MY_PROXY>， export https_proxy=<MY_PROXY>。 - Hardik Gupta

这就是为什么它不起作用，使用sudo将不会使用那些导出。 - iFlo

我应该使用什么？yum安装出现了相同的问题。 - Hardik Gupta

Answer 1

由于使用sudo，这是一个代理问题。使用sudo启动命令并不能确保像export http_proxy=<MY_PROXY>这样的导出内容仍然是最新的。

你可以尝试以下解决方法：

python get-pip.py --proxy="[user:passwd@]proxy.server:port"

如果您没有用户名/密码，只需：

python get-pip.py --proxy="proxy.server:port"

例子：

python get-pip.py --proxy="192.168.0.12:3128"

我需要在双引号中提供代理吗？ - Hardik Gupta

你应该看这里：https://dev59.com/CVkT5IYBdhLWcg3wStzQ - iFlo

Answer 2

首先在Windows中以管理员身份运行命令提示符。然后尝试使用以下命令：python get-pip.py --trusted-host=files.pythonhosted.org --trusted-host=pypi.org。我已经尝试过并且对我有效。

为什么你认为他们在运行Windows，当他们明确说明了是Oracle Linux？ - RaidPinata

Answer 3

我更新了我的~/.pip/pip.conf文件，如下所示：

index-url = https://
trusted-host={my-artifactory-url}
