无法使用Pip安装任何软件包 [英] Unable to install any package using Pip

问题描述

每当我运行命令pip install Django时，我都会得到以下错误跟踪，这意味着存在一些版本冲突.我尝试先卸载再安装相同的程序包，但是它抛出了相同的错误.

Whenever I run the command pip install Django I get the following error trace which means there is some version conflict. I tried uninstalling and then installing the same package, but it's throwing up the same error.

Cleaning up...

我正在使用Python 2.7.有人知道这是什么问题吗?

推荐答案

似乎所有问题都是由于certifi版本冲突

It seems like all the problem is because of certifi version conflict

所以请尝试从此处下载源代码 https://pypi.python.org/pypi/certifi

so try downloading the source from here https://pypi.python.org/pypi/certifi

并从源代码安装

将其提取到文件夹中并运行此命令

Extract it go into the folder and run this command

sudo python setup.py  install

它应该可以工作
