无法通过pip安装任何软件包 [英] Unable to install any package through pip

问题描述

由于某些原因，我在用pip安装新软件包时遇到问题.我有一个OS Sierra环境，以前一切正常.现在，无论我是否使用virtualenv，我都会得到:

For some reason I have issues installing new packages with my pip. I have an OS Sierra environment and everything was working fine before. Now either I use a virtualenv or not, I get:

Collecting requests
Could not find a version that satisfies the requirement requests (from 
  versions: )
No matching distribution found for requests

这不仅适用于请求"库，还适用于所有其他库(例如django等).

This is not only for the "requests" library but also for all the others (e.g. django etc.).

我有最新的点子

 pip --version
 returns: pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)

我的python版本是:2.7.12

And my python version is: 2.7.12

此外，基于

Moreover based on this article I checked if I can curl the PyPi website and I do get a response back.

有什么想法吗?

pip install -vvv requests

推荐答案

感谢@Klaus D.注释(建议在命令中添加-v标志)，我发现以下URL:

Thanks to @Klaus D. comment (proposed to add: the -v flag in the command), I found out that the URL for:

  http://pypi.python.org/simple/requests/ 

需要更改为

  https://pypi.python.org/simple/requests/  (with SSL).

执行此命令可以正常工作:

Executing this command worked fine:

pip install -v requests -i https://pypi.python.org/simple/

或者，您也可以按照答案之一在此处中所述更改pip.conf文件:

Alternatively you can change the pip.conf file as described in one of the answers here:

[global]
timeout = 60
index-url = https://pypi.python.org/simple
