无法通过pip安装任何软件包
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:
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)。
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)
而我的python版本是:2.7.12
此外,根据本文,我检查了是否可以卷曲PyPi网站,并且确实得到了回复。
知道有什么问题吗?
已编辑
我以如下方式执行pip安装:
pip install -vvv requests
我得到了错误的详细输出:

感谢@Klaus D.注释(建议在命令中添加-v标志),我发现以下URL:
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:
pip install -v requests -i https://pypi.python.org/simple/
或者作为答案的一个描述你可以改变pip.conf文件在这里:
[global] timeout = 60 index-url = https://pypi.python.org/simple
