PIP 找不到任何满足 SQLAlchemy 要求的下载 [英] PIP Could not find any downloads that satisfy the requirement SQLAlchemy

问题描述

• Ubuntu 12.04
• Apache 2.2.22

pip 已停止在我的 ubuntu 服务器上工作，并在我尝试下载任何内容时出现以下错误.

pip has stopped working on my ubuntu server and gives the below error when I try to download anything.

$ sudo pip install SQLAlchemy
Downloading/unpacking SQLAlchemy
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement SQLAlchemy
No distributions at all found for SQLAlchemy
Storing complete log in /home/user/.pip/pip.log

以下所有方法都不起作用

All of the below also do not work

$ sudo pip install --upgrade pip 
$ sudo apt-get install build-essential

我的 /etc/environment 具有以下以前有效的设置.

My /etc/environment has the below settings which were working previously.

http_proxy="http://myproxyhere:portnumberhere/"
HTTP_PROXY="http://myproxyhere:portnumberhere/"

我的/home/user/.pip

有没有人知道可能出了什么问题?

Has anyone got any idea what might be going wrong?

推荐答案

您需要通过 HTTPS 而不是 HTTP 获取 pypi.

You need to fetch pypi over HTTPS, not HTTP.

出于某种原因，您的 pip 配置为从 http://pypi.python.org/simple/ 而不是 https://pypi.python.org/simple/

For some reason your pip is configured to retrieve from http://pypi.python.org/simple/ rather than https://pypi.python.org/simple/
