PIP已经停止在我的Ubuntu服务器上工作，并给出了下面的错误，当我尝试下载任何东西。
$ 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 以下所有也不起作用
$ sudo pip install --upgrade pip $ sudo apt-get install build-essential
我的/etc/environment具有以前工作的以下设置。
http_proxy="http://myproxyhere:portnumberhere/" HTTP_PROXY="http://myproxyhere:portnumberhere/"
我的/home/user/.pip

有没有人有任何想法可能会出错？
您需要通过HTTPS获取pypi，而不是HTTP。
出于某种原因，您的pip被配置为从http://pypi.python.org/simple/检索，而不是https://pypi.python.org/simple/
答：升级点子。
我有版本1.1安装。 随着sudo pip install --upgrade pip我得到了版本8.1.2和我想正确安装的软件包。
您未使用自2013年末以来使用的https连接。
您可以使用–index选项来更正索引url。 见http://pip.readthedocs.org/en/latest/reference/pip_wheel.html#index-url
你可以通过一个特定的索引url -i ：
sudo pip install SQLAlchemy -i https://pypi.python.org/simple
为什么不尝试在超级用户中安装pip？ 键入su和密码，然后尝试sudo pip install SQLAlchemy
pip sudo pip install --upgrade pip -i https://pypi.python.org/simple
那么，你可以使用pip作为：
sudo pip install SQLAlchemy
-i指定索引URL sudo pip install SQLAlchemy -i https://pypi.python.org/simple
虽然这是个老问题，但我的解决方案可能会帮助别人。
pip install SQLAlchemy --extra-index-url=https://pypi.python.org/simple/
这对我有用。
