ubuntu - PIP 找不到任何满足 SQLAlchemy 要求的下载

Question

• 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。

$ 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

以下所有内容均无效

$ 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。

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？

答:升级pip。

我安装了 1.1 版。使用 sudo pip install --upgrade pip 我得到了版本 8.1.2 和我想要正确安装的包。
