无法通过代理升级 pip

我已经尝试了另一个问题中的所有建议，但它对我来说不起作用：无法升级 pip

我正在运行 Ubuntu 12.04，并且能够使用 安装 pip 1.0 apt，但该版本显然存在一个不能与代理很好地兼容的错误，所以我不知道如何更新它。

以下是我在控制台中得到的信息：

$ pip --version
pip 1.0 from /usr/lib/python2.7/dist-packages (python 2.7)
$ which pip
/usr/local/bin/pip

尝试 #1

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

尝试 #2

$ python ~/Downloads/get-pip.py --proxy=$http_proxy
/usr/lib/python2.7/dist-packages/setuptools/command/install_scripts.py:3:
UserWarning: Module pip was already imported from 
/tmp/tmpqbetIm/pip.zip/pip/__init__.py, but /usr/lib/python2.7/dist-packages
is being added to sys.path from pkg_resources import Distribution, PathMetadata, ensure_directory

我可以simple/pip直接使用浏览器访问该文件夹：

https://pypi.python.org/simple/pip/

我也没有使用非代理连接的选项。

以下是 ~/.pip/pip.log 的内容：

只需尝试以下

pip install --proxy=user:pass@server:port <package Name>

例如

pip install --proxy=http://10.10.10.150/accelerated_pac_base.pac quandl
