It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.
Windows:
set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py
Linux/OS X:
export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py
However if this still doesn’t work for you, you can always install pip through a proxy using setuptools’ easy_install by setting the same environment variables.
Windows:
set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip
Linux/OS X:
export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip
Then once it’s installed, use:
pip install --proxy="user:password@server:port" packagename
From the pip man page:
–proxy
Have pip use a proxy server to access sites. This can be specified
using “user:password@proxy.server:port” notation. If the password
is left out, pip will ask for it.
