How to set an HTTP proxy in Python 2.7?
PythonPython Problem Overview
I am trying to run a script that installs pip: get-pip.py and am getting a connection timeout due to my network being behind an HTTP proxy. Is there some way I could configure an HTTP proxy in my Python 2.7 installation to be able to install what I am trying to install?
Note: I am using Windows. Below is the error I am getting:
C:\SetupFiles>python get-pip.py
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
Python Solutions
Solution 1 - Python
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:[email protected]:port" notation. If the password
> is left out, pip will ask for it.
Solution 2 - Python
On my network just setting http_proxy didn't work for me. The following points were relevant.
1 Setting http_proxy for your user wont be preserved when you execute sudo - to preserve it, do:
sudo -E yourcommand
I got my install working by first installing cntlm local proxy. The instructions here is succinct : http://www.leg.uct.ac.za/howtos/use-isa-proxies
Instead of student number, you'd put your domain username
2 To use the cntlm local proxy, exec:
pip install --proxy localhost:3128 pygments
Solution 3 - Python
You can install pip (or any other package) with easy_install almost as described in the first answer. However you will need a HTTPS proxy, too. The full sequence of commands is:
set http_proxy=http://proxy.myproxy.com
set https_proxy=http://proxy.myproxy.com
easy_install pip
You might also want to add a port to the proxy, such as http{s}_proxy=http://proxy.myproxy.com:8080
Solution 4 - Python
You can try downloading the Windows binaries for pip from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pip.
For using pip to download other modules, see @Ben Burn's answer.
Solution 5 - Python
For installing pip with get-pip.py behind a proxy I went with the steps below. My server was even behind a jump server.
From the jump server:
ssh -R 18080:proxy-server:8080 my-python-server
On the "python-server"
export https_proxy=https://localhost:18080 ; export http_proxy=http://localhost:18080 ; export ftp_proxy=$http_proxy
python get-pip.py
Success.
Solution 6 - Python
cd C:\Python34\Scripts
set HTTP_PROXY= DOMAIN\User_Name:Passw0rd123@PROXY_SERVER_NAME_OR_IP:PORT#
set HTTP_PROXY= DOMAIN\User_Name:Passw0rd123@PROXY_SERVER_NAME_OR_IP:PORT#
pip.exe install PackageName
