I am trying to use python package manager pip to install a package and it's dependencies from the internet. However I am behind a proxy in my college and have already set the http_proxy environment variable. But when I try to install a package like this:
pip install TwitterApi I get this error in the log file:
Getting page http://pypi.python.org/simple/TwitterApi Could not fetch URL http://pypi.python.org/simple/TwitterApi: <urlopen error [Errno 111] Connection refused> Will skip URL http://pypi.python.org/simple/TwitterApi when looking for download links for TwitterApi Getting page http://pypi.python.org/simple/ Could not fetch URL http://pypi.python.org/simple/: <urlopen error [Errno 111] Connection refused> I even tried setting my proxy variable explicitly like this:
pip install --proxy http://user:password@proxyserver:port TwitterApi But I still get the same error. How do I get pip to work behind a proxy server.

pip can be configured to connect through a proxy server in various ways: using the --proxy command-line option to specify a proxy in the form scheme://[user:passwd@]proxy.server:port. using proxy in a Configuration Files. by setting the standard environment-variables http_proxy , https_proxy and no_proxy .
A proxy server for pip is most commonly used for security and privacy, but can also be used for control: Security & Privacy – a proxy server can be used in combination with firewalls in order to improve internal network security since requests from users on the local network are anonymized via a proxy server.
To use a proxy in Python, first import the requests package. Next create a proxies dictionary that defines the HTTP and HTTPS connections. This variable should be a dictionary that maps a protocol to the proxy URL. Additionally, make a url variable set to the webpage you're scraping from.
By default pip installs third party packages from the Python Package Index (PyPI). In corporate environments located behind a firewall, you may require the use of an HTTP proxy server to redirect internal traffic to pypi.org, or any other repository that hosts Python packages.

You can also set up the proxy through comand lines: After setting up proxies, then you can install packages through running: Alternativelly, you can also specify proxy settings in the pip command: and then install package:
It looks like you need to use a proxy but don't setup the proxy with get-pip.py. That's why it fails. According to the documentation get-pip.py should be given the proxy in the following way: Thanks for contributing an answer to Server Fault!
Following settings and commands can be used to make ‘pip install’ work smoothly. You can manually set up proxy environment variables through right-click on This PC (Windows 10) or Computer (Widnows 7) –> Proporties –> Advanced system settings –> Environment variables then add environment variables:
The pip's proxy parameter is, according to pip --help, in the form scheme://[user:passwd@]proxy.server:port
You should use the following:
pip install --proxy http://user:password@proxyserver:port TwitterApi Also, the HTTP_PROXY env var should be respected.
Note that in earlier versions (couldn't track down the change in the code, sorry, but the doc was updated here), you had to leave the scheme:// part out for it to work, i.e. pip install --proxy user:password@proxyserver:port
