I want to use a new feature of httpie. This feature is in the github repo https://github.com/jkbr/httpie but not in the release on the python package index https://pypi.python.org/pypi/httpie
How can I install the httpie package from the github repo? I tried
pip install https://github.com/jkbr/httpie
But I got an error 'could not unpack'
In Nodejs, I can install packages from github like this
npm install git+https://github.com/substack/node-optimist.git
