If you want to install a bunch of dependencies from, say a requirements.txt, you would do:
mkdir dependencies
pip download -r requirements.txt -d "./dependencies"
tar cvfz dependencies.tar.gz dependencies
And, once you transfer the dependencies.tar.gz to the machine which does not have internet you would do:
tar zxvf dependencies.tar.gz
cd dependencies
pip install * -f ./ --no-index
On the machine where I have access to Internet:
mkdir keystone-deps
pip download python-keystoneclient -d "/home/user/keystone-deps"
tar cvfz keystone-deps.tgz keystone-deps
Then move the tar file to the destination machine that does not have Internet access and perform the following:
tar xvfz keystone-deps.tgz
cd keystone-deps
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index
You may need to add --no-deps to the command as follows:
pip install python_keystoneclient-2.3.1-py2.py3-none-any.whl -f ./ --no-index --no-deps
