If you want to fully install NAPALM you can do it by executing:
pip install napalm
That will install all the drivers currently available.
If you want to install just a subset of the available modules you can just pick them as follows:
pip install napalm-eos napalm-junos
That will install only the eos and the junos drivers. If you want to remove or add a module later on you can just use pip to do it:
pip uninstall napalm-junos pip install napalm-ios
Check the [‘Supported Network Operating Systems’](http://napalm.readthedocs.io/en/latest/support/index.html) section for more information about supported modules.

pip install napalm -U
pip install napalm-eos napalm-junos -U
