Installation#

Stable release#

nway is a pure Python program.

To install nway, run this command in your terminal:

$ pip install nway

This is the preferred method to install nway, as it will always install the most recent stable release.

The command line tool nway.py is installed for you as ~/.local/bin/nway.py.

If that directory is in your $PATH, you can run:

$ nway.py --help

If you don’t have pip installed, this Python installation guide can guide you through the process.

To upgrade, uninstall the older Nway version first:

$ pip uninstall nway

Repeat until it says that nway is not installed. Then follow the installation instructions above.
