Make sure that you have the following:
sudo apt-get install python-dev python-tk # If using Debian/Ubuntu sudo yum install python-devel tkinter # If using Fedora
sudo pip install nymphemeral
If you do not use pip, you at least have to install setuptools. It provides a few features needed by nymphemeral and will also automatically install the dependencies mentioned above. After making sure you have setuptools, install with:
git clone https://github.com/felipedau/nymphemeral cd nymphemeral/ sudo python setup.py install
nymphemeral and its dependencies should be installed.
nymphemeral will be ready for use after installation via either of the two methods described in Main Dependencies. However, you should follow the instructions from Connections, install Mixmaster and have a News Server running to be able to use all of its features.
If you installed nymphemeral with pip, you can also use it for updates:
sudo pip install --upgrade nymphemeral
