The correct solution is to install newt, not snack which is a scientific visualization library. The "snack" dependency of newt refers to snack.py file in newt library, not to be confused with the snack library (which is a scientific visualisation library). snack.py offers windowing abilities for byobu-config.

To install using conda, https://anaconda.org/conda-forge/newt

conda install -c conda-forge newt

This worked for me:

sudo zypper in python3-newt

If you're on another distro, try installing python3-newt using your package manager and it should fix the problem.

Old one, I know, but this particular error is because you were trying to install a Python 2 module with Python 3's Pip. A tell-tale sign is the error being about print statement which is a function in Python 3.

About the error code

According to the Python documentation:

This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive.

Error code 1 is defined in errno.h and means Operation not permitted.

About your error

Your setuptools do not appear to be installed. Just follow the Installation Instructions from the PyPI website.

If it's already installed, try

pip install --upgrade setuptools

If it's already up to date, check that the module ez_setup is not missing. If it is, then

pip install ez_setup

Then try again

pip install snack

If it's still not working, maybe pip didn't install/upgrade setup_tools properly so you might want to try
