afew works with python 3.4+, and requires notmuch and its python bindings. On Debian/Ubuntu systems you can install these by doing:
$ sudo aptitude install notmuch python-notmuch python-dev python-setuptools
Note: if you are installing notmuch using Homebrew on macOS, make sure
$ brew install --with-python3 notmuch, because the brew formula
doesn’t install python3 notmuch bindings by default.
It is recommended to install afew itself inside a virtualenv as an unprivileged user, either via checking out the source code and installing via setup.py, or via pip.
# create and activate virtualenv $ python -m venv --system-site-packages .venv $ source .venv/bin/activate # install via pip from PyPI: $ pip install afew # or install from source: $ python setup.py install --prefix=~/.local
You might want to symlink .venv/bin/afew somewhere inside your path (~/bin/ in this case):
$ ln -snr .venv/bin/afew ~/.bin/afew
