still works as before, only that now it requires tox to be available in the /home/clupo/.pyenv/plugins/pyenv-virtualenv/shims:/home/clupo/.pyenv/shims:/home/clupo/.pyenv/bin:/home/clupo/.pyenv/plugins/pyenv-virtualenv/bin:/home/clupo/.local/bin:/home/clupo/bin:/home/clupo/.cargo/bin:/home/clupo/Applications/node-v6.11.4-linux-x64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin, else it will fail
