How to install python, pip, and isitfit

To install isitfit with pip3:

pip3 install isitfit

and then just test that it's installed with

isitfit version


If you're new to python, here's some pip-fu for help.

Install Python on Ubuntu 18.04:

sudo apt-get install python3

Install pip on Ubuntu 18.04:

sudo apt-get install python3-pip

Alternatively, download Then run the following command to install it:


After having installed pip, there are 3 options to install isitfit:

sudo pip3 install pew  # install pew globally (on all computers around the world)
pew new -d isitfit_env # create a virtual environment and don't activate it yet
pew workon isitfit_env # explicitly activate the new environment
pip3 install isitfit   # install isitfit in the activated environment only
isitfit version        # use isitfit
exit                   # de-activate the environment
sudo pip3 install isitfit
pip3 install --user isitfit

Note that for the --user option, if you've just installed pip3, running isitfit version right after this step would yield an error command not found. Restarting the machine (or log off/log on?) would set the proper environment variables so that isitfit version would work.
