Installation did not work for me

[JonAhlquist]

Background: I am running 64-bit Fedora 29 Linux on a Dell laptop. I installed Python 3 using Fedora's "dnf install". I am a meteorologist who mainly uses Fortran 90 with gfortram but I am also learning Python 3.

When I tried to install py3grads using the instructions at GitHub, I received a syntax error. Because I am a Python beginner, I do not know how to fix the error. In any case, the posted installation commands don't run under Fedora 29's Python 3. Here are installation commands and the system replies that I received.

From the output, it appears you are trying to install the package under Python 2.7, which is probably still the system default for the root user on Fedora 29. Ensure that when you type "python setup.py install" that the python executable being run is actually Python 3. You can type which python to check the executable's path. Python 3 may be installed on the path /usr/bin/python3, for example, and you may need to call that executable directly.

Hi, I am wondering whether we have setup.py for this right now. I don't see the setup.py in here. Thanks.

This project now uses the standardized pyproject.toml, which supersedes the functionality of setup.py. The project can now be installed simply with pip install from inside the project directory or pip install git+https://github.com/meridionaljet/py3grads
