The next step would be to create something like a virtual environment and install the dependencies of this package inside it.
Create and enter the virtual environment
# With virtualenv (on Unix and OSx)mkdirmy-amazing-solar-project
cdmy-amazing-solar-project
virtualenvvirtualEnvName
sourcevenv/bin/activate
# With virtualenv (on Windows)mkdirmy-amazing-solar-project
cdmy-amazing-solar-project
virtualenvvirtualEnvName
.\venv\Scripts\activate.bat
Once inside the virtualenv, you can proceed to install dependencies.
python-mpipinstall-e."[dev]"
Dependencies are now installed, you can now run the tests to see if everything is running as it should.
