Written in Python 2.7. Tested in Windows 8.1 and Ubuntu 16.04.
If you don't have pip installed, do it.
Altough not necessary, I advise you to use a virtual environment.
Ok, now, in a terminal, go to the root of the project and enter:
pip install -r requirements.txt
This will install all the dependencies needed to run the program. If you're on Windows, the installation of lxml will probably raise an error. If this happens, go to this page and download the file that corresponds to your needs. I, for example, downloaded the file called lxml-3.6.4-cp27-cp27m-win32.whl. In a terminal, go to the folder where you saved this file and enter this:
pip install lxml-3.6.4-cp27-cp27m-win32.whl
Then go back to the root of the project and do pip install -r requirements.txt once again, so that everything is installed correctly.
You'll have to run the program in a shell that supports bash. I've tested in Cygwin (2.5.2) and Git BASH. Go to the root of the project and enter:
python pcrawler_service.py
This will start a flask server on http://localhost:5001/passatempos . You can go to this URL to check if everything is working alright. You should see a JSON. If it takes a while to load it could be because it's running all the spiders.
The webservice only accepts GET requests to the URL above. You can find a front-end interface for this project here.
