To use PyWPS 4 the third party libraries GIT and GDAL need to be installed in the system.
In Debian based systems these can be installed with:
$ sudo apt-get install git python-gdal
In Windows systems a Git client should be installed (e.g. GitHub for Windows).
Using pip:
$ sudo pip install -e git+https://github.com/geopython/pywps.git@main#egg=pywps
Or in alternative install it manually:
$ git clone https://github.com/geopython/pywps.git
$ cd pywps/
$ sudo pip install .
$ git clone https://github.com/geopython/pywps-flask.git pywps-flask
$ python demo.py
