Begin by setting up a virtual environment with Python 2.7 for Jython compatibility. Note that necessary headers are required to build libraries with pip. For instance, using virtualenv:

```bash
$ sudo apt install -y python2.7 python2.7-dev python2-setuptools-whl python2-pip-whl python3-virtualenv
$ sudo apt install -y python2.7 python2.7-dev python2-setuptools-whl python2-pip-whl python3-virtualenv libssl-dev
$ virtualenv -p python2.7 ./venv/
