 Since all scripts chain the invocation with the same interpreter as originally invoking the script, you will need to install py.test for PyPy.
 Assuming that you already have PyPy installed, you can simply install py.test using these commands:
 ```sh
-wget https://bootstrap.pypa.io/get-pip.py
+wget https://msdl.uantwerpen.be/files/get-pip.py
 pypy get-pip.py --user
 pypy -m pip install pytest --user
