How do I install pytest to be used in pypy? Already installed with standard python

arkadiusz@pc:~$ pip install pytest
Requirement already satisfied (use --upgrade to upgrade): pytest in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): py>=1.4.29 in ./.local/lib/python2.7/site-packages (from pytest)

but cannot run

arkadiusz@pc:~$ pypy -m pip install pytest
/usr/bin/pypy: No module named pip

cannot install pip

arkadiusz@pc:~$ pypy -m ensurepip
ensurepip is disabled in Debian/Ubuntu for the system python.

Python modules For the system python are usually handled by dpkg and apt-get.

    apt-get install pypy-<module name>

Install the python-pip package to use pip itself.  Using pip together
with the system python might have unexpected results for any system installed
module, so use it on your own risk, or make sure to only use it in virtual

The ensurepip suggests using apt-get but apt does not have pip or pytest for pypy.

arkadiusz@pc:~$ sudo apt-get install pypy
