The easiest way to install pip for PyPy on any operating system is to use the ensurepip package that comes with Python and PyPy by default. Pip can now be installed by doing the following: Download the latest version of get-pip.py from https://bootstrap.pypa.io/.
To create a virtual environment, go to your project's directory and run venv. If you are using Python 2, replace venv with virtualenv in the below commands. The second argument is the location to create the virtual environment. Generally, you can just create this in your project and call it env .
Looking back, PyPy did not have support for Pandas and NumPy a couple of years ago, but it supports them now. So, there is a possibility that more libraries will support or be supported by PyPy in the future, but definitely not in near future.
This appears to be a regression in 1.8.4. While trying this out on my system everything worked fine with virtualenv 1.8.2, then I upgraded and now I get the same error as you.
