Ensuring pip modules work smoothly post pypy installation (after trying ensurepip option)

[87sam12]

Im using anaconda's pip as a command line default and have quite a lot of packages already. I just want to make sure the pypy installation done using pip can access these same modules without reinstallations. Is there a quick and easy way?
I tried this way (https://docs.python.org/3/library/ensurepip.html) and Im unable to provide the default pip if I try
./pypy3-c -m ensurepip --default-pip "~/anaconda/bin/pip"

python -m ensurepip: error: unrecognized arguments: ~/anaconda/bin/pip
