Install pip on pypy

问题:

I want to speed up my program so i'm trying to setup pypy + psycopg2cffi. This program opens a xml, parses it and then insert some data in a database. I'm using currently python3, postgresql and psycopg2 but this approaches is really slow. So i want to try run my program with pypy + psycopg2cffi. I have python 3 and pypy, and i want to install psycopg2cffi so i ran this command:

pip install psycopg2cffi psycopg2cffi-compat 

But psycopg2cffi was only installed on python because when i try to import psycopg2cffi on pypy this is the error i get:

ImportError: No module named psycopg2cffi

So i think i need to install pip first but i can figure out how to do this.

How can i install it on pypy? Thank you.

You can also try this (if it's not disabled in your Linux distribution):

pypy -m ensurepip

回答2:

Download the pip-installer and execute it with pypy:

wget https://bootstrap.pypa.io/get-pip.py
./pypy get-pip.py

For usage try,

pypy -m pip install validators
