How to install pip with Python 3?

Question

I want to install pip. It should support Python 3, but it requires setuptools, which is available only for Python 2.

How can I install pip with Python 3?

Answer 1

If you use several different versions of python try using virtualenv http://www.virtualenv.org/en/latest/virtualenv.html#installation

With the advantage of pip for each local environment.

Then install a local environment in the current directory by:

virtualenv -p /usr/local/bin/python3.3 ENV --verbose

Note that you specify the path to a python binary you have installed on your system.

Then there are now an local pythonenvironment in that folder. ./ENV

Now there should be ./ENV/pip-3.3

use ./ENV/pip-3.3 freeze to list the local installed libraries.

use ./ENV/pip-3.3 install packagename to install at the local environment.

use ./ENV/python3.3 pythonfile.py to run your python script.

Single Python in system

To install packages in Python always follow these steps:

1. If the package is for python 2.x: sudo python -m pip install [package]
2. If the package is for python 3.x: sudo python3 -m pip install [package]

Note: This is assuming no alias is set for python

Through this method, there will be no confusion regarding which python version is receiving the package.

Multiple Pythons

Say you have python3 ↔ python3.6 and python3.7 ↔ python3.7

1. To install for python3.6: sudo python3 -m pip install [package]
2. To instal for python3.7: sudo python3.7 -m pip install [package]

This is essentially the same method as shown previously.

Note 1

How to find which python, your python3 command spawns:

ganesh@Ganesh:~$ python3 # Type in terminal
Python 3.6.6 (default, Sep 12 2018, 18:26:19) # Your python3 version
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

Notice python 3.6.6 in the second line.

This is what I did on OS X Mavericks to get this to work.

Firstly, have brew installed

Install python 3.4

brew install python3

Then I get the latest version of distribute:

wget https://pypi.python.org/packages/source/d/distribute/distribute-0.7.3.zip#md5=c6c59594a7b180af57af8a0cc0cf5b4a

unzip distribute-0.7.3.zip
cd distribute-0.7.3
sudo setup.py install
sudo easy_install-3.4 pip
sudo pip3.4 install virtualenv
sudo pip3.4 install virtualenvwrapper

mkvirtualenv py3 

python --version
Python 3.4.1

I hope this helps.
