How to install python3 version of package via pip

Question

I have both python2.7 and python3.2 installed in Ubuntu 12.04.
The symbolic link python links to python2.7.

When I type:

sudo pip install package-name

It will default install python2 version of package-name.

Some package supports both python2 and python3.
How to install python3 version of package-name via pip?

Answer 1

The easiest way to install latest pip2/pip3 and corresponding packages:

curl https://bootstrap.pypa.io/get-pip.py | python2
pip2 install package-name    

curl https://bootstrap.pypa.io/get-pip.py | python3
pip3 install package-name

^{Note: please run these commands as root}

Answer 2

Well, on ubuntu 13.10/14.04, things are a little different.

Install

$ sudo apt-get install python3-pip

Install packages

$ sudo pip3 install packagename

NOT pip-3.3 install

Answer 3

Another way to install python3 is using wget. Below are the steps for installation.

wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install

Also,one can create an alias for the same using

echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc

Now open a new terminal and type py and press Enter.

Answer 4

If you have pip installed in both pythons, and both are in your path, just use:

$ pip-2.7 install PACKAGENAME
$ pip-3.2 install PACKAGENAME
