python-3.x mac - How to install python3 version of package via pip on Ubuntu?
unable locate (14)
Firstly, you need to install pip for the Python 3 installation that you want. Then you run that pip to install packages for that Python version.
Since you have both pip and python 3 in /usr/bin, I assume they are both installed with a package manager of some sort. That package manager should also have a Python 3 pip. That's the one you should install.
Felix' recommendation of virtualenv is a good one. If you are only testing, or you are doing development, then you shouldn't install the package in the system python. Using virtualenv, or even building your own Pythons for development, is better in those cases.
But if you actually do want to install this package in the system python, installing pip for Python 3 is the way to go.

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

sudo apt-get install python3-pip sudo pip3 install MODULE_NAME
Source: Shashank Bharadwaj's comment
The short answer applies only on newer systems. On some versions of Ubuntu the command is
sudo pip-3.2 install MODULE_NAME
If it doesn't work, this method should work for any Linux distro and supported version:
sudo apt-get install curl curl https://bootstrap.pypa.io/get-pip.py | sudo python3 sudo pip3 install MODULE_NAME
If you don't have
wget. If you don't have
sudo, switch to
pip3 symlink does not exists, check for something like pip-3.X
Much python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Check also Tobu's answer if you want an even more upgraded version of Python.
I want to add that using a virtual environment is usually the preferred way to develop a python application, so @felixyan answer is probably the best in an ideal world. But if you really want to install that package globally, or if need to test / use it frequently without activating a virtual environment, I suppose installing it as a global package is the way to go.
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.
You may want to build a
virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)
This could be something like:
virtualenv -p /usr/bin/python3 py3env source py3env/bin/activate pip install package-name
You can alternatively just run
pip3 install packagename instead of
Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package
python-pip for Python 3. So here is what I've done (all commands were executed as root):
setuptoolsfor Python3 in case you haven't.
apt-get install python3-setuptools
aptitude install python3-setuptools
With Python 2.4+ you can invoke
easy_installwith specific Python version by using
python -m easy_install. So
pipfor Python 3 could be installed by:
python3 -m easy_install pip
That's it, you got
pipfor Python 3. Now just invoke
pipwith the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:
pip-3.2 install [package]
Ubuntu 12.10+ and Fedora 13+ have a package called
python3-pip which will install
pip3 for newer versions) without needing this jumping through hoops.
I came across this and fixed this without needing the likes of
wget or virtualenvs (assuming Ubuntu 12.04):
- Install package
sudo aptitude install python3-setuptools, this will give you the command
- Install pip using Python 3's setuptools: run
sudo easy_install3 pip, this will give you the command
pip-3.2like kev's solution.
- Install your PyPI packages: run
sudo pip-3.2 install <package>(installing python packages into your base system requires root, of course).
The easiest way to install latest
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
If you just installed Python 3.3 and now want to install pip 3.3 locally:
wget http://python-distribute.org/distribute_setup.py python3.3 -m distribute_setup install --user easy_install-3.3 --user pip
This works in Ubuntu 12.04. Don't forget to add
$HOME/.local/bin to your path.
Execute the pip binary directly.
First locate the version of PIP you want.

You should install ALL dependencies:
sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base
Install pip3(if you have installed, please look step 3):
sudo apt-get install python3-pip
Iinstall scikit-learn by pip3
pip3 install -U scikit-learn
Open your terminal and entry python3 environment, type
import sklearnto check it.
Although the question relates to Ubuntu, let me contribute by saying that I'm on Mac and my
python command defaults to Python 2.7.5. I have Python 3 as well, accessible via
python3, so knowing the pip package origin, I just downloaded it and issued
sudo python3 setup.py install against it and, surely enough, only Python 3 has now this module inside its site packages. Hope this helps a wandering Mac-stranger.
1) If you have installed Python 3.4 or later, pip is included with Python and should already be working on your system.
2) If you are running a version below Python 3.4 or if pip was not installed with Python 3.4 for some reason, then you'd probably use pip's official installation script
get-pip.py. The pip installer now grabs setuptools for you, and works regardless of architecture (32-bit or 64-bit).
The installation instructions are detailed here and involve:
To install or upgrade pip, securely download get-pip.py.
Then run the following (which may require administrator access):
To upgrade an existing setuptools (or distribute), run
pip install -U setuptools
I'll leave the two sets of old instructions below for posterity.
For Windows editions of the 64 bit variety - 64-bit Windows + Python used to require a separate installation method due to ez_setup, but I've tested the new distribute method on 64-bit Windows running 32-bit Python and 64-bit Python, and you can now use the same method for all versions of Windows/Python 2.7X:
OLD Method 2 using distribute:
- Download distribute - I threw mine in
C:\Python27\Scripts(feel free to create a
Scriptsdirectory if it doesn't exist.
- Open up a command prompt (on Windows you should check out conemu2 if you don't use PowerShell) and change (
cd) to the directory you've downloaded
- Run distribute_setup:
python distribute_setup.py(This will not work if your python installation directory is not added to your path - go here for help)
- Change the current directory to the
Scriptsdirectory for your Python installation (
C:\Python27\Scripts) or add that directory, as well as the Python base installation directory to your %PATH% environment variable.
- Install pip using the newly installed setuptools:
The last step will not work unless you're either in the directory
easy_install.exe is located in (C:\Python27\Scripts would be the default for Python 2.7), or you have that directory added to your path.
OLD Method 1 using ez_setup:
Download ez_setup.py and run it; it will download the appropriate .egg file and install it for you. (Currently, the provided .exe installer does not support 64-bit versions of Python for Windows, due to a distutils installer compatibility issue.
After this, you may continue with:
c:\Python2x\Scriptsto the Windows path (replace the
Python2xwith the actual version number you have installed)
- Open a new (!) DOS prompt. From there run
