How to install pip for Python 3 on Mac OS X?

OS X (Mavericks) has Python 2.7 stock installed. But I do all my own personal Python stuff with 3.3. I just flushed my 3.3.2 install and installed the new 3.3.3. So I need to install pyserial again. I can do it the way I've done it before, which is:

Download pyserial from pypi
untar pyserial.tgz
cd pyserial
python3 setup.py install

But I'd like to do like the cool kids do, and just do something like pip3 install pyserial. But it's not clear how I get to that point. And just that point. Not interested (unless I have to be) in virtualenv yet.

UPDATE: This is no longer necessary with Python3.4. It installs pip3 as part of the stock install.

I ended up posting this same question on the python mailing list, and got the following answer:

# download and install setuptools
curl -O https://bootstrap.pypa.io/ez_setup.py
python3 ez_setup.py
# download and install pip
curl -O https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py

Which solved my question perfectly. After adding the following for my own:

cd /usr/local/bin
ln -s ../../../Library/Frameworks/Python.framework/Versions/3.3/bin/pip pip

So that I could run pip directly, I was able to:

# use pip to install
pip install pyserial

or:

# Don't want it?
pip uninstall pyserial

I had to go through this process myself and chose a different way that I think is better in the long run.

I installed homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

then:

brew doctor

The last step gives you some warnings and errors that you have to resolve. One of those will be to download and install the Mac OS X command-line tools.

then:

brew install python3

This gave me python3 and pip3 in my path.

pieter$ which pip3 python3
/usr/local/bin/pip3
/usr/local/bin/python3

Install Python3 on mac

1. brew install python3
2. curl https://bootstrap.pypa.io/get-pip.py | python3
3. python3

Use pip3 to install modules

1. pip3 install ipython
2. python3 -m IPython

Plus: when you install requests with python3, the command is:

pip3 install requests

not

pip install requests

brew install python3
create alias in your shell profile
- eg. alias pip3="python3 -m pip" in my .zshrc

➜ ~ pip3 --version

pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

To use Python EasyInstall (which is what I think you're wanting to use), is super easy!

sudo easy_install pip

so then with pip to install Pyserial you would do:

pip install pyserial

Also, it's worth to mention that Max OSX/macOS users can just use Homebrew to install pip3.

$> brew update
$> brew install python3
$> pip3 --version
pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

pip is installed automatically with python2 using brew:

brew install python3
pip3 --version

On Mac OS X Mojave python stands for python of version 2.7 and python3 for python of version 3. The same is pip and pip3. So, to upgrade pip for python 3 do this:

~$ sudo pip3 install --upgrade pip

Lincoln

On MacOS 10.12

download pip: pip as get-pip.py

download python3: python3

install python3
open terminal: python3 get-pip.py
pip3 is available

For a fresh new Mac, you need to follow below steps:-

Make sure you have installed Xcode
sudo easy_install pip
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew doctor
brew doctor
brew install python3

And you are done, just type python3 on terminal and you will see python 3 installed.

Here is my simple solution:

If you have python2 and python3 both installed in your system, the pip upgrade will point to python2 by default. Hence, we must specify the version of python(python3) and use the below command:
