Installing pip for python3.3

问题:

I downloaded pip from Package Index > pip 1.2.1

Then I installed it using

sudo python3.3 setup.py install

Still, when I try to use pip-3.3 the terminal complains

-bash: pip-3.3: command not found

However, pip-2.7 works swimmingly.

I have also tried

curl -O http://python-distribute.org/distribute_setup.py
sudo python3.3 distribute_setup.py
sudo python3.3 -m easy_install pip

But pip-3.3 still does not work.

What do I do to install pip for Python 3.3?

Note that there is a related thread How to install pip with Python 3?, but the answer is just "Install distribute ... and then use that to install pip" which is not helpful to me because I have tried it and it did not work.

Chances are that pip did get installed successfully somewhere. However, somewhere is probably not on your PATH and so you shell (bash) doesn't know where to find it. For me, pip-2.6 is installed in:

/Library/Frameworks/Python.framework/Versions/2.6/bin/

It is probably a similar path for you (only 3.3 instead of 2.6). Of course, adding to PATH is shell dependent. On bash-like shells you'd use export and on csh-like shells you'd use setenv -- And for convenience, you'd probably want to make the change in your shell's initialization file (e.g ~/.bashrc or ~/.bash_profile or something similar).

One way to go is to use the homebrew install for python3. It comes with pip3 builtin. It also means you have an uninstaller unlike the dmg/pkg install.

If you have homebrew already its as easy as brew install python3. More detailed instructions here. And you can read more about the python3 brew install here.

For Mac:

sudo easy_install pip3

If you still run into trouble, possibly because you compiled python3 yourself, use apt-get or homebrew to uninstall your compilation and reinstall the python3 package, at which point it should come with pip.

brew uninstall python3
brew install python3
brew link --overwrite python3

curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | sudo python3.3

If pip is actually installed, it can always be invoked via the versioned Python command like this:

python3.3 -m pip
