python3如何安装pip,为python3.3安装pip

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).
