Easy_install the wrong version of python modules (Mac OS)

I installed Python 2.7 on my Mac. When typing "python" in terminal, it shows:

$ python
Python 2.7 (r27:82508, Jul  3 2010, 20:17:05) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

The Python version is correct here.

But when I try to easy_install some modules. The system will install the modules with python version 2.6 which are not able be imported to Python 2.7. And of course I can not do the functions I need in my code. Here's an example of easy_install graphy:

$ easy_install graphy

Adding Graphy 1.0.0 to easy-install.pth file

Finished processing dependencies for graphy

So it installs graphy for Python 2.6.

Can someone help me with it? I just want to set my default easy_install Python version to 2.7.

1What happens when you type which python and which easy_install? How did you install Python 2.7, how did you install easy_install? – Daniel Beck – 2011-03-12T16:20:04.960

Ma-Xiaolongs-MacBook-Pro-2:~ MaXiaolong$ which python /Library/Frameworks/Python.framework/Versions/2.7/bin/python Ma-Xiaolongs-MacBook-Pro-2:~ MaXiaolong$ which easy_install /usr/bin/easy_install – user73250 – 2011-03-13T03:55:07.443

I just download the python 2.7 and install the python. But I have no idea how I installed easy_install.. I thought it comes with python.. I'm new to python, sorry about that. Can you help me to think about how to fix the problem? Really appreciate it. – user73250 – 2011-03-13T03:57:26.007

It seems that your installation of setuptools is obsolete.

If you want your "easy_install" match your updated python version, follow these steps:

Download the corresponding .egg file at http://pypi.python.org/pypi/setuptools#files
Run it as if it were a shell script: sh setuptools-0.6c9-py2.7.egg

This will install the new "easy_install" executable, compatible with your current version of python.

Hope this helps.

Not sure if this is what you are looking for, but if you command+i a python file you can change which version you want the file to be opened with.

really thank you for your answer. But this doesn't solve my problem. My problem is not run the code with a wrong version. It's easy_install in the wrong version of python. Anyway, thank you all the same : ) – user73250 – 2011-03-13T15:18:34.203

The solution by fjavieralba did not work for me. What did work was installing easy_install using the tarball.

Download tarball from http://pypi.python.org/pypi/setuptools#files (I placed it in /tmp/)
Extract it using the command tar -zxvf setuptools-0.6c11.tar.gz
cd /setuptools-0.6c11
install it with the python I want easy_install to work with (2.7, which in my case was under /usr/local/bin/python.

This was with:

/usr/local/bin/python setup.py build
/usr/local/bin/python setup.py install

And finally I can use east_install to get the package I want. For python2.7:

easy_install-2.7 *NAME*

or, for python 2.6:

easy_install-2.6 *NAME*
