I installed Python 2.7 in my mac. When typing "python" in terminal, it shows: Ma-Xiaolongs-MacBook-Pro-2:~ MaXiaolong$ 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: Ma-Xiaolongs-MacBook-Pro-2:~ MaXiaolong$ easy_install graphy Searching for graphy Reading pypi.python.org/simple/graphy/ Reading http://code.google.com/p/graphy/ Best match: Graphy 1.0.0 Downloading http://pypi.python.org/packages/source/G/Graphy/Graphy- 1.0.0.tar.gz#md5=390b4f9194d81d0590abac90c8b717e0 Processing Graphy-1.0.0.tar.gz Running Graphy-1.0.0/setup.py -q bdist_egg --dist-dir /var/folders/fH/fHwdy4WtHZOBytkg1nOv9E+++TI/-Tmp-/easy_install-cFL53r/Graphy-1.0.0/egg-dist-tmp-YtDCZU warning: no files found matching '.tmpl' under directory 'graphy' warning: no files found matching '.txt' under directory 'graphy' warning: no files found matching '.h' under directory 'graphy' warning: no previously-included files matching '.pyc' found under directory '.' warning: no previously-included files matching '~' found under directory '.' warning: no previously-included files matching '.aux' found under directory '.' zip_safe flag not set; analyzing archive contents... graphy.all_tests: module references file Adding Graphy 1.0.0 to easy-install.pth file Installed /Library/Python/2.6/site-packages/Graphy-1.0.0-py2.6.egg Processing dependencies for graphy 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 version as 2.7... Thank you very much!!!!!!
