我知道有几个问题涉及这个问题，但我很难弄清楚，如果我的问题有一个解决方案。我使用的是Mac 10.6.8，MacPorts 2.1.3 在这里，我指的是one discussion here on SO，我的问题似乎已得到解决。这就是我所做的：
$ sudo port install py-rpy2 # seemed to be fine. A
$ python -m 'rpy2.tests' # gave the output
usr/bin/python: No module named rpy2
$ /opt/local/bin/python2.7 -m 'rpy2.tests # results in a
'Segmentation fault' # and MacOS is complaining..
升级所有过时的软件包后
$ sudo port -f uninstall py-rpy2
$ sudo port -f install py-rpy2
... the same as above.<br>
$ sudo easy_install rpy2
抛出许多错误并以
结束'error: Setup script exited with error: command 'gcc-4.2' failed with exit status 1'
您可以找到完整输出here。
我只有一个
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/
路径，2.7没有
/Library/Frameworks/Python.framework/Versions/
条目。
localhost:~$ ls /opt/local/bin/python*
/opt/local/bin/python2.4

$ which python

这是Python 2.6.1。
