Question

运行时出现错误

$ brew install postgresql

e configure script seems to prefer this version of Python over any others,
 you may experience linker problems as described in:
http://osdir.com/ml/pgsql-general/2009-09/msg00160.html

 fix this issue, you may need to either delete the version of Python
own above, or move it out of the way before brewing PostgreSQL.

这是 python 所在的位置。

$ 哪个 python

/usr/local/bin/python

我修改了我的 ~/.zshrc 路径

export PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

到

export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

虽然我收到 python 64 位错误，但根据此 SO post，我的 python 版本是 64 位的:

$ python -c 'import struct;print( 8 * struct.calcsize("P"))'

64

referenced mailing list post中指出的问题是这里的配置步骤不受 PATH 的影响。还有一种用于查找要链接的内容的其他机制；见Where do I set DYLD_LIBRARY_PATH on Mac OS X快速介绍。您可以尝试 brew 脚本给出的建议解决方法——将 /Library/Frameworks/Python.framework/Versions/Current/Python 重命名为其他内容以使其脱离链接器的搜索路径，重复brew install，然后放回去。
