Homebrew 安装 postgresql 失败； python 64位错误

Question

我在运行时遇到错误

$ brew install postgresql

==> Downloading http://ftp.postgresql.org/pub/source/v9.1.2/postgresql-9.1.2.tar.bz2
File already downloaded in /Users/neil/Library/Caches/Homebrew
Warning: Detected a framework Python that does not have 64-bit support in:
/Library/Frameworks/Python.framework/Versions/Current/Python

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.

te that a framework Python in /Library/Frameworks/Python.framework is

这里是python所在的地方。

$ which 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

虽然我遇到了 python 64 位错误，但根据这个 SO post，我的 python 版本是 64 位的：

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

64

Answer 1

referenced mailing list post 中指出的问题是配置步骤不受此处 PATH 的影响。还有一个完整的其他机制用于查找要链接的东西。请参阅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，以将其从链接器的搜索路径中取出，重复brew install，然后放回去。

Answer 2

如果您的 PostgreSQL 中不需要 Python 绑定，您也可以使用 brew install postgresql --no-python 在不使用 Python 绑定的情况下安装它。

Answer 3

此命令正在安装服务器，而不是 python 绑定。那是你要的吗？有一个installer for osx 会为你安装服务器。

完成此操作后，您可以安装 psycopg2 绑定 directly from source。
