如果安装了多个Python，MacPorts如何知道要为其安装MySQLdb? [英] With multiple Python installs, how does MacPorts know which one to install MySQLdb for?

问题描述

我刚刚通过www.python.org上的安装程序将Leopard上的默认Python 2.5升级到2.6.这样做后，不再找到我已安装的MySQLdb.因此，我尝试通过 port install py-mysql 重新安装它，但成功了，但是MySQLdb仍然不能 import .因此，然后我尝试使用 python_select python26 python install python26 并成功，但似乎没有优先于python.org安装:

I just upgraded the default Python 2.5 on Leopard to 2.6 via the installer on www.python.org. Upon doing so, the MySQLdb I had installed was no longer found. So I tried reinstalling it via port install py-mysql, and it succeeded, but MySQLdb was still not importable. So then I tried to python install python26 with python_select python26 and it succeeded, but it doesn't appear that it is getting precedence over the python.org install:

$ which python
/Library/Frameworks/Python.framework/Versions/2.6/bin/python

当我期望它像/opt/local/bin/python

我的 path 环境是:/Library/Frameworks/Python.framework/Versions/2.6/bin:/usr/local/mysql/bin/:/opt/local/bin:/opt/本地/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/mysql/bin:/Users/bsr/bin

无论如何，当我尝试 port install py-mysql 时，它怎么知道在哪里安装Python MySQL库?

Anyway, when I try port install py-mysql but how does it know where to install the Python MySQL library?

推荐答案

MacPorts python端口通常遵循以下模式:如果端口名称仅以 py-开头，它配置为安装到MacPorts python2.4中.同样， py25-需要python2.5.对于 MacPorts python2.6，你想要这个端口:

The MacPorts python ports generally follow a pattern: if the port name starts with just py-, it is configured to install into MacPorts python2.4. Likewise py25- requires python2.5. For the MacPorts python2.6, you want this port:

sudo port install py26-mysql
