python - 在带有 Python2.6 的 Mac 上并尝试安装 psycopg2

Question

我是 Python 新手。我现在运行 Python2.6。我正在关注 Python 网站上的教程。我的问题是当我尝试按照此处的说明操作时:

http://py-psycopg.darwinports.com/

我得到了类似...

sudo port install py-psycopg
... bunch of errors here...
Error: The following dependencies failed to build: py-mx python24

我运行的是 MacOS X 10.4。

我该怎么做？

如有任何回复，我们将不胜感激。

更新:

运行下面的代码后，我得到以下错误:

$ sudo port install py26-psycopg2

仅供引用，我安装的 python 是来自 pythong 站点的 dmg 文件。

谢谢， 温伯特

如果您使用的是 Python 2.6，您实际上想要构建 py26-psycopg2:

$ sudo port install py26-psycopg2

在 MacPorts 中，py-* 包使用 Python 2.4 构建，py25-* 使用 Python 2.5，py26-* 使用 Python 2.6 .
