python - 如何在 MacOs X 10.5 上安装 plpython？

Question

我刚刚在 Mac OS X 10.5(使用端口)上安装了 PostgreSQL 8.3.4，但我不知道如何启用 PL/Python。当我运行 CREATE LANGUAGE plpythonu 时，出现以下错误:

ERROR:  could not access file "$libdir/plpython": No such file or directory
STATEMENT:  CREATE LANGUAGE plpythonu;
psql:<stdin>:18: ERROR:  could not access file "$libdir/plpython": No such file or directory

我该如何解决？理想情况下，我宁愿避免在没有 port 或类似的东西的情况下编译 Postgres。

Thia 运行 pg_config 的输出:

(几天前我刚从 Linux 切换到 Mac...在 Ubuntu 中，像过去那样可以正常工作，所以我很迷茫。)

Answer 1

愚蠢的我:

[lib/postgresql83] > variants postgresql83
 postgresql83 has the variants:
    universal
    python: add support for python
    krb5: add support for Kerberos 5 authentication
    perl: add Perl support

(我有universal。)

这意味着您必须安装正确的 PostgreSQL 变体才能使您的 python 函数运行起来。

$ sudo port install postgresql83 +python postgresql-server +python
