我正在尝试构建我的第一个 Django 应用程序，但在最初的尝试中我无法让数据库正确同步。

我收到以下错误：

c:\mysite>manage.py syncdb

ImportError: DLL load failed: %1 is not a valid Win32 application.

我究竟做错了什么？

我已经安装了 Python 2.7、Postgres 9.1.3.1、psycopg 2.4.5（匹配 2.7 和 9.1.3）。

ImportError: DLL load failed: %1 is not a valid Win32 application.

看起来你的机器和 Python/Postgres/psycopg 的架构不匹配。例如，如果您使用的是 32 位架构，但尝试安装 64 位代码。

检查这篇文章作为另一个有同样问题的人的例子。这似乎实际上可能是python版本问题。尝试使用您正在使用的其他版本安装 python。
