尝试导入psycopg2时出现此错误。。我找了好几天都没找到解决办法。 我尝试安装VisualC++ 2008包，但仍然有同样的错误。

Answer 1

根据这个thread您需要安装一个早期版本，因为最新的版本有问题。

Simply install an earlier version, (2.0.10 works great), even with PostgreSQL 8.4.x series.

Answer 2

您还可以尝试从here安装win psycopg

Answer 3

在Windows上，请确保您的路径包含Postgres bin目录。在我的机器里是c:\程序\ PostgreSQL\9.3\bin。
