在这里完成新手操作，尝试将Django设置为可与PostgreSQL一起使用。

我正在使用Mac OS X 10.6.8。我还安装了PostgreSQL 9.3

pip install psycopg2在终端中运行时，出现以下错误

回答：

我建议你尝试使用Postgres.app。（http://postgresapp.com）这样，你可以轻松地在Mac上打开和关闭Postgres。完成后，.profile通过添加以下内容，将Postgres的路径添加到文件中：

PATH="/Applications/Postgres.app/Contents/Versions/latest/bin:$PATH"

只有将Postgres添加到路径后，才能尝试psycopg2在虚拟环境中（使用pip）或全局站点包中进行安装。
