Question

在过去的几个月里，我一直在使用SQLite作为我的数据库，同时学习django并建立一个网站。我终于决定是时候切换到PostgreSQL，因为我正在接近生产。我已经被困了几天，在错误之后追逐错误，基本上查看所有其他帖子并试图让它工作，但我仍然没有运气。最近，我尝试了http://web.archive.org/web/20101221084639/http://nukeit.org/compile-python-2-7-packages-with-visual-studio-2010-express/，但我仍然遇到错误。运行pip install psycopg2时最新的回溯如下：

抱歉，如果它有点乱。在发布之前我试着尽可能地清理它。我对编程很新，而且我完全不知道还应该尝试什么。任何建议将不胜感激。在我的进展中，我已经看到了其他3个错误消息，并且不得不做其他几个下载试图使其工作。我愿意接受任何解决方案。

提前致谢。

我和你有类似的故事......几天来我试着把头撞到墙上。解决问题的最简单方法是查找/下载/安装预构建的软件包。您可以找到它们的列表（包括psycopg2）here。 - 感谢Christoph Gohlke保持这些。

作为参考，您可以在相关主题here上看到我的帖子。

最后，让我提供一条免费的建议。如果你真的想在Python / Django中工作，那么切换到Linux会更容易。可能有90％以上的博客文章或“如何做”假设您正在运行某些Linux版本。我首先从Oracle下载VirtualBox并在其中安装Ubuntu。很长一段时间这已经足够好了。但是，我最终切换到双启动设置，我不再进入Windows窗口了。希望这会有所帮助。
