我一直在按照文档操作，直到安装requirements.txt文件这一步。但是在尝试安装第六行"psycopg2==2.5.3"时总是失败了。以下是错误信息 -

当然，我在这里发现了一些帖子。 所以我开始检查事情。 我相信Mac的postgres app附带了psycopg2。 我已经将postgres添加到我的路径中，并在终端中运行“echo $ PATH”进行了检查。 我没有任何其他旧版本的冲突。 而且postgres文档说我应该像这样将其添加到路径中 -
我已经重新启动了postgres应用程序，停用并重新启动了虚拟环境，但无论如何我都会收到相同的错误。export PATH =“/ Applications / Postgres.app / Contents / Versions / 9.3 / bin：$ PATH：$ PATH”
我可能忽略了什么！ 我已经阅读并阅读了其他帖子，甚至涵盖此问题的博客。
