Question

我一直在关注文档，直到我开始安装requirements.txt文件。尝试安装第6行“psycopg2 == 2.5.3”时总是会失败。这是消息 -

Downloading/unpacking psycopg2==2.5.3 (from -r requirements.txt (line 6))

当然我发现了几个帖子。所以我开始检查事情。我相信mac的postgres应用程序带有psycopg2。我确实已将postgres添加到我的路径并在终端中运行“echo $ PATH”。我没有任何其他旧版本冲突。 postgres文档说我应该把它添加到我的路径中 -

export PATH =“/ Applications / Postgres.app / Contents / Versions / 9.3 / bin：$ PATH：$ PATH”

我重新启动了postgres应用程序，停用并重新启动了虚拟环境，无论如何我都得到了同样的错误。

我可能会俯瞰什么！我已阅读并阅读此处的其他帖子，甚至还有关于此问题的博客。

在阅读了几十个相同的错误后，人们都在使用postgres mac app。我决定通过brew安装postgres，现在一切正常。
