根据此处的提示,旧的符号链接可能会混淆brew link,请尝试brew prune; brew link postgresql查看是否可以解决您的问题.

9.3.3是postgresql的旧版本,我没有看到你在Homebrew git历史中使用的Homebrew修订版？如果您brew update最近ð,有这个问题的一些讨论在这里.导致这个问题的原因并不明显(除非上面已经讨论了它的死亡符号链接),但看起来它cd /usr/local/Cellar/postgresql; cp -r 9.3.5 9.3.3可以让它brew link postgresql工作,尽管那是一个很好的问题.

如果您最近没有更新,请brew rm postgresql; brew update再试一次.你应该安装9.3.5.

(我不认为它在这里造成麻烦,但顺便说一下,不支持使用活动的Python virtualenv运行Homebrew.)
