【问题描述】：

我尝试安装 Django-toolbelt，但我不断收到以下内容。我正在使用 Mac。我试过用谷歌搜索解决方案，但没有运气。谢谢。

【问题讨论】：

pg_config 是 PostgreSQL 附带的 PostgreSQL 开发库配置脚本。安装 PostgreSQL，例如来自 Homebrew。

Can't install psycopg2 with pip in virtualenv on Mac OS X 10.7 的可能重复项

@MikkoOhtamaa 解决了它！谢谢！

【参考方案1】：

我收到了完全相同的错误消息。但是，就我而言，我已经安装了 psycopg2。发生的事情如下：

我必须先安装 Macports， 然后在python文档中我得到了这一行：

sudo port install py27-psycopg2

但是那一行在

中安装了包

'/opt/local/Library/Frameworks/Python.Framework/....'

而不是

'/Library/Frameworks/Python.Framework/....'

我刚刚创建了一个符号链接来解决问题。
