安装到virtualenv中?MacBook Pro with OS X 10.6?
当我运行pip install psycopg2从我的virtualenv,我收到如下所示的错误。
我试图连接到使用Django的服务器上的遗留数据库,我不想在我的开发系统上安装Postgresql如果可能的话。
为什么不安装Postgresql?
我收到一个错误,当使用homebrew安装Postgresql。我有Xcode4,只有Xcode4安装在我的MacBook Pro,我认为它与缺少gcc 4.0相关。但是,这是另一个StackOverflow问题的问题。
更新2011年4月12日上午8:37:我仍然想知道如果这是可能的,而不是在我的MacBook Pro上安装Postgresql。但是,我运行brew更新和强制重新安装ossp-uuid与brew install –force ossp-uuid和现在brew安装postgresql工作。与Postgresql成功安装,我能够安装psycopg2从我的virtualenv。
