无法在Ubuntu 12.10(AMD64)上安装gem“pg”

我一直(不成功)尝试在我的ruby 1.9.3-p286上安装“pg”gem,但似乎没有任何效果。

我已经安装了postgresql(9.1),libpq-dev和其他一些像postgresql-server-dev-9.1。我试图将“with-pg-config”标志传递给gem install,但似乎没有任何效果。

每次我尝试安装gem时,都会输出如下内容:

ERROR:  Error installing pg:

我做错了什么?在尝试安装gem之前,我还应该做些什么吗?

提前谢谢。

好的,所以joelparkerhenderson的回答让我觉得路径和图书馆可能有问题,而且还在继续挖掘......

我发现了this很棒的帖子,它解决了!基本上问题在于RVM。所以,我的问题已经解决,对于那些可能遭受同样事情的人,请点击链接!

您的错误似乎缺少libpq-dev

您是否要先在系统上安装Postgres?

试试这个:

sudo apt-get install postgresql postgresql-client postgresql-server-dev-all libpq-dev

接下来,你能够以root身份安装pg gem吗?

sudo su - root
gem install pg
