You should have postgresql installed before you install pg gem.
在安装 pg gem 之前，您应该安装 postgresql。
sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update
sudo apt-get install postgresql libpq-dev
If your sqlite is not working, it looks like there are some packages you might have missed.
如果您的 sqlite 不工作，看起来您可能错过了一些软件包。
sudo apt-get install libreadline-dev libssl-dev zlib1g-dev build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev

On Ubuntu 14.04 (and possibly every other Debian 7 based distro) this problem is caused by the absence of the Ruby development package. Thus the fix is simply to install it:
在 Ubuntu 14.04（可能还有其他所有基于 Debian 7 的发行版）上，这个问题是由于缺少 Ruby 开发包造成的。因此，修复只是安装它：
sudo apt-get install ruby1.9.1-dev

I had an issue with slightly different Ruby builds. The existing application's Gemfile.lockwas created using ruby-1.9.3-p194and my local ruby was ruby-1.9.3-p484. Switching to the proper ruby allowed for a successful bundle.
我遇到了稍微不同的 Ruby 构建的问题。现有的应用程序Gemfile.lock是使用创建的ruby-1.9.3-p194，我的本地 ruby 是ruby-1.9.3-p484. 切换到正确的 ruby 可以成功捆绑。

On Debian, the pginstall was failing to build native extensions because postgres wasn't installed.
在 Debian 上，pg由于未安装 postgres ，安装无法构建本机扩展。
I installed the postgres dependencies with:
我安装了 postgres 依赖项：
$ apt-get install postgresql postgresql-client libpq-dev
Then the pggem built its dependencies just fine:
然后pggem 很好地构建了它的依赖项：
$ gem install pg -v '0.18.3'
Building native extensions. This could take a while...
Successfully installed pg-0.18.3
1 gem installed
