ruby-on-rails - 使用 Ubuntu 的 pg gem

Question

我正在尝试使用新的 rails 应用程序安装 pg gem，但我一直收到相同的错误:

Building native extensions.  This could take a while...
ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

        /home/arthur/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb --with-pg-lib=/usr/lib
checking for pg_config... yes

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

我已经尝试了这个问题的所有内容: How to install PostgreSQL's pg gem on Ubuntu?
但没有什么对我有用。

顺便说一下，那是 ruby​​ 1.9.2 和 Rails 3.2。

谢谢

安装 postgresql 9，然后安装您的 gem。

sudo apt-get install postgresql libpq-dev

现在，运行

gem install pg

进而

捆绑安装
