Question

我在小牛队中安装了postrgres应用程序。它在5432端口上运行。

我有一个使用pg gem的rails项目。

然而，当运行＆＃34;捆绑安装＆＃34;我收到这个错误：

    Installing pg (0.17.1) 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /Users/jonathanhurley/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb

No pg_config... trying anyway. If building fails, please try again with

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.

    --with-pg-lib
    --without-pg-lib=${pg-dir}/


Gem files will remain installed in /Users/jonathanhurley/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.17.1 for inspection.
Results logged to /Users/jonathanhurley/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.17.1/ext/gem_make.out

An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

如果没有安装postgres但我确实理解了这个错误。

我建议首先安装Homebrew，因为它是OS X的一个很好的包管理器。您可以使用以下命令安装它：

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

安装完homebrew后，可以使用brew命令安装postgresql。

brew install postgresql

我的同事遇到了与昨天相同的问题，但在使用自制软件再次安装后，它按预期工作。

在osx mavericks上安装postgres
