当我尝试运行 bundle (捆绑安装)时,我总是得到

Installing pg (0.13.2) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/ryan/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.13.2 for inspection.
Results logged to /Users/ryan/.rvm/gems/ruby-1.9.2-p290/gems/pg-0.13.2/ext/gem_make.out
An error occured while installing pg (0.13.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.13.2'` succeeds before bundling.

我使用Mac OS X 10.6,安装的PostgreSQL版本是9.1。我发现问题出在 libpq-dev 中,我该如何安装/修复它?

最佳答案

如果您在 Linux 上运行,您可能会对对我有用的内容感兴趣:

sudo apt-get install postgresql
sudo apt-get install libpq-dev

然后

gem install pg

然后

bundle install
