Question

UGH ......我在OS X Yosemite下破坏了我（以前运行的）Rails设置。我使用Homebrew更新了我的Git版本。在将Git放到我想要的位置之后，运行'rails c'会出现以下错误：

/Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg.rb:4:in `require': dlopen(/Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg_ext.bundle, 9): Library not loaded: /usr/local/lib/libpq.5.6.dylib (LoadError)
  Referenced from: /Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg_ext.bundle
  Reason: image not found - /Users/grogers/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/pg-0.16.0/lib/pg_ext.bundle

看到对pg_ext的引用，我试图验证我的postgresql安装的部分。如果我尝试'gem install pg'或尝试使用bundler更新gem，我会得到这个：

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

    /Users/grogers/.rbenv/versions/2.0.0-p353/bin/ruby extconf.rb
checking for pg_config... yes
Using config values from /usr/local/bin/pg_config
*** 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.

我可能会让我的问题变得更糟，但我回过头来重新制作'brew install postgres'，但仍然会遇到同样的错误。

任何帮助表示赞赏。谢谢！

您是否也通过Homebrew升级Postgresql？如果没有，你运行的是什么版本的Postgres，以及如何安装它？

如果您升级了Postgres，则需要重建pg gem的原生绑定：gem uninstall pg && gem install pg。

破碎的Rails设置/ pg gem
