Based on this post's answerand it worked for me (Yosemite OSX 10.10), you can try the following:
根据这篇文章的答案并且它对我有用（Yosemite OSX 10.10），您可以尝试以下操作：
$ sudo su
$ env ARCHFLAGS="-arch x86_64" gem install pg
You don't have to reinstall pg from homebrew.
您不必从自制软件重新安装 pg。

I uninstalled postgresql using home-brew ( I had used it to install postgresql before )
我使用 home-brew 卸载了 postgresql（我之前用它来安装 postgresql）
I installed the Postgres.app and this updated my PATH
我安装了 Postgres.app，这更新了我的 PATH
I then had to stop the currently running postgresql db

I then was able to launch the Postgres.app and it started on port 5432
然后我就可以启动 Postgres.app 并在端口 5432 上启动
I then had to restart my terminal
然后我不得不重新启动我的终端
Then I was able to run bundle and it worked.
然后我能够运行 bundle 并且它起作用了。

For ease of management and upgrading, etc. I have used the (PostgreSQL Applicationon my Mac with the following gem install (same as yours above).
为了便于管理和升级等，我在我的 Mac 上使用了 ( PostgreSQL 应用程序，并安装了以下 gem (与上面的相同)。
gem install pg -- --with-pg-config=/Applications/Postgres__version__.app/Contents/MacOS/bin/pg_config
gem install pg -- --with-pg-config=/Applications/Postgres__version__.app/Contents/MacOS/bin/pg_config
I have had no issues with this approach (versus a custom install or via Homebrew from which I have had a few problems).
我对这种方法没有任何问题（与自定义安装或通过 Homebrew 相比，我遇到了一些问题）。

In my particular instance I was trying to run bundle installon my first heroku app. I did all the items that @boobooninja listed (with slightly different paths, of course). What ended up working for me was a combination of two answers. I needed to
在我的特定实例中，我试图bundle install在我的第一个 heroku 应用程序上运行。我做了@boobooninja 列出的所有项目（当然，路径略有不同）。最终对我有用的是两个答案的组合。我需要
$ sudo su
$ env ARCHFLAGS="-arch x86_64" gem install pg -v '0.17.1'
By adding the -v 0.17.1and specifying the version needed by heroku I was able to complete my bundle and proceed.
通过添加-v 0.17.1并指定 heroku 所需的版本，我能够完成我的包并继续。

Please make sure that you have the 'libpq-dev' package installed on your system
请确保您的系统上安装了“libpq-dev”软件包
So try installing libpq-dev:
所以尝试安装 libpq-dev：
for Ubuntu systems: sudo apt-get install libpq-dev
on RHEL systems: yum install postgresql-devel
for Mac: brew install postgresql
Then install pg gem
然后安装 pg gem
$ gem install pg -v '0.17.1'
$ bundle
回答by Gray Kemmey
If you want to still be able to add gem 'pg'to your gemfile and use bundle install, and you know PostgreSQL and libpq-dev are installed (which I believe both should be since OS X ships with PostgreSQL) you need only tell your $PATHwhere to find pg_config. Try this:
如果您仍然希望能够添加gem 'pg'到您的 gemfile 并使用bundle install，并且您知道 PostgreSQL 和 libpq-dev 已安装（我相信这两者都应该是因为 OS X 附带 PostgreSQL），您只需要告诉您$PATH在哪里可以找到pg_config. 试试这个：
$ ln -s /Library/PostgreSQL/9.1/bin/pg_config /usr/local/bin/pg_config
$ ln -s /Library/PostgreSQL/9.1/bin/pg_config /usr/local/bin/pg_config
Make sure to replace 9.1with whatever PostgreSQL version you have installed. And make sure wherever you're creating the link is in your $PATH. Once that's done, run bundle installto install the pggem.
确保替换9.1为您安装的任何 PostgreSQL 版本。并确保您创建链接的任何位置都在您的$PATH. 完成后，运行bundle install以安装pggem。

For me, the trick was to re-link Postgres 9.3.0
对我来说，诀窍是重新链接 Postgres 9.3.0
brew link postgresql
