bundle失败 - 找不到PostgreSQL客户端库(libpq)

我想我已经尝试了所有关于这个问题的建议.仍然不适合我.

当我尝试捆绑...

$ bundle
...

Gem files will remain installed in
...
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.

以前代码的输出......

$ which bundle
/Users/Loren/.rvm/gems/ruby-2.1.1@global/bin/bundle

$ which gem
/Users/Loren/.rvm/rubies/ruby-2.1.1/bin/gem

$ which psql
/usr/local/bin/psql

我试图使用Homebrew卸载postgresql并重新安装,但没有帮助.

我试过了...

ARCHFLAGS="-arch x86_64" gem install pg

并且成功完成但是当我运行时bundle我仍然得到相同的错误.

我试过了 ...

gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config

那不起作用.

我试过了 ...

gem install pg -v '0.17.1' -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.2/bin/pg_config

那也不起作用.

我不知道还有什么可以尝试.谢谢你的帮助.
