我在 OS X (10.8.3) 上使用 Postgres.app.我已经修改了我的 PATH，以便应用程序的 bin 文件夹位于所有其他文件夹之前.

I'm using Postgres.app on OS X (10.8.3). I have modified my PATH so that the bin folder for the app is before all others.

Rammy:~ phrogz$ which pg_config /Applications/Postgres.app/Contents/MacOS/bin/pg_config

我已经安装了 rvm 并且可以毫无错误地安装 pg gem，但是当我需要它时，我收到一个错误:

I have rvm installed and can install the pg gem without error, but when I go to require it I get an error:

Rammy:~ phrogz$ gem -v 1.8.25 Rammy:~ phrogz$ gem install pg Fetching: pg-0.15.1.gem (100%) Building native extensions. This could take a while...

我需要做什么才能正确安装 pg gem?

What do I need to do to get the pg gem properly installed?

推荐答案

这对我有用:

sudo env ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/Applications/Postgres93.app/Contents/MacOS/bin/pg_config

只需仔细检查/Applications/Postgres93.app.. 路径是否存在.

Just double check that the /Applications/Postgres93.app.. path exists for you.
