在 rvm 下使用 postgres.app 要求 pg 时出错 [英] Error requiring pg under rvm with postgres.app

问题描述

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...
Successfully installed pg-0.15.1

Rammy:~ phrogz$ ruby -v -e "require 'pg'"

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.
