错误安装PostgreSQL的Mac OS X Lion的

我用RVM安装Ruby和Rails，现在正尝试通过错误安装PostgreSQL的Mac OS X Lion的

Sudo Gem install pg

我的所有其他宝石来安装PostgreSQL似乎安装罚款。这可能是因为我卸载并重新安装RVM

不过，我得到以下错误

尝试：gem install postgres – Luke 2012-01-03 20:46:18

我试过了。我刚刚得到它的工作。我必须做brew卸载postgresql，然后brew安装postgresql – 2012-01-03 20:54:56

注意OS X 10.7上的那些人：postgres现在默认安装。在cli上输入psql。当然，你仍然需要宝石。 – Rimian 2012-01-16 21:42:27
