在花了几个小时试图弄清楚它为什么不起作用之后,我终于设法安装了“pg”gem ......
最后我进入了sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config
它就像一个魅力。但是现在我在尝试 bundler 时仍然遇到同样的错误 - 所以我想我并没有真正解决问题?无论如何,这里bundle install
是说:

我认为问题在于捆绑器尝试使用来自另一个 postresql 安装(我已删除)的 pg_config 安装 gem。有什么方法可以确保捆绑器使用正确的路径?
