我尝试使用/Applications/Postgress.app/Contents/更改文件夹sudo chmod -R 777的权限无效。

不幸的是，这对Mac无效。在这里，我分享了现在实际的个人经历，它只是有效。

第一步。安装Homebrew。这是“OS X缺少的软件包管理器”。如所声称的那样，您只能使用一个命令来执行此操作：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

它会询问您的密码一次，但是您可以非常轻松地管理更多的软件包。安装Homebrew后，运行brew doctor以检查系统并按照说明操作。如果你有全新的Mac，它可能会要求你安装XCode和构建工具。

下一步。安装PostgreSQL。

就像brew install postgres一样简单。这需要一段时间来下载PostgreSQL及其依赖项。如果您需要比最新版本更早的确切版本，请使用brew search postgres找到您需要的版本。

最后。安装pq gem。

这里没有诀窍：

gem install pg

干杯。
