我嘗試使用sudo chmod -R 777將文件夾/Applications/Postgress.app/Contents/的權限更改為無效。

不幸的是，這不適用於Mac。 在這里，我分享了當今的真實個人經驗，並且確實有效。

第一步。 安裝Homebrew 。 這是“ OS X缺少的程序包管理器”。 如所聲明的，您只能使用一個命令來執行此操作：

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

它將詢問您一次密碼，但是之后您可以非常輕松地管理更多軟件包。 安裝Homebrew后，請運行brew doctor檢查系統並按照說明進行操作。 如果您使用的是全新的Mac，它可能會要求您安裝XCode和構建工具。

下一個。 安裝PostgreSQL。

它與brew install postgres一樣簡單。 下載PostgreSQL及其依賴項將需要一些時間。 如果您需要比最新版本更舊的確切版本，請使用brew search postgres准確找到所需的版本。

最后。 安裝pq gem。

這里沒有技巧：

gem install pg

干杯。
