更新到优胜美地10.10后，我无法连接到我的postgresql数据库。我运行rails控制台并尝试获取第一个用户，但遇到此错误...

After updating to Yosemite 10.10 I cannot connect to my postgresql database. I run the rails console and try and get the first user but get this error...

我该怎么办！我试图重新安装postgresql，重新安装自制软件。

What do I do! I have tried to reinstall postgresql, reinstall homebrew. Please help!

推荐答案

最好通过安装 http://postgresapp.com/ 应用！我在10.9.4中也遇到了同样的问题。同样使用10.10。

You are better off using the easy method by installing the http://postgresapp.com/ app! I too had this same issue with 10.9.4. Also with 10.10.

brew install postgres 在进行任何OS X升级时都会出现问题，因此请避免使用。因此，请安装该应用，然后：

brew install postgres will give issues when doing any OS X upgrades so avoid it. So install the app then:

如果无法立即进行安装，请将其添加到您的个人资料中。对我来说，我不必在个人资料中添加以下内容：

Add this to your profile if the install do not work out of the box. For me I never had to add the below in my profile:

export PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"

此行必须位于个人资料的顶部：

This line must be at the top of your profile:

export PATH=/usr/local/bin:$PATH

祝你好运！
