使用capistrano部署到暂存的Rails将生成以下错误

Question

当我尝试使用本地机器(MAC) {Rails app}中的capistrano gem部署到服务器时，我得到了以下信息。我对rails很陌生

user-mbp:xp user$ cap staging deploy

我试过git:check，但仍然显示相同的效果。

有两种可能的解决方案

1. 将您的私钥复制到您的部署机器上，因为您可以将私钥推送到Github (据我所知)，您的开发机器上有一个私钥，Github上有相应的公钥。您可以将私钥复制到部署机器上以消除错误。 开发-机器$ scp ~/..ssh/id-rsa.PUB部署-机器:键

然后将ssh放到您的部署机器上，然后执行

deployment-machine$ mv ~/.ssh/id-rsa.pub ~/.ssh/id-rsa.old
deployment-machine$ mv ~/key ~/.ssh/id-rsa.pub

1. 在您的部署机器上创建一个密钥，并将公钥添加到Github中，在Github帮助中可以很容易地理解如何这样做

希望这能有所帮助。
