Capistrano的目标路径已经存在，不是一个空目录

Question

虽然在Ubuntu 14.04中部署与Capistrano的一个Rails应用程序，我收到以下错误：

fatal: destination path '/var/www/APP-NAME/repo' already exists and is not an empty directory. 


cf5a389e] Running /usr/bin/env [ -f /var/www/rd/repo/HEAD ] on LINODE-INSTANCE-IP

DEBUG[fc5f524b] fatal: destination path '/var/www/APP-NAME/repo' already exists and is not an empty directory. 

下面是配置文件：

• config/deploy/production.rb
• config/deploy.rb

的only reason这个错误我可以在网上找到;

same host in more than one role, so that they're racing? For example I mean that you might have the same IP address defined as an :app role host more than once.

我认为这不符合上述配置文件。

我有同样的问题。原因在于角色和/或服务器的双重定义。 尝试删除

server 'SERVER-IP', user: 'USERNAME', roles: %w{app} 

在production.rb

和

role :app, "SERVER-IP" 

在deploy.rb。后者似乎只是简单的语法，而前者是扩展的，所以实际上你可以两次声明角色（三次更精确：production.rb中的两个，deploy.rb中的一个）。希望能帮助到你。
