用Capistrano部署的问题（符号链接错误）

当试图部署到我的登台服务器时，当Capistrano试图创建database.yml文件时，我看到一个错误。用Capistrano部署的问题（符号链接错误）

目前我在我的gitIgnore文件中有database.yml文件（我曾试过包括它）。

我从来没有遇到过这个问题，所以我没有真正知道如何去调试这个问题。

任何帮助深表感谢。

看起来你正在使用一些自定义Capistrano的食谱处理database.yml的，请把它们 – cthulhu 2013-02-19 17:41:39

只是加了我deploy.rb的内容文件，希望它有帮助。 – 2013-02-19 17:45:14

它看起来像你的答案就在你的眼前。

** [out :: example.com] ln: creating symbolic link `/home/deploy/example.com/releases/20130219164028/config/database.yml' 
** [out :: example.com] : File exists

修改您的部署：copy_database_yml先删除符号链接，或者只有当它不存在，创建它。顺便说一句，这个任务的作用远不止它的名字，这是不好的。

这似乎是创建符号链接时的Capistrano问题。

试评在deploy.rb文件中的角色：
