由于网络超时，似乎部署无法完成，我不得不按CTRL + C进行回滚。现在，当我尝试再次部署时，它会给出以下错误。
我不确定为什么会发生这种情况，因为在本地或服务器上没有更改/编辑任何内容。看起来Capistrano的某些设置已损坏/你能建议我有什么选择来解决这个问题吗？
deploy.rb文件看起来很好，因为我已经使用它直到所有部署。任何时候都没有问题。

编辑 - 第二条评论链接psych.rb error when deploying with Capistrano 'mapping not allowed in this context'解决了这个问题。有2个清单json文件，我删除了两个，现在已经部署了。
