Capistrano错误：未定义的方法`已经在<rake ::任务加载：defaults => [：>]：：Rake ::任务

Question

我花了太多的时间调试这个，我不知道发生了什么。 “帽子生产部署”今天早上运行良好，现在它只是抛出一个错误。令人惊讶的是，谷歌迄今为止没有得到太多的帮助。我知道的代码基地没有什么改变：

有人能提供一些方向吗？

Answer 1

是的，它看起来像你在新发布的Capistrano 3.6.0中发现了一个错误。请在此处报告此问题：https://github.com/capistrano/capistrano/issues

潜在问题是Capistrano 3.6.0（与错误地）与Rake < 11.0.0不兼容。

在此期间，您可以通过升级耙11.0.0或更高版本与gem install rake或bundle update rake解决此问题（根据您是否使用bundle exec对Capistrano的或没有）。

如果您无法升级Rake，请将Capistrano降级到版本3.5.0，直到修复该错误。

更新：Capistrano 3.6.1已发布并恢复与Rake < 11.0.0的兼容性。
