【中文标题】NoMethodError: nil:NilClass / \'additional_paths\' [capistrano+webpacker] 的未定义方法“+”【英文标题】:NoMethodError: undefined method `+' for nil:NilClass / 'additional_paths' [capistrano+webpacker]NoMethodError: nil:NilClass / 'additional_paths' [capistrano+webpacker] 的未定义方法“+” 【发布时间】:2020-10-07 22:43:41 【问题描述】:我必须将我的 rails 版本从 5 更新到 6,在此之前一切正常。
问题只发生在 capistrano 上...当我运行 rake assets:precompile
时,即使使用新版本也一切正常。
这是错误:

谁能帮我解决这个问题?
【问题讨论】:
【参考方案1】:在您的 config/webpacker.yml 中,resolved_paths
已被弃用,应替换为 additional_paths
(https://github.com/rails/webpacker/commit/0adb3dc342addaa00122f9b022bf05606225c39c#diff-04c6e90faac2675aa89e2176d2eec7d8R365)
我希望这会有所帮助,我遇到了同样的问题,这解决了我的问题。
