我正在尝试使用命令：
将非主分支部署到herokugit push heroku staging:master
但发生以下错误。使用master分支，一切正常。

production.rb第85行：
config.logger = Logger.new(Rails.root.join("log",Rails.env + ".log"), 5, 100*1024*1024)
更新
嗯，问题出在第85行，但我不知道为什么
有人对此有一些建议吗？提前致谢
答案 0 :(得分：4)
听起来已经从git存储库中删除了log目录。也许在你的新分支上，你有git rm的所有内容？ Git会自动删除任何没有任何文件的目录，因此通常人们会使用.keep或.gitkeep文件来保持log之类的内容不会完全消失。
另外，您应该确保.gitignore不是这个：
/log
但是这个：
/log/*.log
