在将Heroku应用程序从Bamboo迁移到Cedar时，我得到了这个意想不到的错误:
app[web.1]: Exiting

heroku[web.1]: State changed from starting to crashed
最重要的一行:
/app/供应商/包/ruby/rails 2.0.0/珠宝/railties-3.0.19/lib//架/log_tailer。rb:8:in ' size': No such file or directory - log/production.log (Errno:: enent)
- 我的源代码中没有
production.log。 - 我的
config/environments/production.rb说config.logger = Logger.new(STDOUT)。 - 我在源代码的几十个地方使用
logger.debug。
Heroku甚至不允许写入文件系统，所以我不知道这是从哪里来的。
知道我该怎么修吗?
我从文件config/environments/production.rb中删除了config.logger = Logger.new(STDOUT)行，这就解决了问题。
