Heroku 上缺少配置目录 - config.ru 中的 LoadError

Question

更新
我现在知道（通过运行heroku run bash 和ls -la）在部署到heroku 后确实缺少config 目录。但是，它存在于本地存储库中。

---

.gitignore

/.bundle

# Ignore the default SQLite database.
/db/*.sqlite3

# Ignore all logfiles and tempfiles.
/log/*.log
*.log
/tmp

将我的应用程序推送到 heroku 后，我收到 /app/config/environment 的 LoadError，这在以前的版本中没有发生过。 未对 config.ru 进行任何更改。 文件config/environment.rb 存在。

我尝试了回滚，但因为之前的版本有不同的附加组件而无法回滚。

我该如何解决这个错误？

我已就我的应用程序的类似问题联系 heroku，我们发现删除文件 .gitignore 旁边的文件 .slugignore 解决了问题。

在你身边可能是同样的情况，你可以在这里看到我的问题： why config folder is not pushed?

看看我对我的问题的回答。

我希望这会有所帮助

使用发布管理http://blog.heroku.com/archives/2010/11/17/releases/，每次添加或删除配置变量时，它都会创建一个新版本，因此即使您有不同的附加组件集，您也应该能够回滚到以前的版本。

你的 Procfile 中有什么？尝试像这样指定RACK_ENV：

web: bundle exec thin start -p $PORT -e $RACK_ENV

当您运行git push heroku master 时，一切似乎都正常吗？
