在部署到Heroku时，我收到了两个项目的启动错误。两者都在本地运作良好，似乎sidekiq的工人启动会给乘客带来问题。我真的不明白问题的来源，并检查了我的procfile，我的sidekiq conf和其他元素。任何意见都会非常感激。

我在1小时前遇到了同样的问题。

似乎heroku-deflater在21小时前更新过。 虽然我不知道造成这个错误的原因， 通过在Gemfile上定义heroku-deflater版本，我能够在Heroku上使我的应用程序运行良好。
■Gemfile
gem＆＃39; heroku-deflater＆＃39;，＆＃39; 0.5.3＆＃39;，：group =＆gt; ：生产
我想等待heroku-deflater再次更新。
谢谢！
