Question

我无法在Heroku上查看正在运行的应用程序。我收到了标准Application Error屏幕 -

应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。

Heroku Logs：

我的proc文件目前包含： web: bundle exec rackup config.ru -p $PORT -E $RACK_ENV

我将其更改为以下内容以查看会发生什么，并且应用程序错误仍然存在： web: bundle exec rails server -p $PORT

我认为问题在于它没有获得正确的端口，但我无法在SO上找到适合的解决方案。

当我运行heroku run rails console时，我会收到以下日志：

更新（上午7:17）：我在Heroku上尝试了Restarting all Dynos，但它没有用。

Fixnum＆amp; Bignum现已弃用＆amp;应该使用Integer来代替Ruby 2.4。我也发现您使用的rails 4.2.5与Ruby 2.4不兼容。

您需要将rails版本升级到至少Rails 4.2.8。
