Question

我的任务是在前一天升级机器上的ruby安装。我从源代码安装（通常是./configure,make,make install）并更新了所有宝石。目前，该网站不会加载Ruby Rack错误，我不知道如何解决：

你们之前有没有见过这种类型的错误？有关如何解决它的任何想法？

Answer 1

我发现了我的问题。查看错误时，我注意到跟踪中的第一个模块是rack-flash。事实证明它的新版本与此应用程序也在使用的sinatra不兼容。我注释掉了闪存相关的代码并运行了应用程序。

现在我只需要找出将闪存相关代码移植到sinatra-flash的正确方法，我想我很高兴。

Ruby Passenger不会开始
