我将文件“ GemFile”更改为5.0.2并给出了错误。该错误并不表示任何gem不支持5.0.2。请帮帮我。 更新原因如下：

我尝试了许多方法来解决此问题，但没有任何帮助。有没有人遇到过类似的情况，并且知道解决此问题的方法。

啊，ol's Rails主要版本的凹凸任务。
看起来您的许多宝石都在Gemfile中设置了特定的版本。仅仅更改rails gem版本并不能解决问题，您会遇到很多依赖关系错误，更糟糕的是，这仅仅是开始-以后很多其他情况可能会变糟。
您可以从所有gem中删除版本，然后将rails设置为5.2或任何其他值，然后在它们弹出时逐步解决依赖项错误。期望这是一个漫长的过程，并且显然不要在生产机器上这样做。
在某些情况下，甚至可能需要或发现将更新应用于基础服务（例如数据库）更方便。
如果您没有任何规格/测试，则需要测试整个应用程序，或开始编写它们。

在Gemfile中进行更改后，您是否运行过bundle install？并且不建议直接升级到Rails 5.2。首先使其稳定并在Rails 5.0中运行，然后在5.1中运行
