我以前从未见过这个错误，我不知道我应该找什么。

/opt/local/bin/rake:19首先，我认为这可能是我的迁移中的某个错误，所以我将它们全部删除以检查，错误仍然存在。奇怪的是，应用程序/控制台启动时没有任何问题：
$ rails server
=> Booting Mongrel
=> Rails 3.0.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server然后我就不知道去哪里找错误了。有什么帮助吗？

好吧，我尝试了所有方法，
rake db:reset，删除所有迁移，等等...问题是一个gem.
scrubyt gem在我的 gemfile 造成了所有这些麻烦...20jt8wwn2#
我在Ubuntu 20.04上开发Rails 4应用程序时遇到了类似的挑战。
当我运行
rake:db migrate命令时，我得到以下错误：rake aborted！SystemStackError：堆栈级别太深/home/mycomputer/Projects/my-project/config/environment.rb：5：in

经过调试，我认为这个问题是由一些过时的gem引起的，它们导致了一些依赖性问题。
我所做的就是使用以下命令将gems更新到与项目兼容的版本：
你也可以注解掉gem，然后尝试在取消注解后一个接一个地安装它们。如果你足够幸运地追踪到导致问题的gem，那么你可以只使用
另一种方法，虽然不可取（因为您可能会遇到一些依赖兼容性问题），但将删除您的
Gemfile.lock文件，然后使用以下命令重新安装您的gems：或者：

有时数据库会出错。你可以做的是保存你当前的模式，然后重置你的数据库
rake db:reset，并进行一次新的迁移script/generate migration add_old_db，将你的整个旧模式作为新的迁移。只需将你的旧模式复制并粘贴到新的迁移中，它就会像以前一样生成新的表。当然，你的数据会在这个过程中被破坏。
