看起来您有未定义的方法。我将在

重定向\u返回\u或中查找有问题的逻辑。调试仍在继续….
我相信重定向返回或方法是在app/helpers/sessions\u helper.rb中定义的
既然你还没有在上面列出代码，我就开始看了。
我接着看了这个项目的早期版本，就像edr所说的那样，这个方法重定向回或是在app/helpers/sessions\u helper.rb中定义的。
请检查它是否在那里，然后您的应用程序应该可以正常运行。如果您重新格式化代码，使其显示为此处的代码部分（每行前缀至少有4个空格），并从终端输出中删除所有ANSI终端代码（即，任何看起来类似“ANSI”的代码），则会更容易帮助您进行调试←[0m←[31m”）@Chrisbloom7对格式设置表示歉意。RSK非常感谢您重新设置了格式。您现在应该可以更轻松地解释代码了。您知道问题出在哪里吗？如果您成功调试了问题，请更新状态。
