@iFurniture，问题在这里，你的＆＃39; fallback_to_404＆＃39;设置为true， 所以你总是得到error_404
def find_page(fallback_to_404 = true)
@page ||= ...
@page || (error_404 if fallback_to_404)
end
我建议你这样做：
def find_page(fallback_to_404: false)
error_404 if fallback_to_404
@page ||= ...
@page || (error_404 if fallback_to_404)
end
因此默认情况下fallback_to_404将为false，如果您想将其设置为true，请将其称为
find_page(fallback_to_404: true)
关于这个：
@page || (error_404 if fallback_to_404)
你可能想要吗？
fallback_to_404 ? error_404 : @page
看起来更好。

我会检查你的before_action :error_404, :unless => :current_user_can_view_page?或许暂时删除该代码以查看它是否可以加载，如果有，那么很可能该方法设置不正确。

我可以解决运行CMD的问题
bundle exec rake db:seed
感谢您的帮助。
