我已经开始了一个项目，我遇到了一个与bcrypt有关的大问题。
之前它完全正常（它甚至在以前版本的备份文件上打破）。
当我尝试创建新用户或登录时出现以下错误：
Processing by Devise::SessionsController#new as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"$$$==", "user"=>{"email"=>"percyjackson@example.com", "password"=>"[FILTERED]", "remember_me"=>"0"}, "commit"=>"Log in"}
Completed 401 Unauthorized in 96ms (ActiveRecord: 0.0ms)

我的gemfile中的gem说
gem'bcrypt-ruby'，'〜＆gt; 3.0.0'
我几乎尝试了各种变化。
