ruby-on-rails - NameError（未初始化的常量 BCrypt）

Question

当我尝试创建密码时，我在 Rails 控制台中不断收到此错误。

BCrypt::Password.create("foobar")

NameError (uninitialized constant BCrypt)

我的宝石文件：

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.6.1'


# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

我的用户模型：

class User < ApplicationRecord
    has_secure_password
    belongs_to :school
    has_many :user_courses
    has_many :courses, through: :user_courses  
    has_many :user_resources
    has_many :resources, through: :user_resources
  end

我的用户架构：

  create_table "users", force: :cascade do |t|
    t.string "name"
    t.string "category"
    t.integer "school_id"
    t.boolean "permission", default: true
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

任何想法为什么会发生此错误？我也尝试在我的用户模型中要求 bcrypt 但仍然没有运气。我也尝试了 Password.new 但仍然没有。不知道此时还能做什么，任何帮助将不胜感激！
