ruby-on-rails - rake db:migrate rake 中止！无方法者

问题描述

当我尝试运行rake db:migrate时，出现以下错误：

DEPRECATION WARNING: The factory_girl gem is deprecated. Please upgrade to factory_bot. See https://github.com/thoughtbot/factory_bot/blob/v4.9.0/UPGRADE_FROM_FACTORY_GIRL.md for further instructions. (called from <top (required)> at /var/www/html/sophy_web/config/application.rb:14)

(See full trace by running task with --trace)

我正在使用 ruby​​ 版本 2.5.1 和 rails 4.2.8。

我的 rollbar.rb 的代码：

require 'rollbar/rails'
Rollbar.configure do |config|      
  config.access_token = '9234902384023843203fsd23'

  # Here we'll disable in 'test':
  if Rails.env.test?
    config.enabled = false
  end
end

我的环境代码.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Rails.application.initialize!
