Mongoid and Rspec error Mongo::Error::NoServerAvailable:

Question

当我开始 Rspec 测试时，出现此错误：

  1) User checks if the user is created
     Failure/Error: expect{ @user_test = create(:user) }.to change { User.count }

     Mongo::Error::NoServerAvailable:
       No server is available matching preference: #<Mongo::ServerSelector::Primary:0x70316515164800 tag_sets=[] max_staleness=nil> using server_selection_timeout=30 and local_threshold=0.015

Finished in 30.14 seconds (files took 8.39 seconds to load)
1 example, 1 failure

Failed examples:

rspec ./spec/models/user_spec.rb:10 # User checks if the user is created

我真的很困惑。

我的 mongo 服务器也是运行。

我的user_spec.rb：

require 'spec_helper'
require 'rails_helper'
require 'database_cleaner'


DatabaseCleaner.strategy = :truncation

RSpec.describe User, :type => :model do

  it "checks if the user is created" do
    expect{ @user_test = create(:user) }.to change { User.count }
  end

end

知道为什么我的 mongo 不起作用吗？

我的配置文件有误，所以我将其更改为：

测试：客户：默认：数据库：测试主持人： - 127.0.0.1:27017 选项：读：模式：：主要 max_pool_size: 1 log_level: :调试
