Rails – ruby / 2.1.0 / minitest / parallel_each.rb：67：in”：类’Minitest :: Unit’的未定义方法’_run_suites’（NameError）
我克隆了这个存储库： https ： //github.com/railstutorial/sample_app_rails_4
我按照说明在我的本地机器中设置项目：
cd /tmp git clone https://github.com/railstutorial/sample_app_rails_4.git cd sample_app_rails_4 cp config/database.yml.example config/database.yml bundle install --without production bundle exec rake db:migrate bundle exec rake db:test:prepare bundle exec rspec spec/ 但是当我运行“bundle exec rspec spec”进行测试时，我得到了这个输出：

我的电脑：Ubuntu（14.04）我的rails版本是：4.0.8我的ruby版本是：ruby 2.1.3p242（2014-09-19修订版45877）[x86_64-linux-gnu]
我在谷歌上找不到多少帮助，我真的很难解决这个问题
一个有用的信息，当我使用nitrous.io并在那里设置项目一切正常，可能是我的电脑出了问题？
