Ruby 报错 aggregated_results: wrong number of arguments (given 1, expected 0)

在rails中，使用rake命令或者test命令中抛出了一个错误:

Finished in 0.316243s, 50.5940 runs/s, 88.5395 assertions/s.
.../.rvm/gems/[email protected]/gems/railties-5.0.2/lib/rails/test_unit/minitest_plugin.rb:9:in `aggregated_results': wrong number of arguments (given 1, expected 0) (ArgumentError)

这是一个bug，rails在这次更新中修复了它rails/rails#29022，但是因为种种原因，不想更新版本怎么办？

在Gemfile中加入这样一行:

gem "minitest", "5.10.1"

在对应的环境(test或者development)下，再执行bundle install即可解决。
