debian wheezy
ruby2.4.0（也尝试与ruby2.2.0）
# I also installed rspec and rspec-core with : gem install rspec gem install rspec-core 执行“bundle env”给出：
Bundler 1.14.4 Rubygems 2.6.10 Ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux] GEM_HOME /usr/local/rvm/gems/ruby-2.4.0 GEM_PATH /usr/local/rvm/gems/ruby-2.4.0:/usr/local/rvm/gems/ruby-2.4.0@global RVM 1.29.0 (latest) Git 1.7.10.4 Platform x86_64-linux rubygems-bundler (1.4.4)
当我执行以下命令时：bundle exec rake -t
我有以下错误日志：
rake aborted!

当我走到testing的第一线时，我看到：
unless Rails.env.production? require 'rspec/core' require 'rspec/core/rake_task' require 'rspec/core/formatters/json_formatter'
错误在第3行：
require 'rspec/core'
