I (mistakenly) updated Rspec to version 2.4, but my Gemfile is on version 2.3. I m now getting the following error message when I try to run Rspec. I believe I need to revert to 2.3 -- any idea how I can do this?
/Users/woshea/.rvm/gems/ruby-1.9.2-p136@global/gems/bundler-1.0.7/lib/bundler/runtime.rb:27:in `block in setup : You have already activated rspec-core 2.4.0, but your Gemfile requires rspec-core 2.3.1. Consider using bundle exec. (Gem::LoadError)
两种选择:
gem install, and it should work.bundle exec rspec instead of just rpsec and that ll make sure it uses the bundled version.You can launch your spec only by bundler
bundle exec rspec spec
或
bundle exec rake spec
