git://github.com/reactjs/react-rails.git (at master) is not yet checked out. Run `bundle install` first.
根據https://github.com/bundler/bundler/blob/master/ISSUES.md,解決方是執行以下程式碼,重新安裝 dependencies :
# remove user-specific gems and git repos
rm -rf ~/.bundle/ ~/.gem/bundler/ ~/.gems/cache/bundler/
# remove system-wide git repos and git checkouts
rm -rf $GEM_HOME/bundler/ $GEM_HOME/cache/bundler/
# remove project-specific settings
rm -rf .bundle/
# remove project-specific cached gems and repos
rm -rf vendor/cache/
# remove the saved resolve of the Gemfile
rm -rf Gemfile.lock
# uninstall the rubygems-bundler and open_gem gems
rvm gemset use global # if using rvm
gem uninstall rubygems-bundler open_gem
# try to install one more time
bundle install
