伙计们得到这个错误任何线索，rubygems.org已经启动，当我下载单个gem时，它确实如此。
bundle install
Fetching gem metadata from https://rubygems.org/........
Fetching gem metadata from https://rubygems.org/..
Using rake (0.9.2)
Net::HTTPServerException: 403 "Forbidden"
An error occurred while installing i18n (0.6.1), and Bundler cannot continue.
Make sure that `gem install i18n -v '0.6.1'` succeeds before bundling.
有任何线索吗？
