Git error: command `git clone 'git://github.com/37signals/mail_view.git' "/home/adolph/ruby-china/vendor/bundle/ruby/1.9.1/cache/bundler/git/mail_view-55dbcc2547e571889146c4ef1770f86672ca2598" --bare --no-hardlinks` in directory /home/adolph/ruby-china has failed.

================================================ 我用的命令是

$ cd ruby-china
$ bundle install --path vendor/bundle
##用$ bundle install是同样的错误

=============================================== 我的操作系统是 ubuntu 10.10，ruby 1.9.2 安装者也成功
