所以我克隆了 jekyll-boostrap 并尝试推送到我的 anthonybrown.github.com 并收到以下消息：
t67:anthonybrown.github.com anthonybrown$ git remote add origin
git@github.com:anthonybrown/anthonybrown.github.com.git fatal: remote origin already exists.
t67:anthonybrown.github.com anthonybrown$ git push origin master
To git@github.com:anthonybrown/anthonybrown.github.com.git
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git@github.com:anthonybrown/anthonybrown.github.com.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again. See the
'Note about fast-forwards' section of 'git push --help' for details.
t67:anthonybrown.github.com anthonybrown$ git push --help
我究竟做错了什么 ？？？
