在使用git commit时遇到错误：Your branch is up-to-date with 'origin/master'，根本原因是没有建立分支或者没有指定分支的问题。可使用以下方法解决。
新建一个分支
$ git branch busbranch
切换分支
$ git checkout busbranch
重新提交你的改动提交到新分支上
$ git add .
$ git commit -m "my test commit"
合并到主仓库中
$ git checkout master
$ git merge busbranch
最后可以push到服务器
$ git push -u origin master
所有的命令整理如下：
eddy@test-ppc MINGW64 /e/gitee/monsys (master)
$ git commit -m "my test commit"
On branch master
Your branch is up-to-date with 'origin/master'.
Changes not staged for commit:
