git使用过程出现的错误

1.错误1

fatal: remote origin already exists.

解决方法:

$ git remote rm origin

2.错误2

error: failed to push some refs to 'https://gitee.com/dongshuogit/XiaoGongJu.git'

hint: Updates were rejected because the remote contains work that you do

hint: not have locally. This is usually caused by another repository pushing

hint: to the same ref. You may want to first integrate the remote changes

hint: (e.g., 'git pull ...') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

这是是因为readme.md 没有存在在本地git中

执行git pull --rebase origin master 

就好了 ,现在遇到就这么多问题 以后再继续积累
