Git 常见问题

错误：failed to push some refs to

在使用git 对源代码进行push到gitHub时可能会出错，如下

$ git push -u origin master
To github.com:oceandlnu/oceandlnu.github.io.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'git@github.com:oceandlnu/oceandlnu.github.io.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.

出现错误的主要原因是github中的README.md文件不在本地代码目录中

可以通过如下命令进行代码合并[注：pull=fetch+merge]

1	git pull --rebase origin master

执行上面代码后可以看到本地代码库中多了 README.md 文件

此时再执行语句 git push -u origin master 即可完成代码上传到 github

错误：Git Push Error: insufficient permission for adding an object to repository database

进入项目 根目录/.git/objects ，yourname 替换为你的用户名， yourgroup 替换为你的用户所属组

1 2	cd .git/objects sudo chown -R yourname:yourgroup *
