git main branch 提交远程仓库失败

通常在用git clone了remote端（服务器）的git仓库后，再进行了自己一系列修改后，会将自己测试后稳定的状态push到remote端，以更新源仓库，使 其他人在pull的时候得到自己的修改。但是在git push的时候会经常出现如下的错误提示。

remote: error: refusing to update checked out branch: refs/heads/master

remote: error: By default,
updating the current branch in a non-bare repository

remote: error: is denied, because it will make the index and work tree inconsistent

remote: error: with what you pushed, and will require ‘git reset –hard’ to match

remote: error: the work tree to HEAD.

remote: error: You can set ‘receive.denyCurrentBranch’ configuration variable to

remote: error: ‘ignore’ or ‘warn’ in the remote repository to allow pushing into

remote: error: its current branch; however, this is not recommended unless you

remote: error: arranged to update its work tree to match what you pushed in some

remote: error: other way.

remote: error: To squelch this message and still keep the default behaviour, set

remote: error: ‘receive.denyCurrentBranch’ configuration variable to ‘refuse’.

根据上面所报的信息，它的意思就是默认情况下，git不允许用push操作更新non-bare的仓库，因为这样的操作会导致remote仓库的索引 （index）和工作树（work tree）与你push的不一致，此时需要通过‘git reset –hard’操作来使得工作树与HEAD索引相匹配。 可以通过在remote端，设置git的配置文件（.git/config），在其中添加如下内容：

[receive]

denyCurrentBranch = false

这样就可以通过git push提交自己的稳定更新，要想在push后在remote端看到更新的效果，执行git reset --hard即可。
