git 提交代码remote: error:updating the current branch in a non-bare repository is denied

问题：

开发机提交代码到远程仓库时，出错如下错误：

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: the work tree to HEAD.
remote: error:
remote: error: You can set 'receive.denyCurrentBranch' configuration variable to

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

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

! [remote rejected] master -> master (branch is currently checked out)
error: failed to push some refs to 'git@192.168.12.70:/data/orange'

解决办法：

在服务器端仓库目录下

$ cd /data/orange
$ git config receive.denyCurrentBranch warn

更好的办法：

error信息中已经给出提示：

“By default, updating the current branch in a non-bare repository is denied,”

服务器上配置代码仓库时，将代码库初始化为裸仓库，即使用命令:

$ git init --bare

这样，其他机器提交代码就不会有问题。
