昨天,我发布了一个关于如何从我的一台机器克隆Git存储库到另一台机器的问题,我如何从另一台机器“克隆Git”?
现在我可以成功地将Git存储库从源存储库(192.168.1.2)克隆到目标存储库(192.168.1.1)。
但是当我对文件进行编辑,git commit -a -m "test"和git push时,我在目的地(192.168.1.1)上得到了这个错误:
git push
hap@192.168.1.2's password:

我正在使用两个不同版本的Git(远程上的1.7版本和本地机器上的1.5版本)。这是一个可能的原因吗?
旧版本的Git允许推入当前签出的非裸库分支。
事实证明,这是一件非常令人困惑的事情。所以他们添加了你看到的警告信息,这也是非常令人困惑的。
如果第一个存储库只是充当服务器,那么按照其他答案的建议将其转换为裸存储库,然后就可以完成了。
然而,如果你需要在两个都在使用的回购之间有一个共享分支,你可以通过下面的设置来实现
Repo1 -将充当服务器,也用于开发
Repo2—仅用于开发
按如下方式安装Repo1
创建一个分支来共享工作。
git branch shared_branch
为了安全起见,您还应该创建一个$(REPO)。Git /hooks/update拒绝对shared_branch以外的任何内容的任何更改,因为你不想让别人乱动你的私有分支。
repo1/.git/hooks (GIT_DIR!)$ cat update
#!/bin/sh
refname="$1"
oldrev="$2"
newrev="$3"
if [ "${refname}" != "refs/heads/shared_branch" ]
then
echo "You can only push changes to shared_branch, you cannot push to ${refname}"
exit 1
fi
现在在repo1中创建一个本地分支,您将在其中执行实际工作。
git checkout -b my_work --track shared_branch
Branch my_work set up to track local branch shared_branch.
Switched to a new branch 'my_work'
(可能需要git配置——global push.default upstream,以便git push工作)
现在您可以使用
git clone path/to/repo1 repo2
git checkout shared_branch
此时,您已经设置了repo1和repo2,以便在本地分支上工作,从repo1中的shared_branch中进行推和拉操作,而无需担心错误消息或repo1中的工作目录不同步。您使用的任何正常工作流都应该工作。
使用Git,两个常规(非裸)存储库不能直接来回推/拉文件。必须有一个中间裸存储库。显然,这有点像一对已婚夫妇有了一个孩子,但这对夫妇要离婚了。父母之间不会相互交谈,但他们会通过孩子进行交流。
因此,您有一个存储库,您将这个存储库克隆到一个裸存储库,然后将其克隆到第三个。第一个和第三个可以通过第二个存储库(裸存储库)交换信息。我想这是有道理的,因为你不希望别人在未经你同意的情况下将东西签入你的存储库,因为这可能会导致合并冲突等。
这里有一个例子:
在PC上,在~/workspace
git init
echo "line 1" > afile.txt
git add .
git commit -m ‘initial import’
git clone --bare . ../remote-repository.git
git remote add origin ../remote-repository.git
git push --set-upstream origin master
在笔记本电脑上,在~/workspace中(不要init git等)
git clone //LJZ-DELLPC/remote-repository.git/ .
//然后进行各种提交,并推送它们:
echo "line 2" > afile.txt
git add afile.txt
git commit -m 'added line 2'
git push
然后回到PC,在~/workspace中
git pull
//然后进行各种提交,并推送它们:
git push
在笔记本电脑
git拉
等等。
下面是一台机器上的一个绝对具体的例子,直接从命令窗口复制,这样我们就知道没有遗漏任何步骤,它确实可以工作,等等:
