正确的方法是使用git-remote-dropbox: https://github.com/anishathalye/git-remote-dropbox

在Dropbox中创建自己的裸回购会导致很多问题。Anish(库的创造者)解释得很好:

The root cause of these problems is that the Dropbox desktop client is designed for syncing files, not Git repositories. Without special handling for Git repositories, it doesn’t maintain the same guarantees as Git. Operations on the remote repository are no longer atomic, and concurrent operations or unlucky timing with synchronization can result in a corrupted repository. Traditional Git remotes run code on the server side to make this work properly, but we can’t do that. Solution: It is possible to solve this properly. It is possible to use Git with Dropbox and have the same safety and consistency guarantees as a traditional Git remote, even when there are multiple users and concurrent operations! For a user, it’s as simple as using git-remote-dropbox, a Git remote helper that acts as a transparent bidirectional bridge between Git and Dropbox and maintains all the guarantees of a traditional Git remote. It’s even safe to use with shared folders, so it can be used for collaboration (yay unlimited private repos with unlimited collaborators!). With the remote helper, it’s possible to use Dropbox as a Git remote and continue using all the regular Git commands like git clone, git pull, and git push, and everything will just work as expected.

对于使用Dropbox的小型团队:

如果每个开发人员在Dropbox上都有自己的可写裸存储库，这只对其他开发人员开放，那么这就有利于代码共享而没有损坏的风险!

然后，如果你想要一个集中的“主线”，你可以让一个开发人员从自己的回购中管理所有推送。

我不想把我所有的项目都放在一个Git存储库下，也不想为每个项目运行这些代码，所以我编写了一个Bash脚本来自动化这个过程。你可以在一个或多个目录上使用它——所以它可以为你完成这篇文章中的代码，也可以一次在多个项目上完成。

projects_to_git.sh -- Takes a project folder and creates a Git repository for it on Dropbox

USAGE:
    ./projects_to_git.sh file1 file2 ..

EXAMPLES:
    ./projects_to_git.sh path/to/MyProjectDir
        Creates a git project called MyProjectDir on Dropbox

    ./projects_to_git.sh path/to/workspace/*
        Creates a git project on Dropbox for every folder contained within the workspace directory, where the project name matches the folder name

I've been using Mercurial in the recommended manner and urge that you be cautious, especially if any of the machines differ. The Dropbox fora are full of complaints of mysterious filename case problems turning up spontaneously. Hg (and I presume Git) won't notice or complain during routine checkins and you'll only hear about the corruption when it complains of a corrupt repo when you try to use it for real. Bad news. Wish I could be more specific about the problem and its workarounds; I'm still trying to dig out from this mess myself.

还有一个开源项目(一个跨平台[Linux, Mac, Win]脚本的集合)，它用少量(3-4)命令完成存储库管理的所有细节。

https://github.com/karalabe/gitbox/wiki

示例用法如下:

$ gitbox create myapp
Creating empty repository...
Initializing new repository...
Repository successfully created.

$ gitbox clone myapp
Cloning repository...
Repository successfully cloned.

之后正常的git使用:

$ echo “Some change” > somefile.txt
$ git add somefile.txt
$ git commit –m “Created some file”
$ git push

查看项目wiki和手册以获得完整的命令参考和教程。

我不认为使用Git和Dropbox是正确的选择……想想两者的特点:

Git:

允许您拥有一个中央存储库 允许您使用自己的更改拥有自己的存储库 允许您从中央存储库发送和接收更改 允许多人更改相同的文件，他们合并他们或要求你合并他们，如果它不能这样做 web和桌面客户端是否允许访问中央存储库

Dropbox:

将所有内容保存在中央存储库中 允许您在服务器中拥有自己的文件版本 强制您从中央存储库发送和接收更改 如果多人更改相同的文件，第一个提交的文件将被稍后提交的文件所取代，并且不会发生合并，这很麻烦(这肯定是它最大的缺点) 具有web和桌面客户端以允许访问中央存储库。

如果你担心泄露你的文件，为什么不加密呢?然后你就可以得到Dropbox to Git的最大优势，那就是拥有公共和私人文件……
