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.

这个答案是基于Mercurial的经验，而不是Git，但这个经验告诉我们，如果你在不同的时间从不同的机器(对我来说是Mac、Unix和Windows)更新相同的基于Dropbox的存储库，那么以这种方式使用Dropbox会导致存储库损坏。

I don't have a complete list of the things that can go wrong, but here's a specific example that bit me. Each machine has its own notion of line-ending characters and how upper/lower case characters are handled in file names. Dropbox and Git/Mercurial handle this slightly differently (I don't recall the exact differences). If Dropbox updates the repository behind Git/Mercurial's back, presto, broken repository. This happens immediately and invisibly, so you don't even know your repository is broken until you try to recover something from it.

在用这种方法解决了一次混乱之后，我一直在使用下面的食谱，而且非常成功，没有任何问题的迹象。只需将存储库移出Dropbox。其他事情都用Dropbox;文档，JAR文件，任何你喜欢的东西。并使用GitHub (Git)或Bitbucket (Mercurial)来管理存储库本身。这两种工具都是免费的，所以不会增加成本，而且现在每种工具都发挥了自己的优势。

在Dropbox上运行Git/Mercurial除了风险什么都不会增加。不要这样做。

我认为Dropbox上的Git很棒。我一直在用它。我有多台电脑(两台在家里，一台在公司)，我把Dropbox作为一个中央的存储库。因为我不想把它托管在公共服务上，而且我也没有可以通过SSH访问的服务器，Dropbox通过在后台同步来解决这个问题(非常快)。

设置是这样的:

~/project $ git init
~/project $ git add .
~/project $ git commit -m "first commit"
~/project $ cd ~/Dropbox/git

~/Dropbox/git $ git init --bare project.git
~/Dropbox/git $ cd ~/project

~/project $ git remote add origin ~/Dropbox/git/project.git
~/project $ git push -u origin master

从那里，你可以克隆~/Dropbox/git/项目。git目录(无论它是否属于你的Dropbox帐户或在多个帐户之间共享)并执行所有正常的git操作-它们将自动同步到你所有的其他机器。

我写了一篇博客文章“关于版本控制”，其中介绍了环境设置背后的原因。它基于我的Ruby on Rails开发经验，但实际上它可以应用于任何东西。

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.

我也遇到过类似的问题，并为此创建了一个小脚本。我们的想法是尽可能简单地使用Dropbox和Git。目前，我已经快速实现了Ruby代码，不久将添加更多代码。

该脚本可在https://github.com/nuttylabs/box-git上访问。

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。

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
