这和看起来一样简单。

cd /d c:\
git clone C:\folder1 folder2

从git克隆的文档:

对于本地存储库，git也支持本地存储库，可以使用以下语法: / / repo.git / /路径 file:///path/to/repo.git/ 这两种语法基本上是等价的，除了前者暗示了—本地选项。

使用git克隆c:/folder1 c:/folder2

git clone [--template=<template_directory>] [-l] [-s] [--no-hardlinks]
[-q] [-n] [--bare] [--mirror] [-o <name>] [-b <name>] [-u <upload-pack>]
[--reference <repository>] [--separate-git-dir <git dir>] [--depth <depth>]
[--[no-]single-branch] [--recursive|--recurse-submodules] [--]<repository>
[<directory>]


<repository>

    The (possibly remote) repository to clone from.
    See the URLS section below for more information on specifying repositories.
<directory>

    The name of a new directory to clone into.
    The "humanish" part of the source repository is used if no directory 
    is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
    Cloning into an existing directory is only allowed if the directory is empty.

走这条路对我来说没用。

以下是我在MacOS上最终发挥作用的方法:

cd ~/projects
git clone file:///Users/me/projects/myawesomerepo myawesomerepocopy

这也奏效了:

git clone file://localhost/Users/me/projects/myawesomerepo myawesomerepocopy

如果我这样做，路径本身是有效的:

git clone --local myawesomerepo myawesomerepocopy

值得一提的是，该命令在Linux上的工作原理类似:

git clone path/to/source/folder path/to/destination/folder
