git-svn not a git command?

While attempting to get an old svn dump of a project under git control, I ran into an interesting problem. Whenever I run git svn, I get an error saying it isn't a git command, yet there is documentation for it that I can pull up using git help. Is there something wrong with my install, or am I just missing something here?

Edit: I should probably also mention that I am running msysGit version 1.6.1.9.g97c34 under Windows XP, and the error I get is:

$ git svn
git: 'svn' is not a
git-command. See 'git --help'.

Did you mean one of these?
fsck
show

I just check on my newly installed ubuntu box and it wasn't installed even with git-core installed. A simple:

sudo apt-get install git-svn

or your distro equivalent should fix it.

On Ubuntu:

sudo add-apt-repository ppa:git-core/ppa
apt-get update
sudo apt-get install git-svn

I am not sure that git svn has ever worked with recent Git Windows distribution (post 1.5.6).

Many problems have been reported before, so git svn may very much be not included in current msysGit releases.

Another current active "Git on Windows" development mingw.git does state in its README that svn does not work.

This thread of Msysgit does suggest that git svn may be reintegrated at some points, but progress are still slow.

Update: from MSysGit1.6.2 (early March 2009), git-svn works again. See this SO question.

---

Update: with a modern (2017) Git for Windows 2.x, git svn is already included.
No need for sudo apt-get install git-svn, which would only be possible in a WSL (Windows Subsystem for Linux) shell session anyway.

Under my system I've had this trouble:

$ git svn
Can't locate SVN/Core.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.10.0
/usr/lib/perl5/5.10.0/i486-linux-thread-multi

/usr/lib/perl5/vendor_perl .) at
/usr/libexec/git-core/git-svn line 29.

because I don't have Subversion Perl bindings installed. Try installing them and running the command again.

For posterity: On CentOS 7, just run sudo yum install git-svn.

It wasn't installed on my fresh install of Ubuntu on WSL -

sudo apt install git-svn

sorted it:

❯ git svn
git-svn - bidirectional operations between a single Subversion tree and git
...

I had the same error under Cygwin 1.7. It was solved by installing the git-svn package with Cygwin setup.

On Gentoo , you should build git with USE="subversion"

MacPorts version:

port install git +svn

(Note: you likely need to port deactivate git first)

On CentOS I used

sudo yum install git-svn

Had a similar problem on RHEL6, i.e., > Can't locate Git/SVN.pm in @INC (@INC contains: /usr/local/share/perl5 /usr/local/lib64/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/libexec/git-core/git-svn line 25.

My solution:

sudo yum install subversion-perl
chmod 755  /usr/local/share/perl5/ (and sub dirs, as they were only readable by root)

If git-svn is not part of mSysGit, I recommend using a small UNIX server to host your gateway repository that clones your svn repository, and then clone that repository onto your Windows machine. This is the approach I am using for interacting with CVS from git.

On Fedora I had to install it with

sudo dnf install -y git-svn
