git svn - Unrecognized URL scheme error

Question

I'm getting the following error on attempt to clone svn rep with git svn:

eugene$ git svn clone https://my.site/svn/ here
Initialized empty Git repository in /Users/eugene/Documents/workspace/test/here/.git/
Bad URL passed to RA layer: Unrecognized URL scheme for 'https://my.site/svn' at /usr/local/git/lib/perl5/site_perl/Git/SVN.pm line 148.

svn checkout https://my.site/svn/ works just fine.

I've re-run

cpan SVN::Core

and install finished fine, but still getting the error.

Solution 1

Apparently you have two different versions of Subversion binaries and one of those versions does not support http(s):// protocol.

If you run svn --version the output should include something like this:

* ra_neon : Module for accessing a repository via WebDAV protocol using Neon.
  - handles 'http' scheme
  - handles 'https' scheme

or

* ra_serf : Module for accessing a repository via WebDAV protocol using serf.
  - handles 'http' scheme
  - handles 'https' scheme

The problem is that git-svn does not use the same binaries. Instead it uses another version of SVN that compiled with no support for http(s):// protocol. There may be different reasons for that:

1. If svn --version -q prints 1.7.x, most probably your Git installation is too old to use this version of SVN. So, you might want to upgrade it as latest versions of git-svn support SVN 1.7.

2. If your default SVN installation has no Perl binding installed, SVN::Core uses the binaries with no http(s) support as a fallback. So, you might want to enable Perl bindings for SVN.

3. Finally, due to some misconfiguration of Perl modules, PATH/LD_LIBRARY_PATH or PERL5LIB (or whatever git-svn uses to find the libraries — I'm no expert here), git-svn just uses invalid binaries.

The particular steps on fixing the issue depend on how you manage the packages, e.g. with Homebrew that'd look like this:

$ brew remove svn
$ brew install --with-perl svn

or

$ brew remove git
$ brew install git

Or with MacPorts something like this:

$ port install subversion-perlbindings

or

$ port upgrade git-core +svn

After that try to specify a proper library path. E.g. if which svn prints /usr/local/bin/svn, try to use /usr/local/lib as a library path for Perl modules.

Hope that helps.

Can you do: git svn --version

See this question: How to upgrade the SVN version used by git-svn

UPDATE

Please note that this answer was in response to the posters original version of the question where the issue may have been related to using an older version of svn in git-svn. The poster has since upgraded git, determined that it wasn't the cause, and adjusted the question to reflect that.

bash-3.2$ git svn --version git-svn version 1.7.7.5 (Apple Git-26) (svn 1.6.17)

Is it old? Can it be a problem?

I wouldn't have thought so, but you could try installing git 1.8 as that now supports svn 1.7. That might fix your issue.

Your issue looks similar to this? git.661346.n2.nabble.com/…

Possibly related: If you are using homebrew for OS X then make sure you install package svn, not subversion.

great, the git svn --version output is "git-svn version 2.10.1 (svn 1.8.11)", so I reinstall git solved my problem via brew reinstall git, now the output of "git version" print git-svn version 2.17.0 (svn 1.7.20)
