python - pip freeze > requirements.txt error -

i getting next error command:

$pip freeze > requirements.txt warning: cannot find svn location distribute==0.6.16dev-r0

this requirements.txt file beforehand:

django==1.3 django-registration==0.7

first, i'd note not error, rather warning (though serious one).

this appears open issue in pip, judging issue page on github repository. problem arises when pip installing development version held on repository not svn. 1 illustration issue page provides:

mkvirtualenv test --no-site-packages workon test pip install flask==dev pip freeze > requirements.txt

it print result standard error:

warning: cannot find svn location flask==0.9-devdev-20120114

but file still have:

## fixme: not find svn url in dependency_links package: flask==0.9-devdev-20120114 jinja2==2.6 werkzeug==0.8.2 wsgiref==0.1.2

however, won't able utilize file in future install flask. see here:

mkvirtualenv test2 --no-site-packages workon test2 pip install -r requirements.txt

will output error:

downloading/unpacking flask==0.9-devdev-20120114 (from -r requirements.txt (line 2)) not find version satisfies requirement flask==0.9-devdev-20120114 (from -r requirements.txt (line 2)) (from versions: ) no distributions matching version flask==0.9-devdev-20120114 (from -r requirements.txt (line 2)) storing finish log in /users/dgrtwo/.pip/pip.log
