pip freeze | could not find svn URL in dependency_links

  • 772

I get this error when I run pip freeze:

Warning: cannot find svn location for apsw==3.7.17-r1
...
## FIXME: could not find svn URL in dependency_links for this package:
apsw==3.7.17-r1

What does this mean? And how can I fix it?

    This is a two-part problem.

    Firstly the error is a known bug in pip. It seems to mean that one of the packages (apsw here) was installed directly from a subversion repository but that the reference to it (so that it can be recreated) wasn't stored properly so it can't be referenced properly in a freeze-list.

    To half-explain and half-compound that issue apsw isn't available in the shops on pypi. Its modern documentation says as much:

    APSW is not available at the Python Package Index (pypi) and hence cannot be installed using easy_install, pip or similar tools.

    I'm personally not sure if I agree with that. Pip has been able to do checkout-based installations for a while. Here's a real example one I have:

    pip install -e git+https://github.com/danirus/django-pagedown.git@b67da0a5c68c8f1d75922afe7f5dc8eac3172a0b#egg=django_pagedown-dev

    You might be able to bend that format to your will with something like this:

    pip install -e git+https://github.com/rogerbinns/apsw.git@8e09f8aec2b759cf7de3532490505f71c60c74da#egg=apsw

    Who knows. Play around. Oh and you might need to remove it manually first.
