python - How can I avoid tox reinstalling dependencies and deleting my break point? -


i'm using tox v2.7 , need set pdb break point in dependency library of library i'm testing/debugging. can't stop tox reinstalling library , therefore wiping out change made including break point.

i find flag, i'm not using it:

 -r, --recreate        force recreation of virtual environments

how can tell tox install dependency packages if don't exist @ all?

the tox.ini in question: https://github.com/belugame/django-auth-ldap/blob/master/tox.ini
