zest.releaser with plone.releaser breaks when not in a buildout.coredev environment

[thet]

I have installed zest.releaser, plone.releaser and zest.releaser.towncrier in a central python virtualenv, which is available to my whole system.

When releasing a package which is not in Plone's buildout.coredev, zest.releaser gives me just before the end of the release process this error - note - up to uploading to pypi everything works fine:

Upload to pypi.quaive.net (Y/n)? n
Upload to quaivepypi.syslab.com (Y/n)? n
Ok to update coredev versions.cfg/checkouts.cfg? (Y/n)? n

Maybe zest.releaser / plone.releaser should be more forgiving in a non-Plone coredev environment.

That would be something to fix in plone.releaser. Please open an issue in https://github.com/plone/plone.releaser/issues

BTW, I would not install plone.releaser anywhere else than in buildout.coredev.

that probably fixes the issue. thanks!
