#2 Py 2.7 virtualenv - AttributeError: 'module' object has no attribute 'comments'

[Anthon van der Neut]

I tested yaml.cmd running in a cleanly created virtualenv and got an immediate crash when trying to read a directory with YAML files.

I had installed default via pip. Normally I would expect this to run and to output a YAML file combining the contents of the YAML files in the directory.

Can you try to do this in a new virtualenv with version 0.2.4. You should also use

yaml from-dirs yamlstuff/*.yaml

Please close if 0.2.4 fixes your problem

This now works right but it seems to me that I can't close the issue since I accidentally created it when logged out.

Thanks very much for the response though.
