I am trying run knife backup export on a chef 0.10.10 server, and I got the following errors, do you have any ideas?

knife backup export -D chef-backup/ -VV

FYI, the knife-backup version caused is 0.0.5, but it works with 0.0.3. should it be the latest chef version 10.xx.xx+ needs keys for nodes, cookbooks, etc?

Thanks,
Stephen

0.0.4 should work also probably. Can you pls. tell me what ruby version are you running?

[Tak Lon (Stephen) Wu]

the ruby version is 1.8.7. (they are kinda old)

[Marius Ducea]

Can you please try it out with 0.0.6 and let me know.

[Tak Lon (Stephen) Wu]

yup, it works perfectly fine with v0.0.6!
