psych.rb:297:in `initialize': no implicit conversion from nil to integer (TypeError)

I see this currently with visage-app on Ubntu server 12.10.

psych (1.3.4)
bundler (1.2.2)

After trudging through these I have an empy yaml file that visage is trying to open:

-rw-r--r-- 1 root root 0 Nov 29 21:28 /var/lib/gems/1.9.1/gems/visage-app-2.1.0/lib/visage-app/config/profiles.yaml

Even when removing this file visage still fails to start until I copy the default profile.yaml over to the one that's empty:

cp /var/lib/gems/1.9.1/gems/visage-app-2.1.0/features/support/config/default/profiles.yaml /var/lib/gems/1.9.1/gems/visage-app-2.1.0/lib/visage-app/config/profiles.yaml

I had posted this over on the Bundler thread too. It seems like the consensus is psych doesn't handle empty files very well?

[lureze]

same here (except on debian wheezy)
thanks for the workaround, eegilbert

[swasher]

same on ubuntu 12.10
thanks eegilbert, it's work

[adamclerk]

Works for me too

On debian wheezy the paths are different. The following worked for me:

cp /usr/lib/ruby/gems/1.9.1/gems/visage-app-2.1.0/features/support/config/default/profiles.yaml /usr/lib/ruby/gems/1.9.1/gems/visage-app-2.1.0/lib/visage-app/config/profiles.yaml

UPDATE: on another system, also running debian wheezy, however with the ruby1.9.3 package installed instead of the ruby1.9.1 package, the above paths didn't work. The updated paths that did work are:

cp /var/lib/gems/1.9.1/gems/visage-app-2.1.0/features/support/config/default/profiles.yaml /var/lib/gems/1.9.1/gems/visage-app-2.1.0/lib/visage-app/config/profiles.yaml
