chef-solo error Errno::ENOENT: No such file or directory - solo.rb

Question

I'm trying to install nginx via the opscode cookbook on Ubuntu 12.04 server. I know it depends on ohai so I have that cookbook downloaded as well. When I run

$ sudo chef-solo -c solo.rb

i get an error saying

FATAL: Errno::ENOENT: No such file or directory - solo.rb

Not sure how solo.rb is missing when it's in my current directory.

$ ls
cache  cookbooks  node.json  node.json~  solo.rb  solo.rb~

Here is the output from debug

$ sudo chef-solo -l debug -c solo.rb

Answer 1

This is due to the way chef works. It changes directory to / to avoid any kind of permissions issues, but this means plugins that need access to command line arguments won't know how to get to your relative paths any more.

There is a bug filed with the chef code to address the issue.

For now, using full paths for your chef-solo arguments fixes the problems. E.g.

$ chef-solo -c /full/path/to/solo.rb -j /full/path/to/node.json -l debug

Or as someone else pointed out, removing the /etc/chef/ohai_plugins/README file will also "fix" the problem. Although not in a real way, since all that is doing is triggering a modification time update on the ohai_plugins folder, triggering chef to reload everything. That functionality is not guaranteed and may break before the aforementioned bug is fixed.
