Chef never successfully completed! Any errors should be visible in the
output above. Please fix your recipes so that they properly complete.

The VM is up, just something wrong with chef configuration, probably due to the update of other softwares. Please advice, thanks!

I just went through this too. Bear in mind that I don't know the first thing about 'chef' ...

The problem is that the 'python' chef plugin is deprecated and no longer supported. Other projects have the same issue that were resolved using poise-python

If someone knows what substitutions need to be made to change the 'python' to 'poise-python', that would be the solution. I just don't know anything about 'chef'.

If your VM is up and running, this solution appears to work : https://github.com/ptwobrussell/Mining-the-Social-Web-2nd-Edition/issues/319
