ruby errors when running Passenger 4.0.48 and Ruby 2.0

[Csongor Gyuricza]

Background: I'm setting up puppet 3 with passenger/apache. After running a puppet client against the master, I see the following errors in the apache logs:

Hi, I see a lot of ' through your stack trace, I'm not sure if
that's related. There's no references to any passenger code though, so
I think it's something with puppet, but the html encoding makes it
really hard to decipher.

Kind regards,
Tinco

I believe this is an error in the puppet client, not in passenger. The puppet authors might be able to help you further.

In case someone else has this in the future - for me this for was caused by trying to run as a new system user without a home directory.

path_support.rb was trying to find the ENV['GEM_HOME'] and failing.  If you sudo as the user you'll find you can't gem env for example.

On linux you can use mkhomedir_helper [user] to create a home directory for the particular user you are trying to run passenger with.
