Ruby Question

Rails could not find a temporary directory (ArgumentError)

I'm uploading my Rails proyect to a Ubuntu Server running 12.04LTS and I can't seem to fix this issue! Whether I do a bundle install or try to use the whenever gem I get that error! I've read a lot but still I'm unable to fix it

/lib/ruby/2.0.0/tmpdir.rb:34:in `tmpdir': could not find a temporary directory (ArgumentError)

And my ls -la of the / folder

Any ideas?
P.s I tried chmod -R 777 on /tmp with no luck


Your Ubuntu installation probably doesn't have TMPDIR set. You should set that variable in your startup.
