need help with whenever gem

it used to work just fine until a few days ago. now i am getting:

/home/railsuser/.rvm/gems/ruby-head/gems/bundler-1.16.4/lib/bundler/spec_set.rb:91:in `block in materialize': Could not find rake-12.3.1 in any of the sources (Bundler::GemNotFound)

i have added now this to my schedule.rb file:

ENV.each { |k, v| env(k, v) }

but it only generates now cron jobs for each env variable.

running bundle install on the command line is working just fine - as the same user…

any ideas?


nevermind - i updated rvm to latest & latest ruby. all good now
