I am using rbenv-vars as I have done many times to make available RAILS_MASTER_KEY in the env vars.
I have added the line to .rbenv-vars in project folder
RAILS_MASTER_KEY=XXXXX
I check with command rbenv vars, and it shows in the shell it's been added correcty
#-> export RAILS_MASTER_KEY='XXXXX'
But then my application fails to initialize because it doesn't find RAILS_MASTER_KEY, and checking with printenv, it isn't loaded.
What's going on?
