Bundler dying even though HOME variable is set - amazon-web-services

Question

My issue is very similar to that described in issue deploying rails 5 application to AWS using Elastic Beanstalk due to rb-readline
However, setting HOME and/or HOMEPATH via the AWS console has not helped. I get the same error, every time. Here is the relevant logfile:

When I log on to the EC2 instance, I can verify that $HOME is set as expected, but I still get the above result. I hypothesize that maybe the problem I'm having is that the app is started in some chrooted configuration and the directories I'm choosing don't exist? Or maybe I need to use "path syntax" with ":" characters?
But trial-and-error is going to take a long, long time here, I'm redownloading via dashboard with every try. So if someone has something more definitive, I'd really appreciate it.

Answer 1

Well, I have solved this. I eliminated the rbreadline gem from my build. This was causing the problem. I had to solve another problem to do this, first I looked at rails console doesn't load due to libreadline
However the solution given,
ln -s /usr/local/opt/readline/lib/libreadline.dylib \
/usr/local/opt/readline/lib/libreadline.6.dylib
did not work. What worked for me was
ln -s /usr/local/opt/readline/lib/libreadline.dylib \
/usr/local/opt/readline/lib/libreadline.6.2.dylib
