Got this after upgrading to v1.11.0

Hi after upgrading to new version, my AWS no longer can find the .irbrc file.

I think this is likely related to #817, which surfaces errors that were previously swallowed.
Can you help me debug the problem with these steps:

1. Add something like puts "root irbrc is loaded" to /root/.irbrc
2. Switch back to an IRB version that previously worked (e.g. v1.10.0)
3. Start IRB and see if that message is printed

And based on the result, we'll learn what's the root problem:

• If the message is not printed, it means that /root/irbrc was never loaded successfully, even though it exists. I think it may be caused by permission issues.
• If the message is printed, it means #817 changed the loading behaviour unexpectedly.

I think IRB was not loading /root/.irbrc in previous version too. irb-1.11.0 is just fixed to show the error which was hidden before.

I think you have ENV['IRBRC'] specified. According to the log, rvm is adding it, and the specified irbrc file has a bug in line 9.
I think the content of irbrc is same or similar to this one.
https://github.com/rvm/rvm/blob/84ab322b44d88540c24d5e102a4dae0bbe17ce7e/scripts/irbrc

if ENV["rvm_path"].nil?
  # Should check file existence before require, or rescue from LoadError
  # It does not load `/root/.irbrc` but loads `/root/irbrc`. This is not IRB way.
  require File.join(ENV["HOME"], "irbrc")
else
  require File.join(ENV["rvm_path"], "scripts", "irbrc")
end

Workaround for the error message in rvm's irbrc way is to rename /root/.irbrc to /root/irbrc.

I will do the test, but I am curious why is it /root/irbrc and not /root/.irbrc with a "dot" there.

I'm closing because it's a problem of rvm.
