# {username}:~/environment $ rvm version
rvm 1.29.8 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]
# {username}:~/environment $ rvm seppuku
Are you SURE you wish for rvm to implode?
This will recursively remove /home/ec2-user/.rvm and other rvm traces?
(anything other than 'yes' will cancel) > yes
Removing rvm-shipped binaries (rvm-prompt, rvm, rvm-sudo rvm-shell and rvm-auto-ruby)
Removing rvm wrappers in /home/ec2-user/.rvm/bin
Hai! Removing /home/ec2-user/.rvm
/home/ec2-user/.rvm has been removed.

Note you may need to manually remove /etc/rvmrc and ~/.rvmrc if they exist still.
Please check all .bashrc .bash_profile .profile and .zshrc for RVM source lines and delete or comment out if this was a Per-User installation.
Also make sure to remove `rvm` group if this was a system installation.
Finally it might help to relogin / restart if you want to have fresh environment (like for installing RVM again).

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.

For more info see:
https://github.com/svenfuchs/i18n/releases/tag/v1.1.0

Post-install message from by_star:
Upgrading ByStar
----------------

* Chronic gem (used for time string parsing) has been removed as a hard dependency for ByStar,
however it is still supported. If you would like to use Chronic with ByStar, please explicitly
include `gem chronic` into your Gemfile.
Post-install message from rails_best_practices:
********************************************************************************

  rails_best_practices is a code metric tool to check the quality of rails codes.

  I highly recommend you browse the Rails Best Practices website first.

Railsアプリのconfig.i18n.fallbacks = trueを確認し,
I18n (>= 1.1.0) と Rails (< 5.2.2.2) を使用している場合は
'config.i18n.fallbacks = [I18n.default_locale]'とする。
そうでない場合、フォールバックはI18n 1.1.xでアプリ内で壊れるらしい
