Fix error: rails console No such file to load -- irb/encoding_aliases.rb (LoadError)

I got this error after upgrading Ruby from 2.4.5 to 2.6.4 when I opened the Rails console - rails server still worked.

Running via Spring preloader in process 14679
Loading development environment (Rails 5.2.2.1)
Traceback (most recent call last):

The solution is to upgrade the gem binding_of_caller Show archive.org snapshot to version 0.8.0.

Found that solution here Show archive.org snapshot .
