Fixes mismatch between expected gem version and installed gem version.
As of now installed version of gem in prod is
3.0.3
, when we expectit to be 2.6.10.
In Dockerfile in we were copying
/usr/local/bin/gem
, which is justa loader and doesn't decide rubygems version.
Copying
/usr/local/lib/ruby/2.6.0/rubygem
from builder would most likelywork but this seems unconventional and doesn't really save as much build time.
