# Ruby apps
# Lazy-loading rbenv
Since v3.1.44 it is possible to initialize rbenv helper code on first-run thus improving shell load times. Set
~/.bashrc. A first-time invocation of
rbenv will initialize rbenv code, shimming the path as needed.
# Selecting Ruby versions
It is strongly recommended to select a Ruby version other than system default.
Example: to change Ruby versions
rbenv install 2.4.3 rbenv local 2.4.3 # Set 2.4.3 as the default system interpreter rbenv global 2.4.3
