Ruby, Software | Ruby: rbenv global not changing the ruby version

When you plan to run multiple versions of ruby, rbenv comes in handy.

Some of the commands that comes in handy when you work with rbenv are listed below

# To install rbenv (mac)
$ brew install rbenv

# To list all available ruby versions
$ rbenv install -l

# To install a specific ruby version
$ rbenv install 2.6.8

# To set the ruby version globally in the system
$ rbenv global 2.6.8

# Check what version is showing up
$ ruby -v

Sometimes, the changes may not have been added in the user shell settings. Edit ~/.bash_profile or ~/.zprofile or ~/.zshrc depending on your default shell and add in the below lines to the end of the file

# Include rbenv in ZSH shell
export PATH=”$HOME/.rbenv/bin:$PATH”
eval “$(rbenv init -)”

Save the file and open up a new terminal.

Now repeat the rbenv steps to setup the desired version and finally check the ruby version installed.
