MacOs Catalina 未安装最新的 2.7.2 Ruby 版本

Question

Could somebody tell me how to install the latest version of Ruby? I've done

brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.zshrc
source ~/.zshrc

# Install Ruby
rbenv install 2.7.2
rbenv global 2.7.2
ruby -v

Besides while I'm running ruby -v :

ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]

Instead of 2.7.2. What have I missed?

Thanks

Try which ruby and see what comes up. If it's the system ruby and not the rbenv one, you need to add this to your profile:

export PATH="$HOME/.rbenv/shims:$PATH"
