Hi, Thank you for this.

Quick question, How do you unset the global version to previous?

[ponessa]

Thanks!

Good day, I am new to M1. Upon running rbenv init I get env: bash: No such file or directory. I am sure that rbenv was installed as running install command again will throw

Warning: rbenv 1.2.0 is already installed and up-to-date.
To reinstall 1.2.0, run:
  brew reinstall rbenv

I believe in the newest macOS, zsh has replaced bash as default shell.

I have added this line eval "$(rbenv init - zsh)" into my ~/.zshrc.

Maybe that's something you can try as well.

isn't changing the global version of ruby may ruin the os itself?

MacOS 12.4. At the build stage of Ruby 3.0.3 and 3.2.1, there is a build error in openSSL. ruby-build: using gmp from homebrew,

Skip the Ruby install. Do the install of Cocoapods through Brew.

Thanks for this, this is super useful!

[ucals]

This was useful, but it didn't work. After rbenv global, I had to run rbenv rehash to force the system to recognize the new ruby as the default.

[sd4483]

If anyone is not able to set the latest installed ruby version as default even after running rbenv global ..., run rbenv rehash after running rbenv global ...

Thanks to @ucals for pointing this out!!

[varmiguemunoz]

Hey guysss, It doesn't work. The default ruby version is still there, even after run rbenv rehash command line. Anyone can help me? My macbook is a Macbook Air M1, arm64.
