You don’t have write permissions for the /Library/Ruby/Gems/2.6.0 directory.

It is recommended to install a separate Ruby instance, beside the one that is delivered and mainly used by macOS to prevent unexpected side effects.

To do so, follow the listed instructions.

1. Install Homebrew.
2. Install rbenv (a version manager for Ruby).
3. Make sure you updated your .zshrc or .bash_profile content according to the rbenv init description.
   • You may need to add export PATH=”$HOME/.rbenv/bin:$PATH” to the start of your .zshrc or .bash_profile as well.
4. Install a stable or required Ruby version.
5. Run `rbenv global 2.7.0`
6. Run `rbenv rehash`
7. Now you should be able to install new Gems.
