How to Fix the "Your CLT does not support macOS 11" error in macOS
I recently got this error while using Homebrew to install a package on macOS, in my case rbenv:
➜ brew install rbenv
...
Error: Your CLT does not support macOS 11.
It is either outdated or was modified.
Please update your CLT or delete it if no updates are available.
Update them from Software Update in System Preferences or run:
softwareupdate --all --install --force
If that doesn't show you an update run:
sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
Alternatively, manually download them from:
~https://developer.apple.com/download/more/~.
Error: An exception occurred within a child process:
SystemExit: exitWeird!
Running softwareupdate --all --install --force as suggested in the message didn’t help, so I ran sudo rm -rf /Library/Developer/ and then sudo xcode-select --install:
That’s it.
After doing this, brew install rbenv worked fine.
