Xcode CommandLineTools installed but still getting the error: Xcode alone is not sufficient on Monterey

Question

I have MacOS Montery 12.3.1 and I have already installed Xcode and installed CommandLineTools long time ago. I have Xcode-select version:

xcode-select version 2395.

Now, while trying to install heroku cli I got the error:

Error: Xcode alone is not sufficient on Monterey. Install the Command Line Tools: xcode-select --install

But the command:

xcode-select --install

the installation now would last 89 hours and it tries to download 15GB which can't be right...

sudo xcode-select --switch /Applications/Xcode.app
sudo xcode-select --switch /Library/Developer/CommandLineTools

I tried this but the second command throws the error:

xcode-select: error: invalid developer directory '/Library/Developer/CommandLineTools'

the folder CommandLineTools is in that directory... I am clueless. Thank you for your help.

Answer 1

The solution that worked for me was to deinstall Xcode(and everything related) and Homebrew. After reinstalling Xcode the CommandLineTools got installed with Homebrew and are working fine again.
