I upgraded from Mohave to Big Sur and found that homebrew is not working any more. I installed the command line tools using the command
xcode-select --install After I run brew list, I get the following error
~ brew list Traceback (most recent call last): 11: from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in `<main>' 10: from /usr/local/Homebrew/Library/Homebrew/brew.rb:23:in `require_relative' 9: from /usr/local/Homebrew/Library/Homebrew/global.rb:37:in `<top (required)>' 8: from /usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby/2.6.3/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 7: from /usr/local/Homebrew/Library/Homebrew/vendor/portable-ruby/2.6.3/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 6: from /usr/local/Homebrew/Library/Homebrew/os.rb:3:in `<top (required)>' 5: from /usr/local/Homebrew/Library/Homebrew/os.rb:21:in `<module:OS>' 4: from /usr/local/Homebrew/Library/Homebrew/os/mac.rb:58:in `prerelease?' 3: from /usr/local/Homebrew/Library/Homebrew/os/mac.rb:24:in `version' 2: from /usr/local/Homebrew/Library/Homebrew/os/mac.rb:24:in `new' 1: from /usr/local/Homebrew/Library/Homebrew/os/mac/version.rb:26:in `initialize' /usr/local/Homebrew/Library/Homebrew/version.rb:368:in `initialize': Version value must be a string; got a NilClass () (TypeError) I tried by deleting the folder /Library/Developer/CommandLineTools and installing the Command Line Tools for Xcode 12.3 beta but still I am getting the same error. Is there any way to make brew work?

brew/Library/Homebrew/cmd/update-reset.sh this will destroy all your uncommitted or committed changes. # speedup when using Git repeatedly and prevent errors if the shim changes mid-update.
Now brew should work just fine under macOS Big Sur! [email protected]: Permission denied (publickey). fatal: Could not read from remote repository.
If your Mac uses the Apple Silicon (M1 Chip), you will have a problem with the installation till the date of publication of this article. You can read in this another article how to solve the issue of Homebrew that doesn't run on the M1 chip.
but running this on Big Sur, with the latest version of Xcode (12.2) installed via the App Store will throw this error: Your CLT does not support macOS 11.0 Log into Apple’s Developer Site and download the beta of Xcode, version 12.3 as of this writing.
5 If you run brew upgradestill meet the error, maybe you should run brew updatefirst. My experience is: 1. brew update 2. brew doctor 3. brew upgrade Share Improve this answer Follow answered Nov 16 '20 at 6:06 TerryTerry 5111 bronze badge 1 1 Warning: You are using macOS 11.0.
You should update brew;
brew update-reset I had the same problem. Try upgrading brew - this solved it for me.
