Yesterday I upgrade macOS Sierra, When I brew upgade,appeared error:

     Warning: You are using OS X 10.12.
     We do not provide support for this pre-release version.
     You may encounter build failures or other breakages.
     Please create pull-requests instead of filing issues.

I search long time for solve for this problem ,

eg:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

or:

 sudo chown $(whoami):admin /usr/local && sudo chown -R $(whoami):admin /usr/local

And then reboot OS,there are still this problem.

/usr/local exists already, it can be writed.

So,I don't use brew upgrade, please help,I have a long time can't use it.

This worked for me :

sudo xcode-select -r
Edit and set the date of your Mac as October 1st, 2019
sudo xcodebuild -runFirstLaunch
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
brew upgrade

Install Homebrew. The missing package manager for macOS. This solved mine.

Steps:

1.Open Terminal.

2.Paste the line below.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

3.Hit return (It will do all of the processes by its own. I Hope this may help you).

You just have to upgrade to Homebrew 1.0.0 (1.1.0 or 1.2.0). Go to brew.sh and follow the instructions.

After trying everything else, the following code block finally did it for me ...

 cd "$(brew --repo)" && git fetch && git reset --hard origin/master && brew update

This code came from the brew README https://github.com/Homebrew/brew/#update-bug.
After running it, this is what I got ...

  ==> Migrating HOMEBREW_REPOSITORY (please wait)...
  Error: /usr/local/Homebrew already exists.
  Please remove it manually or uninstall and reinstall Homebrew into a new
  location as the migration cannot be done automatically.

I ignored the final error message, and went on with ...

  MacDePadre:local arick$ brew upgrade

I had a bunch of libraries that needed to be updated, so it took a long time, but this seemed to fix the problem.

I have same problem. This works for me:

Go to your terminal, type those command, change whoami to your username.

sudo chown -R $(whoami) /usr/local
xcode-select --install

You will give write permission to /usr/local and also you will download and install Command Line Developer Tools from Apple, it may take like 1~2 mins.

Try to run upgrade in case of you are seeing such error:Homebrew: Error: update-report should not be called directly

brew upgrade

Now do the update. 

brew update

In the end you will see:

Homebrew no longer needs to have ownership of /usr/local. If you wish
you can return /usr/local to its default ownership with:   sudo chown
root:wheel /usr/local

just do it:

sudo chown root:wheel /usr/local
