I'm trying to install MongoDB server on macOS Big Sur using brew, I'm following the documentation on the official mongo website.
I run the following command:

brew tap mongodb/brew

after that, I run:

brew install mongodb-community@4.4

but I got the following error:

Error: No similarly named formulae found.
Error: No available formula with the name "mongosh" (dependency of mongodb/brew/mongodb-community).
It was migrated from mongodb/brew to homebrew/core.

For me homebrew-core was not tapped properly.

 brew doctor


Warning: Homebrew/homebrew-core was not tapped properly! Run:
  rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-core"
  brew tap homebrew/core

Warning: Some taps are not on the default git origin branch and may not receive
updates. If this is a surprise to you, check out the default branch with:
  git -C $(brew --repo homebrew/core) checkout master

We need to remove and tap homebrew/core again.

rm -rf "/opt/homebrew/Library/Taps/homebrew/homebrew-core"
brew tap homebrew/core

After this we need to tap mongodb/brew

brew tap mongodb/brew

And then install mongodb-community

brew install mongodb-community

It worked for me.

You need to remove tap by running brew untap mongodb/brew.

Then you can run brew install mongodb-community@4.4 and it will install from the core homebrew tap, where the package now lives.

For me, this was linked to the homebrew core being missing as per https://github.com/Homebrew/discussions/discussions/1512

steps: run the command

brew config

if you get Core tap HEAD: (none) in the body, then likely you had the same issue as me. Run the command

brew tap homebrew/core

You can then go back to the installation steps


brew tap mongodb/brew

brew install mongodb-community@6.0

And everything should install correctly (it did for me anyway).

Run this command in terminal:

rm -fr $(brew --repo homebrew/core)

Then try:

 brew install mongosh

It work perfectly
