Since none of the commands of programs installed using brew did not work (e.g. although mysql and mongodb are both installed, commands like mongod or mysql on terminal prompted a command not found error), I was trying many solutions to solve the issue. In the meanwhile, I just found out that the /usr/local/bin folder is broken on my computer; if anyone got a solution, please let me know and thank you very much for your time!
P/S: My computer specs are: 16" Macbook Pro 2021 M1 Max
Screenshot
For M1 Macs, brew's bin folder is located at /opt/homebrew/bin.
which brew would display the full path for binary, and brew --prefix would show you the prefix path (it would work for both arm and x86 OS).
$ which brew
/opt/homebrew/bin/brew
$ brew --prefix
/opt/homebrew

Context:
I have a macbook air M1
Example: I have homebrew installed and when I type
which brew
I get
/opt/homebrew/bin/brew
But when I check my path variables, this folder isn't there.
How is my shell still able to locate the brew binary?
EDIT: to clarify, I mean how am I still able to do something like
brew --help
If the brew binary is not in my path
I'm on the M1 MacBook.
This is the error when I try to install Homebrew:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Homebrew is not (yet) supported on ARM processors!
Rerun the Homebrew installer under Rosetta 2.
If you really know what you are doing and are prepared for a very broken experience you can use another installation option for installing on ARM:
https://docs.brew.sh/Installation
So how do I "Rerun the Homebrew installer under Rosetta 2."?
Got an answer from a developer in the Homebrew github https://github.com/Homebrew/brew/issues/9173
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Use this to install packages:
arch -x86_64 brew install <package>
If you have not yet installed Rosetta 2 to emulate Intel CPUs on ARM Macs, you will get the error arch: posix_spawnp: /bin/bash: Bad CPU type in executable. Prompt a Rosetta 2 installation with:
softwareupdate --install-rosetta
I have two instances of brew installed, the Intel version that runs using Rosetta2 and which installs to /usr/local/bin and the Arm version that runs natively and installs to /opt/homebrew/bin. Now it is all working, I do not have to start iTerm using Rosetta.
I have these aliases to reach the two versions.
ibrew='arch -x86_64 /usr/local/bin/brew'
mbrew='arch -arm64e /opt/homebrew/bin/brew'
I have the native version in my path first:
path=( /opt/homebrew/bin /opt/homebrew/opt /usr/local/bin /usr/bin /bin /usr/sbin /sbin /Library/Apple/usr/bin )
Now I can try mbrew search and mbrew install. If they work, I am good to go with a native program. For example:
mbrew install ag
If brew fails I try building from source, with verbose output, e.g.
mbrew install -sv rust
Be warned, this takes a while and may still fail.
If it still fails, (and mbrew install -sv go results in a segmentation fault for me) I have two choices. Use ibrew search and ibrew install to get the Intel build instead, or examine the verbose output and look for problem dependencies. In some cases an install -s on the dependencies is enough to get the native brew to work.
I must stress that native brew always prints this warning
Warning: You are running macOS on a arm64 CPU architecture.
We do not provide support for this (yet).
Reinstall Homebrew under Rosetta 2 until we support it.
So proceed at your own discretion.
For completeness, and assuming you have iTerm2, Rosetta2 and the Xcode command line tools installed, I did this to install brew under Rosetta (with credit to all those who have posted on this page before me):
Copy the installed iTerm2.app application to iRosetta2.app
Press command+I to Get Info for iRosetta.app, click Open Using Rosetta2
Run iRosetta2 and use this command from https://brew.sh
Like so
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)
alias ibrew='arch -x86_64 /usr/local/bin/brew' # put this in ~/.zshrc
And I did this to install native brew, taken from other contributors to Stack Overflow and the Homebrew alternative installation site, using iTerm2 without Open Using Rosetta2
mkdir ~/homebrew
curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
sudo mv ~/sudo mv homebrew /opt
mbrew='arch -arm64e /opt/homebrew/bin/brew' # for .zshrc
export PATH="/opt/homebrew/bin:/opt/homebrew/opt:$PATH" # also for .zshrc
Edit
Time has passed and I have changed the architecture to arm64e following Fernando García Redondo observation. Now the warning about Arm architecture not supported has gone and Rust and Go install without problems and without compiling from source. I assume the good people at Homebrew have been working hard over Christmas. Thanks!
Edit Feb 21
The Homebrew team have announced that they support Apple silicon. So I wondered if I could delete my aliases and just use brew to install for Apple silicon. The short answer is no! if you run brew from /usr/local without the arch -x86_64, it complains that /usr/local is reserved as the Intel default prefix and using /opt/homebrew is required. So I will retain my two aliases and try mbrew first and only use ibrew if the native brew fails.
Another option is by going into your applications in Finder, select Terminal and press ⌘+I and check the "Open using Rosetta" option.
Sorry if the formatting is off, first time posting a solution.
The easiest way to run Homebrew is with Rosetta 2.
1. Duplicate Your Favourite Terminal for Rosetta
Find your favourite terminal, right-click to duplicate it, and rename it for easier identification. In this example, I'm using the default Terminal app on Big Sur 11.2.1.
Right-click the Terminal Rosetta and go to Get Info to check the Open using Rosetta option.
2. Install Homebrew
Open the rosetta terminal and run the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Running this command will ask you for the password, and then it will provide you with the information of what all it will install and which new directories it will create.
3. Using Homebrew
Once HomeBrew is installed, you can start using it to install your required packages into the M1 Mac.
Run the following command to get brew help:
brew help
To install a package, you can run the following command:
brew install packagename
That’s all about installing and getting started with Homebrew on Apple M1 Macs.
EDIT: Thanks all! Upvote to help other devs! Homebrew 3.0.0 now officially supports Apple Silicon (https://brew.sh/2021/02/05/homebrew-3.0.0/)
After I installed Rosetta, I added an alias so I can use brew install <package> as I would normally.
alias brew='arch -x86_64 brew'
I agree with everyone else in that you need to add the arch -x86_64 in front of the original command so thought to include that alias to help anyone finding this thread in the future
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" worked on my new M1 Mac
Do below
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
alias brew='arch -x86_64 brew'
brew install azure-cli
now try az login. you are good to go
You can change the setting of Terminal to launch it using Rosetta.
Go to your Application/Utilities folder, right click on the Terminal App and check the tick box 'Open using Rosetta'
But to be honest, I have Homebrew installed without Rosetta. Just removed the x86 version yesterday and installed a fresh version without Rosetta.
I'm trying to remove duplicate opencv versions on my mac. It seems that I have installed using both homebrew and mac port, so I decided to uninstall mac port completely, following this guide
But when I uninstalled mac-port and softwares installed with port, I couldn't use softwares installed by brew anymore
$ brew install pkg-config
$ pkg-config
-bash: /opt/local/bin/pkg-config: No such file or directory
I guess it's because the system still believes that pkg-config is in mac-port location. But how to fix it? I haven't find solutions with google.
Thanks in advance!
problem solved by editing PATH setting in ~/.bash_profile (or bashrc).
I'm trying to setup an SSHFS share from my local machine to a remote machine, but it is not working. I'm getting the error OSXFUSE file system is not available (see below). How to fix this??
FYI, my local machine is a MacBook Pro laptop running OSX 10.9.3. The remote machine is actually a VirtualBox on the same hardware running CentOS.
% brew install sshfs # <---- SSHFS is installed
Warning: sshfs-2.5.0 already installed

the OSXFUSE file system is not available (1)
I tried solution described here. But it didn't work for me:
% sudo kextunload -b com.github.osxfuse.filesystems.osxfusefs
(kernel) Kext com.github.osxfuse.filesystems.osxfusefs not found for unload request.
Failed to unload com.github.osxfuse.filesystems.osxfusefs - (libkern/kext) not found.
If you run brew info osxfuse and follow the instructions to the letter, I believe it would work.
From what You described, you just tried unloading the (possible) previous kernel extension, but did not complete the last important step to actually install the new extension.
This is what brew info osxfuse tells me:
If upgrading from a previous version of osxfuse, the previous kernel extension
will need to be unloaded before installing the new version. First, check that
no FUSE-based file systems are running:
mount -t osxfusefs
Unmount all FUSE file systems and then unload the kernel extension:
sudo kextunload -b com.github.osxfuse.filesystems.osxfusefs
The new osxfuse file system bundle needs to be installed by the root user:
sudo /bin/cp -RfX /usr/local/opt/osxfuse/Library/Filesystems/osxfusefs.fs /Library/Filesystems
sudo chmod +s /Library/Filesystems/osxfusefs.fs/Support/load_osxfusefs
There appears to be a problem loading the KEXT installed by the regular osxfuse Homebrew package. You can use brew cask to install the official FUSE for OS X build from their own DMG:
brew rm osxfuse
brew install caskroom/cask/brew-cask
brew cask install osxfuse
SSHFS itself is also available as a Cask package, though on my system mixing osxfuse from Cask with plain sshfs binary bottle works just fine.
The downside to this approach is that brew upgrade or brew outdated will no longer be able to update FUSE for OS X as brew cask is not version-aware for now.
I have observed that OSXFUSE is a bit tricky, though I don't know exactly why, and brew tries to avoid changing the system, so using it to manage kernel extensions is not a good idea. I suggest using the packaged installers for OSXFUSE and SSHFS from http://osxfuse.github.io/ instead of using brew.
Open System Preferences, choose FUSE, then update to the latest version. Thats what worked for me.
The problem when installing SSHFS with brew is that osxfusefs is not signed: the Console outputs com.apple.kextd: ERROR: invalid signature for com.github.osxfuse.filesystems.osxfusefs, will not load. See also https://github.com/osxfuse/osxfuse/issues/122.
The binary for OSXFUSE from http://osxfuse.github.io/ (as suggested by the answer of Old Pro) does not have this problem, and therefore installing this one instead resolved it for me.
I installed MongoDB via Homebrew (following http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/) but it's not working.
Typing mongod at shell prompt gives me:
-bash: mongod: command not found
Not sure if I need to add something for Homebrew to my PATH env var?
I can see Mongo is installed under /usr/local/Cellar/mongodb – but am assuming I don't need to add everything I install via homebrew to the path? Also, assuming I can run mongod from any directory or am I actually meant to be in install directory?
When I run brew doctor I get:
Warning: You have unlinked kegs in your Cellar
Followed by a list of 3 items which includes MongoDB – but I'm not sure how I'm meant to link them?
Works perfectly
brew update
brew tap mongodb/brew
brew install mongodb-community#4.2
For latest version, check https://docs.mongodb.com/manual/release-notes/
You're getting this error because your 'brew' install failed to create the correct symlinks in /usr/local/bin. As a result, the shell can't find the mongo executables in your $PATH. You can fix this using the following steps:
Check the permissions on /usr/local/bin and make sure that you own that directory and have write permissions on it
$ ls -ld /usr/local/bin
Once you've fixed that, run 'brew link' to fix the symlinks
$ brew link mongodb
If you are on mongodb-community#4.0. You can try to reinstall with brew reinstall mongodb-community#4.0.
Then I get the following hint:
==> Caveats
mongodb-community#4.0 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have mongodb-community#4.0 first in your PATH run:
echo 'export PATH="/usr/local/opt/mongodb-community#4.0/bin:$PATH"' >> ~/.bash_profile
So you can just copy the echo command and restart your shell!
Copied from a different channel running these commands in the terminal updated the installation/configuration issues as described in OP
brew tap mongodb/brew
brew install mongodb-community
brew services start mongodb-community
I faced the same problem and this solution seemed to work for me. I had previously uninstalled mongodb and reinstalled it through homebrew which gave me a bunch of problems. This solution seemed to work just fine.
brew uninstall --force mongodb
brew cleanup -s mongodb
brew cleanup --prune-prefix
brew install mongodb
It works from the directory since the sh searches the ENV path and then the cwd for a program named mongod. I have been looking around a little and it seems that the default install of MongoDB (I am not a Mac user) does not install a rc or init script for which sh to understand it's running behaviour as stated here:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/#using-mongodb-from-homebrew-and-macports
The packages installed with Homebrew and MacPorts contain no control
scripts or interaction with the system’s process manager.
If you have configured Homebrew and MacPorts correctly, including
setting your PATH, the MongoDB applications and utilities will be
accessible from the system shell. Start the mongod process in a
terminal (for testing or development) or using a process management
tool.
So you must actually define (as you said) MongoDBs path, here is an example: https://snipt.net/sido/installing-mongodb-on-os-x/
Edit: the example is not mine. I just stole it from it's user: https://snipt.net/sido/
