I am trying to install brew on my co-worker's macOS. I have brew on my computer.
Not sure why we are having problems to install it on his computer. I am following this turial.
When I run:
% brew doctor
zsh: command not found: brew
It says brew was not installed.
I already edited his path at .zshrc. However, I did not put the comment suggested on the tutorial. Not sure if it makes any difference:
#Michaels-MacBook-Air ~ % cat .zshrc
export PATH=/usr/local/bin:$PATH
This is on:
#Michaels-MacBook-Air ~ % pwd
/Users/michaels
In addition, I already executed:
/bin/bash install.sh
Which return the following warning:
Warning: /opt/homebrew/bin is not in your PATH.
Instructions on how to configure your shell for Homebrew
can be found in the 'Next steps' section below.
And I checked xcode-select is installed:
#Michaels-MacBook-Air ~ % xcode-select --version
xcode-select version 2396.
I am suspicious his PATH might be wrong:
#Michaels-MacBook-Air ~ % echo $PATH
/usr/local/bin:/usr/local/bin:/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/Keybase.app/Contents/SharedSupport/bin
Is this problematic?
If no, what else could be causing a problem?
From the Homebrew documentation:
This script installs Homebrew to its default, supported, best prefix (/usr/local for macOS Intel, /opt/homebrew for Apple Silicon and /home/linuxbrew/.linuxbrew for Linux)
If your coworker has an M1 or M2 mac, you'll need to add /opt/homebrew/bin to PATH.
To install brew, just run the following script:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Homebrew Official Documentation:
https://brew.sh/
I use the latest Apple M1 chip processor. And I keep getting errors while application installation.
say.,
brew install openjdk#11
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
Please create a new installation in /opt/homebrew using one of the
"Alternative Installs" from:
https://docs.brew.sh/Installation
You can migrate your previously installed formula list with:
brew bundle dump
Need help with exact steps to follow.
For what it's worth, before installing Homebrew you will need to install Rosetta2 emulator for the new ARM silicon (M1 chip). I just installed Rosetta2 via terminal using:
/usr/sbin/softwareupdate --install-rosetta --agree-to-license
This will install rosetta2 with no extra button clicks.
After installing Rosetta2 above you can then use the Homebrew cmd and install Homebrew for ARM M1 chip: arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Once Homebrew for M1 ARM is installed use this Homebrew command to install packages: arch -x86_64 brew install <package>
Homebrew needs to be installed in two places on Apple silicon: in /usr/local for rosetta-emulated (Intel) code, and /opt/homebrew for ARM64. These are somewhat hard-coded and the /opt/homebrew one MUST be used for ARM code, as it stands today, and is non-negotiable. However, it's easy enough to install and you can follow the general instructions on the official docs. You open a Rosetta shell first.
% arch -x86_64 zsh
% cd /usr/local && mkdir homebrew
% curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
Later, to install tools under intel you can use the arch command per-command or open a zsh terminal as above.
arch -x86_64 /usr/local/homebrew/bin/brew install sometool
For the ARM architecture, you don't need to use arch but you do need to use the full path of the homebrew command.
/opt/homebrew/bin/brew install sometool
You could rename the brew commands to something like brew86 and brewARM to help keep them separate.
Run this in the terminal it fixes the issue
eval "$(/opt/homebrew/bin/brew shellenv)"
Just use:
arch -arm64 brew install package-name
replace 'package-name' with the package you want to install.
Did a temporary fix by enabling Open using Rosetta option in the terminal app from Utilities folder.
However, it would be great to know the actual solution for this question to use the native way.
There is a lot of helpful info in the replies here, but there doesn't seem to be a direct answer to the original request, "Need help with exact steps to follow."
In case it may help people facing this issue in the future, I'll share the exact steps that I followed to resolve the issue.
The following CLI commands are intended to be run on an Apple silicon-equipped Mac in the built-in Terminal application running the macOS-default shell, Zsh:
Run a Homebrew command to confirm that an error like the following appears:
$ brew install <formula>
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
Please create a new installation in /opt/homebrew using one of the
"Alternative Installs" from:
https://docs.brew.sh/Installation
Or:
$ brew doctor
Warning: Your Homebrew's prefix is not /opt/homebrew.
Some of Homebrew's bottles (binary packages) can only be used with the default
prefix (/opt/homebrew).
You will encounter build failures with some formulae.
If either of these errors appears, it is likely that the steps below are applicable to your case.
Navigate to the /opt folder:
$ cd /opt
Create a folder named homebrew. By default superuser privileges are required to write inside of the /opt folder, which means that it is necessary to use sudo:
$ sudo mkdir homebrew
Grant write access to the homebrew folder so that your user can perform the Homebrew installation:
$ sudo chmod go+w homebrew
Perform the four steps listed on the "Alternative Installs" page (the page mentioned in the first error message in step 1):
Install Homebrew:
$ curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
Set Homebrew's prefix in your current Terminal session:
$ eval "$(homebrew/bin/brew shellenv)"
Update Homebrew:
$ brew update --force --quiet
Revoke write access to specific folders and files:
$ chmod -R go-w "$(brew --prefix)/share/zsh"
Set Homebrew's prefix in future Terminal sessions by adding the necessary command to one of Zsh's startup files. As far as I can tell, .zshrc is the preferred startup file for this type of command:
$ echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zshrc
Note that if there are any other existing Terminal sessions on your machine that have been open since before running the above command, the correct Homebrew prefix will still be unset in those sessions.
Confirm that Homebrew's prefix is now properly set:
$ type -a brew
brew is /opt/homebrew/bin/brew
brew is /usr/local/bin/brew
Or:
$ brew doctor
Your system is ready to brew.
It should now be possible to continue using Homebrew normally.
This issue with new macbook pro M1 chip
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
For Resolve follow below steps
Step1
$ brew bundle dump
Step2
$ /bin/bash -c "$(curl -fsSL
https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Step3
Edit file below
$ vi ~/.bashrc or vi ~/.zshrc
Edit below line in above file
export PATH=/opt/homebrew/bin:$PATH
Homebrew is now available for the new apple M1 chip at https://docs.brew.sh/Installation. The script installs in a new location, ‘/opt/homebrew’ instead of ‘/usr/local’ which requires that you implement a couple lines of script after the install, substituting your username. You can copy/paste from the comments in your install. Just don’t skip these steps.
==> Next steps:
- Add Homebrew to your PATH in /Users/[username]/.zprofile:
echo 'eval "$(/opt/homebrew/bin/brew [username])"' >> /Users/[username]/.zprofile
eval "$(/opt/homebrew/bin/brew [username])"
Note: This works for a clean install of Homebrew on a new machine. If you have already installed an old version of Homebrew and got it working, I believe you need to uninstall that first -or- you may find this a quicker work-around http://blog.wafrat.com/homebrew-on-mac-with-m1/. Not tested.
See: https://docs.brew.sh/Installation
1. Clone homebrew
$ cd /opt
$ sudo git clone https://github.com/Homebrew/brew homebrew
2. Chown dir
$ sudo chown -R $(whoami):staff /opt/homebrew
3. Update new brew shellenv temporarily, more shellenv meaning see man brew
$ eval "$(homebrew/bin/brew shellenv)"
4. New brew update
$ brew update --force --quiet

eval "$(/opt/homebrew/bin/brew shellenv)"
This also may occur if you are trying to run your command in IntelliJ Terminal. Just try to run in (Regular) Terminal.
First run this command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
then it will ask you a question, hit return, then wait for the installation to be completed. After than run this command:
brew bundle dump
Go over to https://brew.sh and use the command. It will download and install brew again correctly.
Run this command as this will resolve the issue
arch -arm64 brew install kotlin
I had installed Homebrew using iTerm enabled for the Apple ARM chip (M1), but when using a different terminal program that was Intel-based (and thus opening in Rosetta) I got this error. The latter app is seen as Intel, and thus wants to use the older Homebrew path.
Probably this error is related running brew on M1/M2 Mac instead instead of Intel based Mac, atleast that was in my case. I had previously restored a Time Machine backup from Intel to M2.
According to the Homebrew documentation, the default installation script installs Homebrew to its preferred /usr/localfor macOS Intel and /opt/homebrew for Apple Silicon.
You can well use this, as it worked well for me-
re-install brew by running this in your terminal /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
run brew bundle dump
You should be good on using brew
So I bought a new M1 and migrated to it. I took it back and migrated back. I was receiving this error. Found that I needed to run sudo rm -Rf /opt/homebrew after re-installing brew to get things flowing again. 16G Ram on the M1 didn't replace my workflow with Intel using 64G.
I removed ALL content from /usr/local/bin folder (including 'brew'). Homebrew isn't working anymore and I seem to be stuck in a limbo. When I try to install it says:
It appears Homebrew is already installed. If your intent is to
reinstall you should do the following before running this installer
again:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
When I run the given uninstall command it says:
Failed to locate Homebrew!
Background
The problem arose when I attempted to remove node.js by following this guide:
https://stackoverflow.com/a/11178106/1736012
To completely uninstall node + npm is to do the following:
go to /usr/local/lib and delete any node and node_modules
go to /usr/local/include and delete any node and node_modules directory
if you installed with brew install node, then run brew uninstall node in your terminal
check your Home directory for any local or lib or
include folders, and delete any node or node_modules from there
go to /usr/local/bin and delete any node executable
Especially 5 was bad! That's what led me to remove everything under /usr/local/bin. So brew doctor won't work (brew isn't recognized anymore). Brew worked fine before this.
What I tried
This does not work either as brew is missing:
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )"
I tried various scripts like this one for example: https://apple.stackexchange.com/a/85481. And this: https://gist.github.com/SteveBenner/11254428. None of them is working (both assumes that brew command is there)...
What can I do to re install Homebrew so that it works as before??
This should bring back a working brew command:
cd /usr/local/Homebrew
git init
git remote add origin https://github.com/Homebrew/homebrew
git pull origin master
Next I would check the output of brew doctor and see if there are major problems. There is an official uninstalling guide on homebrew's github wiki in case you want to completely uninstall.
Try to move or remove the Homebrew file in the user/local file and then try the regular link from the homebrew homepage to install the brew!
By the way, I did not try moving but I am pretty sure it should work.
Note: While the operation you might have to use the sudo
I faced the same issue, the following link really worked for me

Installing Homebrew on macOS
(24 answers)
Closed 2 years ago.
I've spent the bulk of my Friday trying to get the latest version of Ruby installed on my new MacBook Air (w/ Mountain Lion installed).
I have all the latest versions of XCode and command line tools. But I can't seem to get Homebrew to work! Here's a screenshot of where I keep getting stuck (I'm a new user, so can't embed this image).
As you can see I used the following to instal Homebrew:
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go/install)"
While there was a "warning" it seemed as though the installation worked:
Warning: /usr/local/bin is not in your PATH.
==> Installation successful!
Despite that, when I try to run "brew doctor" I received the following:
-bash: brew: command not found
Again, I'm trying to install homebrew, so i can instal the latest version of ruby -- I'm looking to learn to code in ruby, but kind of screwed if I can even get a development environment running! :)
The warning is telling you what is wrong. The problem is that brew is kept in /usr/local/bin
So, you can try /usr/local/bin/brew doctor
To fix it permanently alter your bash profile (.bashrc or .profile in your home directory) and add the following line:
export PATH=/usr/local/bin:$PATH
On Apple silicone it's
export PATH=/opt/homebrew/bin/:$PATH
Check XCode is installed or not.
gcc --version
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew doctor
brew update
http://techsharehub.blogspot.com/2013/08/brew-command-not-found.html "click here for exact instruction updates"
nano ~/.profile
add these lines:
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
save the file:
Ctrl + X then Y then Enter
then render the changes:
source ~/.profile
This was just happening to me, but none of the suggestions above worked. I changed directories ("cd ~/tmp") and suddenly the command
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
worked for me. Prior to changing directories I had been in a directory that is a Git repository. Perhaps that was interfering with the ruby and Git commands in the Brew install script.
You can run in terminal
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/linuxbrew/go/install)"
then install https://github.com/robbyrussell/oh-my-zsh.
When those complate run i.e pico editor pico .zshrc and past those lines:
export PATH="$HOME/.linuxbrew/bin:$PATH"
export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH"
export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH"
remember use brew doctor :)
try this
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/linuxbrew/go/install)"
You can use this:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
to install homebrew.
I seem to have dug myself into a corner.
I was halfway through installing Homebrew the first time and it got stuck. After ~15 minutes of waiting I quit terminal. My original input was what's from the homebrew homepage.
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
I reopened terminal and tried to re-install and got -
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
So, as suggested, I ran
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
and got
-bash: brew: command not found
I tried to run the uninstall script from the Homebrew FAQ and that didn't seem to help either. Anything else I can try? How would I manually uninstall?
So what happens now if you run ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)" again?
After you killed terminal did you ps auxw | grep -E 'ruby|curl' and kill those?
Are you using /usr/local for anything else? If not, you can rm -rf /usr/local and run the install command again.
I'm not a pro at terminal but I found a line in my .gitconfig that prevented me from running the install:
[push]
default = simple
After commenting that line out of my .gitconfig the install ran beautifully.
If you run rm -rf /usr/local you might get permission denied or risk deleting files of other installed programs. Deleting only /usr/local/Homebrew/ folder worked for me
