I tried
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
But I got errors
It appears Homebrew is already installed. If your intent is to reinstall you should do the following before running this installer again:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
The current contents of /usr/local are bin Cellar CONTRIBUTING.md etc Frameworks heroku Homebrew include lib n opt README README.md sbin share SUPPORTERS.md var .gitignore
So I tried
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Failed to locate Homebrew!
So I tried
rm -rf /usr/bin/.git and chown username /usr/local
But still the same.
How can I fix this issue. I need to have a fresh start.
My final purpose is to update current ruby2.0 to 2.2
Consider reading the Homebrew FAQ.
Scroll down the 4th FAQ listing enumerating :
How do I uninstall Homebrew ?
Alternatively, try running this and then run the uninstall procedure as mentioned above -
cd /usr/local
git init
git remote add origin https://github.com/Homebrew/homebrew
git pull origin master

I am trying to install homebrew on macos m1 chip, with the one-line command but keep running into the following error. Could someone please help me to fix this? Thank you.

Removing the directory and trying to reinstall worked for me.
sudo rm -rf /opt/homebrew
Please run the following commands in your terminal:
rm -fr $(brew --repo homebrew/core) # because you can't `brew untap homebrew/core`

Had a similar issue on Mac, I uninstalled it first by typing the command below and I installed Xcode, it worked for me after running the install command again.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
I first installed it onto my Linux system using the command recommended on the homebrew install page:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
but it seem to take a long time, and "hung" showing the output:
Resolving deltas: 100% (793706/793706), done.
for quite a while. I was impatient and killed the process then, and tried the install again. That is when I got the error reported by the OP. The fix was to uninstall the partially installed homebrew, and install again:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
When I tried to install homebrew I got this error. It started simple but then I was perplexed.
cjbrigna$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

No problem, github was down for a little while. So I tried again later.
cjbrigna$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Which makes me think I have homebrew.
cjbrigna$ brew help
-sh: brew: command not found
Well clearly I didn't have homebrew.
cjbrigna$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Failed to locate Homebrew!
Well now I can't install or uninstall homebrew. This makes no sense. What did I do wrong? I appreciate any help.
You can finish the install process manually:
cd /usr/local
git fetch origin master:refs/remotes/origin/master -n --depth=1
git reset --hard origin/master
Then ensure /usr/local/bin is in your PATH. If it is you should then be able to run e.g. brew help to check that Homebrew is installed.
I tried to install Homebrew like this:
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)"
It didn’t install correctly so I closed Terminal and tried again. Now it displays me the following message:
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
I tried to do that but without success. The following message is displayed:
brew: command not found
So, the problem is that Homebrew is installed but actually it is not installed. Any suggestions how to solve this problem? Thank you!
This seems to have resolved the issue for me
rm -rf /usr/local/Cellar /usr/local/.git
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Afterward, I can now
brew doctor
You may also find the gist linked to at the following page of use:
https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/FAQ.md
The URL contained in the command you are using is not correct. Ruby will dump out lines of HTML and then fail. Use this command instead:
ruby -e "$(curl -fsSkL raw.github.com/Homebrew/homebrew/go/install)"
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
this is work for me!
This worked for me:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
I removed the folder /usr/local/.git and homebrew installed just fine afterwards.
What was the message given when it didn't install correctly the first time? Is the brew binary present in /usr/local/bin ? If so, you probably just need to add it to your path, see: Error Installing Homebrew - Brew Command Not Found
Attempting to resolve the same issue, I found out that I had mistyped while making changes to my PATH. I did not have /usr/local/bin. I would then recommend running
$ echo $PATH
in terminal to see if you have the correct directories.You can also run
$ vi ~/.bash_profile
to see it and make changes if neccessary
If you cannot install by using curl try to open the install script from your browser, save it in a file called i.e brew_install.rb somewhere on your disk and run the script locally
ruby brew_install.rb
This worked for me.
Follow these steps
1 ==> ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
2 ==> sudo rm -rf /usr/local/Homebrew/
sudo rm -rf /usr/bin/Homebrew/
3 ==> install brew
1 -- /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2 -- sudo chown -R $(whoami) /usr/local/var/homebrew
If get these error try below command
Error: Failed to link all completions, docs and manpages:
sudo chown -R $(whoami) /usr/local/*
then follow these commands
/usr/local/bin/brew update --force
This is the most recent one that works for me.
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
I found it here in case it is updated later. https://brew.sh/
I am getting issues with permissions in Homebrew: After I installed Node and tried to install npm using the curl command Homebrew tells you to use, it would fail due to EACCESS errors. I checked the node folder and the permissions were a) unowned by a user (I had to chown it) and b) Had no write permissions (I had to chmod 755 it).
I've fixed the issue with NPM, but I had to run its install script as sudo (which is bad!).
I assume I must have installed Homebrew as root or something similar. I am hoping that reinstallation will fix it, but I can't find a source on how to reinstall Homebrew.
When I rerun the installer in Terminal I get:
/usr/local/.git already exists!
Update 10/11/2020 to reflect the latest brew changes.
Brew already provide a command to uninstall itself (this will remove everything you installed with Homebrew):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
If you failed to run this command due to permission (like run as second user), run again with sudo
Then you can install again:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Process is to clean up and then reinstall with the following commands:
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )"
Notes:
Always check curl | bash (or ruby) commands before running them
http://brew.sh/ (for installation notes)
https://raw.githubusercontent.com/Homebrew/install/master/install (for clean up notes, see "Homebrew is already installed")
Try running the command
brew doctor
and let us know what sort of output you get
edit: And to answer the title question, this is from their FAQ :
Homebrew doesn’t write files outside its prefix. So generally you can
just rm -rf the folder you installed it in.
So following that up with a clean re-install (following their latest recommended steps) should be your best bet.
For Mac OS X Mojave and above
To Uninstall Homebrew, run following command:
sudo ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
To Install Homebrew, run following command:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
And if you run into Permission denied issue, try running this command followed by install command again:
sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*
The way to reinstall Homebrew is completely remove it and start over. The Homebrew FAQ has a link to a shell script to uninstall homebrew.
If the only thing you've installed in /usr/local is homebrew itself, you can just rm -rf /usr/local/* /usr/local/.git to clear it out. But /usr/local/ is the standard Unix directory for all extra binaries, not just Homebrew, so you may have other things installed there. In that case uninstall_homebrew.sh is a better bet. It is careful to only remove homebrew's files and leave the rest alone.
For me, I need to do the below steps to re-install the brew from scratch.
sudo rm -rf /usr/local/Cellar/
brew cleanup
sudo rm -rf $(brew --repo)
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
You can try this method for M1 macbook
After you
1.Uninstall brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
2.Install brew again
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
3.You brew install something in image I "brew install sonar-scanner"
then error log show same this
Error: No similarly named formulae found.
4.You should try follow run this.
rm -rf "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core"
5.When no.4 is done run this
brew tap homebrew/core
try brew install again.
For me, this one worked without the sudo access.
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

I have tried multiple times. Can anybody tell me exact detailed steps?
My mac os is 10.6.8.
It complains about some missing packages.
Use this to install on Mac OSX 10.6.8
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Open terminal (shortcut : Press cmd + space and enter terminal in spotlight search)
Enter command /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Now you’ll be asked to enter password (note : passwords are not visible)
If you get permission error as below
fatal: cannot copy '/Library/Developer/CommandLineTools/usr/share/git-core/templates/hooks/pre-receive.sample' to '/usr/local/Homebrew/.git/hooks/pre-receive.sample': Permission denied
Failed during: git init -q
Enter command sudo chown -R $(whoami) $(brew --prefix)/*
Now you’ll be asked to enter password
Again enter the same command written in step 2 (shortcut : simply press top arrow button)
Wait patiently for sometime. You’ll see installation successful after a while.
Thereafter if you need any help regarding brew then simply enter brew help command. Refer this link for additional details.
brew.sh (the official home page) always has the most up-to-date installation instructions.
I got it working now following command /usr/bin/ruby -e "$(curl -fsSL raw.github.com/gist/323731)".
I was running the mkdir homebrew && curl -L github.com/mxcl/homebrew/tarball/master | tar xz --strip 1 -C homebrew I have no idea what the two are doing though
