# Installation
|
||
|
||
Instructions for a supported install of Homebrew are on the [homepage](https://brew.sh).
|
||
|
||
This script installs Homebrew to its preferred prefix (`/usr/local`
|
||
for macOS Intel, `/opt/homebrew` for Apple Silicon and `/home/linuxbrew/.linuxbrew` for Linux) so that
|
||
[you don’t need sudo](FAQ.md#why-does-homebrew-say-sudo-is-bad) when you
|
||
`brew install`. It is a careful script; it can be run even if you have stuff
|
||
installed in the preferred prefix already. It tells you exactly what it will do before
|
||
it does it too. You have to confirm everything it will do before it starts.
|
||
|
||
## macOS Requirements
|
||
|
||
* A 64-bit Intel CPU or Apple Silicon CPU <sup>[1](#1)</sup>
|
||
* macOS Catalina (10.15) (or higher) <sup>[2](#2)</sup>
|
||
* Command Line Tools (CLT) for Xcode: `xcode-select --install`,
|
||
[developer.apple.com/downloads](https://developer.apple.com/downloads) or
|
||
[Xcode](https://itunes.apple.com/us/app/xcode/id497799835) <sup>[3](#3)</sup>
|
||
* The Bourne-again shell for installation (i.e. `bash`) <sup>[4](#4)</sup>
|
||
|
||
## Git Remote Mirroring
|
||
|
||
You can set `HOMEBREW_BREW_GIT_REMOTE` and/or `HOMEBREW_CORE_GIT_REMOTE` in your shell environment to use geolocalized Git mirrors to speed up Homebrew's installation with this script and, after installation, `brew update`.
|
||
|
||
```bash
|
||
export HOMEBREW_BREW_GIT_REMOTE="..." # put your Git mirror of Homebrew/brew here
|
||
export HOMEBREW_CORE_GIT_REMOTE="..." # put your Git mirror of Homebrew/homebrew-core here
|
||
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
|
||
```
|
||
|
||
The default Git remote will be used if the corresponding environment variable is unset.
|
||
|
||
## Alternative Installs
|
||
|
||
### Linux or Windows 10 Subsystem for Linux
|
||
|
||
Check out [the Homebrew on Linux installation documentation](Homebrew-on-Linux.md).
|
||
|
||
### Untar anywhere
|
||
|
||
Just extract (or `git clone`) Homebrew wherever you want. Just avoid:
|
||
|
||
* Directories with names that contain spaces. Homebrew itself can handle spaces, but many build scripts cannot.
|
||
* `/tmp` subdirectories because Homebrew gets upset.
|
||
* `/sw` and `/opt/local` because build scripts get confused when Homebrew is there instead of Fink or MacPorts, respectively.
|
||
|
||
However do yourself a favour and use the installer to install to the default prefix. Some things may
|
||
not build when installed elsewhere. One of the reasons Homebrew just
|
||
works relative to the competition is **because** we recommend installing
|
||
here. *Pick another prefix at your peril!*
|
||
|
||
```sh
|
||
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
|
||
```
|
||
|
||
or
|
||
|
||
```sh
|
||
git clone https://github.com/Homebrew/brew homebrew
|
||
```
|
||
|
||
then
|
||
|
||
```sh
|
||
eval "$(homebrew/bin/brew shellenv)"
|
||
brew update --force --quiet
|
||
chmod -R go-w "$(brew --prefix)/share/zsh"
|
||
```
|
||
|
||
### Multiple installations
|
||
|
||
Create a Homebrew installation wherever you extract the tarball. Whichever `brew` command is called is where the packages will be installed. You can use this as you see fit, e.g. a system set of libs in the default prefix and tweaked formulae for development in `~/homebrew`.

|
||
## Uninstallation
|
||
|
||
Uninstallation is documented in the [FAQ](FAQ.md).
|
||
|
||
<a name="1"><sup>1</sup></a> For 32-bit or PPC support see
|
||
[Tigerbrew](https://github.com/mistydemeo/tigerbrew).
|
||
|
||
<a name="2"><sup>2</sup></a> 10.15 or higher is recommended. 10.10–10.14 are
|
||
supported on a best-effort basis. For 10.4-10.6 see
|
||
[Tigerbrew](https://github.com/mistydemeo/tigerbrew).
|
||
|
||
<a name="3"><sup>3</sup></a> Most formulae require a compiler. A handful
|
||
require a full Xcode installation. You can install Xcode, the CLT, or both;
|
||
Homebrew supports all three configurations. Downloading Xcode may require an
|
||
Apple Developer account on older versions of Mac OS X. Sign up for free
|
||
[here](https://developer.apple.com/register/index.action).
|
||
|
||
<a name="4"><sup>4</sup></a> The one-liner installation method found on
|
||
[brew.sh](https://brew.sh) requires the Bourne-again shell, i.e. bash.
|
||
Notably, zsh, fish, tcsh and csh will not work.
