# Installation
|
||
The suggested and easiest way to install Homebrew is on the
|
||
[homepage](http://brew.sh).
|
||
|
||
The standard script installs Homebrew to `/usr/local` so that
|
||
[you don’t need sudo](FAQ.md#wiki-sudo) when you `brew install`. It is a
|
||
careful script, it can be run even if you have stuff installed to
|
||
`/usr/local` already. It tells you exactly what it will do before it
|
||
does it too. And you have to confirm everything it will do before it
|
||
starts.
|
||
|
||
There are other ways to install Homebrew which provide you with more
|
||
flexibility. They are listed below the requirements.
|
||
|
||
## Requirements
|
||
* An Intel CPU <sup>[1](#1)</sup>
|
||
* OS X 10.6 or higher <sup>[2](#2)</sup>
|
||
* Command Line Tools for Xcode: `xcode-select --install`,
|
||
https://developer.apple.com/downloads or
|
||
[Xcode](https://itunes.apple.com/us/app/xcode/id497799835) <sup>[3](#3)</sup>
|
||
* A Bourne-compatible shell for installation (e.g. bash or zsh) <sup>[4](#4)</sup>
|
||
|
||
If you want to build software that utilizes X11 components, you’ll need
|
||
to install [XQuartz](https://xquartz.macosforge.org). Apple provided a
|
||
distribution of XQuartz (“X11.app”) prior to OS X 10.8. This is
|
||
supported where possible, but many projects now require more up-to-date
|
||
libraries than those in the Apple distribution, so installing the
|
||
[latest version available for your
|
||
OS](https://xquartz.macosforge.org/trac/wiki/Releases) is recommended.
|
||
On 10.8 and newer, you should install the [most recent
|
||
version](https://xquartz.macosforge.org).
|
||
|
||
If you want to build Java bindings (in software such as Subversion,
|
||
Berkeley-DB, CMake, etc.) Apple’s “Java Developer Update” is required.
|
||
The latest versions are “Update 10” for 10.5 and “Update 9” for 10.6.
|
||
|
||
## Alternative Installs
|
||
### 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.
|
||
* `/sw` and `/opt/local` because build scripts get confused when
|
||
Homebrew is there instead of Fink or MacPorts, respectively.
|
||
|
||
However do yourself a favor and install to `/usr/local`. Some things may
|
||
not build when installed elsewhere. One of the reasons Homebrew just
|
||
works relative to the competition is **because** we recommend installing
|
||
to `/usr/local`. *Pick another prefix at your peril!*
|
||
|
||
`mkdir homebrew && curl -L https://github.com/Homebrew/homebrew/tarball/master | tar xz --strip 1 -C homebrew`
|
||
|
||
### Untar anywhere and then symlink the `brew` command elsewhere
|
||
You can also install Homebrew into e.g.
|
||
`~/Developer` and then symlink the brew command into `/usr/local/bin`.
|
||
|
||
Everything will install into `~/Developer`, but your
|
||
brew command is still in the path. **NOTE** that Homebrew will still
|
||
need to create symlinks into `/usr/local` or nothing will
|
||
work! But the actual files are installed to
|
||
`~/Developer/Cellar`.
|
||
|
||
### 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 `/usr/local` and tweaked formulae for development in `~/homebrew`.
|
||
|
||
### Ignoring SSL certificate errors (not recommended)
|
||
The instructions on the homepage use `curl` to download a Ruby script
|
||
from GitHub over HTTPS. Older versions of OS X may not have the necessary CA
|
||
certificates to verify GitHub's SSL certificate. In that case, you can
|
||
add `--insecure` to the `curl` command, forcing `curl` to ignore SSL certificate errors.
|
||
This will leave your connection to GitHub vulnerable to MITM, and is <strong>not recommended</strong>.
|
||
You may consider updating your CA certificates instead.
|
||
|
||
## Uninstallation
|
||
Uninstallation is documented in the [FAQ](FAQ.md).
|
||
|
||
<a name="1"><sup>1</sup></a> Not all formulae have CPU or OS requirements, but you can assume
|
||
you will have trouble if you don’t conform. Also, you can find
|
||
PowerPC and Tiger branches from other users in the fork network. See
|
||
[Interesting Taps & Branches](Interesting-Taps-&-Branches.md).
|
||
|
||
<a name="2"><sup>2</sup></a> 10.7 or higher is recommended. 10.6 is supported on a
|
||
best-effort basis. For 10.4 and 10.5, 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 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](http://brew.sh) requires a Bourne-compatible shell (e.g.
|
||
bash or zsh). Notably, fish, tcsh and csh will not work.
