For detailed instructions on installing brew, refer to the wiki instructions on GitHub [2]:

Installation

The suggested and easiest-to-install Homebrew is on the homepage. We don ' t duplicate it's here because it's asecurity risk to list it on a user-editable wiki.

The standard script installs Homebrew to/usr/localso this you don't need sudo when youbrew install. It is acareful script, the It can be run even if you have stuff installed To/usr/localalready. It tells exactly what it would do before itdoes it too. And you had to confirm everything it would do before itstarts.

There is other ways to the install Homebrew which provide you with moreflexibility. They is listed below the requirements.

"

1. Gerryyang@mba: ~ $ruby-E "$ (curl-fssl https://raw.github.com/Homebrew/homebrew/go/install)"
2. It appears Homebrew is already installed. If your intent is to reinstall you
3. Should do the following before running this installer again:
5. Rm-rf/usr/local/cellar/usr/local/.git && Brew Cleanup

Since brew is already installed on my system, executing the installation command again will prompt me that brew already exists.

3 Interesting questions about homebrew

Here are some common questions about homebrew [3]:

(1) In OS X cannot find the desired software, you can use the brew installation;

2. Gerryyang@mba: ~ $brew Install wget
4. ==> Downloading http://ftpmirror.gnu.org/wget/wget-1.14.tar.gz
6. ######################################################################## 100%
8. ==>./configure--prefix=/usr/local/cellar/wget/1.14--sysconfdir=/usr/local/etc
10. ==> make Install
12. Warning:could not link wget. Unlinking ...
14. Error:the ' Brew link ' step did not complete successfully
16. The formula built, but was not symlinked into/usr/local
18. You can try again using ' Brew link wget '
22. Possible conflicting files are:
24. /usr/local/bin/wget
26. /usr/local/share/man/man1/wget.1
28. ==> Summary
30. <span style= "font:13.0px Monaco" >/usr/local/cellar/wget/1.14:8 files, 688K, built in 2.3 minutes</span>

Since the wget was previously installed using the source code method, a conflicting error will be prompted with the brew installation because/usr/locat/bin/wget already exists. In fact, Homebrew the package into a separate directory (/usr/local/cellar) and then symlink to/usr/local.

(2) How do I update a locally installed package?

First step: Update Brew First:

Brew Update

1. [Email Protected]:bin$brew Update
2. Already up-to-date.

Step Two: Update all package:
Brew Upgarde

2. [Email protected]:bin$brew upgrade
4. ==> upgrading 1 Outdated package with result:
6. wget 1.15
8. ==> Upgrading wget
10. ==> Installing wget Dependency:openssl
12. ==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/openssl-1.0
14. ######################################################################## 100%
16. ==> Pouring openssl-1.0.1f.mavericks.bottle.tar.gz
18. ==> Caveats
20. This formula are keg-only, so it's not symlinked into/usr/local.
24. Mac OS X already provides this software and installing another version in
26. Parallel can cause all kinds of trouble.
30. The OpenSSL provided by OS X are too old for some software.
34. Generally there is no consequences of this. If You build your
36. Own software and it requires this formula, you'll need to the add to your
38. Build variables:
42. Ldflags:-l/usr/local/opt/openssl/lib
44. Cppflags:-i/usr/local/opt/openssl/include
48. ==> security find-certificate-a-p/library/keychains/system.keychain > '/usr/l
50. ==> Security Find-certificate-a-p/system/library/keychains/systemrootcertific
52. ==> mv-f/usr/local/etc/openssl/osx_cert.pem.tmp/usr/local/etc/openssl/osx_cer
54. ==> Summary
56. /usr/local/cellar/openssl/1.0.1f:429 files, 15M
58. ==> Installing wget
60. ==> Downloading http://ftpmirror.gnu.org/wget/wget-1.15.tar.gz
62. ######################################################################## 100%

66. ==> make Install
68. Warning:could not link wget. Unlinking ...
70. Error:the ' Brew link ' step did not complete successfully
72. The formula built, but was not symlinked into/usr/local
74. You can try again using ' Brew link wget '
78. Possible conflicting files are:
80. /usr/local/bin/wget
82. /usr/local/share/man/man1/wget.1
84. ==> Summary
86. /usr/local/cellar/wget/1.15:8 files, 700K, built in seconds
88. [Email protected]:bin$

(3) How to delete homebrew?

If you installed to/usr/localthen your can use the script on Thisgist to uninstall-it would onlyremove Homebrew and the St Uff Homebrew installed leaving anything elsein/usr/localalone.

Provided haven ' t put anything else in Homebrew ' s prefix (brew--prefix), you can generally justrm-rfthat directory. Thisis because Homebrew won ' t touch files outside its prefix.

(4) Where is the path of the package stored by homebrew download?

1. [email protected]:bin$brew --cache  
2. /library/caches/homebrew  
3. [email protected]:bin$ls /library/caches/homebrew/  
4. formula/                                  wget-1.14.tar.gz  
5. coreutils-8.22.tar.xz                   wget-1.15.tar.gz  
6. openssl-1.0.1f.mavericks.bottle.tar.gz   xz-5.0.5.mavericks.bottle.2.tar.gz  
7. [email protected]:bin$ls /library/ caches/homebrew/formula/  
8. coreutils.brewing  openssl.brewing   wget.brewing  xz.brewing  
9.   
10. [email protected]:bin$   

(5) Can I install my own stuff in/usr/local?

Yes, Brew is designed-not get-in your-on-the-youlike.

Install your own stuff, but being aware that if you install commonlibraries, like libexpat yourself, it may cause trouble whe n trying tobuild certain Homebrew formula. As a resultbrew Doctorwill warn Youabout this.

Thus it ' s probably better to install your own stuff to the Cellar andthenbrew Linkit. Like so:

$ cd foo-0.1 $ brew diy./configure —prefix=/usr/local/Cellar/foo/0.1 $ ./configure —prefix=/usr/local/Cellar/foo/0.1 [snip] $ make && make install $ brew link fooLinking /usr/local/Cellar/foo/0.1… 17 symlinks created

Detection in my environment is like this:

2. [Email Protected]:bin$brew doctor
4. Warning:unbrewed dylibs were found in/usr/local/lib.
6. If you didn ' t put them there on purpose they could cause problems when
8. Building Homebrew formulae, and may need to be deleted.
12. Unexpected dylibs:

154. Wget
156. [Email protected]:bin$

(6) Why choose the name homebrew?
MXCL is too concerned with the beer theme and didn ' t consider, that the project may actually prove popular. By the time he realized it is too late. However, today, the first Google hit for "homebrew" are not beer related;-)

(7) For more QA can refer to Homebrew's wiki[4]

(8) Some common installation recommendations

1. [Email protected]:bin$brew list
