0 Homebrew是啥？

“Homebrew installs the stuff you need that Apple didn’t.——Homebrew 使 OS X 更完整”。

Homebrew的官网​​[1]​​（多语言版本）简单明了地介绍了如何安装和使用这个工具，并提供了自己的Wiki。



1 安装Homebrew

brew的安装很简单，使用一条ruby命令即可，Mac系统上已经默认安装了ruby。


gerryyang@mba:bin$ruby --version

ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]


关于安装brew的详细说明可以参考其github上的wiki说明​​[2]​​：

"

Installation


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

The standard script installs Homebrew to ​​/usr/local​​​ so that ​​you don’t need sudo​​​ when you​​brew install​​​. It is acareful script, it can be run even if you have stuff installed to​​/usr/local​​ already. It tells you exactly what it will do before itdoes it too. And you have to confirm everything it will do before itstarts.

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

"



  2. gerryyang@mba:~$ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
  3. It appears Homebrew is already installed. If your intent is to reinstall you
  4. should do the following before running this installer again:

  6. rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup



由于我的系统上已经安装过brew，因此再次执行安装命令会提示我brew已经存在。

3 Homebrew的有趣问题

下面关于Homebrew的一些常见问题​​[3]​​：

(1) 在OS X中找不到想要的软件，可以使用brew安装；




  2. gerryyang@mba:~$brew install wget
  3. ==> Downloading http://ftpmirror.gnu.org/wget/wget-1.14.tar.gz
  4. ######################################################################## 100.0%
  5. ==> ./configure --prefix=/usr/local/Cellar/wget/1.14 --sysconfdir=/usr/local/etc
  6. ==> make install
  7. Warning: Could not link wget. Unlinking...
  8. Error: The `brew link` step did not complete successfully
  9. The formula built, but is not symlinked into /usr/local
  10. You can try again using `brew link wget'

  12. Possible conflicting files are:
  13. /usr/local/bin/wget
  14. /usr/local/share/man/man1/wget.1
  15. ==> Summary
  16. <span style="font: 13.0px Monaco">/usr/local/Cellar/wget/1.14: 8 files, 688K, built in 2.3 minutes</span>


由于之前使用源码方式安装过wget，因此再用brew安装时会提示冲突的错误，因为/usr/locat/bin/wget已经存在。实际上，Homebrew 将软件包分装到单独的目录（/usr/local/Cellar），然后 symlink 到 /usr/local 中。 


(2) 如何更新本地已安装的package呢？


第一步：先更新brew：

brew update



  2. gerryyang@mba:bin$brew update
  3. Already up-to-date.



第二步：更新所有package：

brew upgarde




  2. gerryyang@mba:bin$brew upgrade
  3. ==> Upgrading 1 outdated package, with result:
  4. wget 1.15
  5. ==> Upgrading wget
  6. ==> Installing wget dependency: openssl
  7. ==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/openssl-1.0
  8. ######################################################################## 100.0%
  9. ==> Pouring openssl-1.0.1f.mavericks.bottle.tar.gz
  10. ==> Caveats
  11. This formula is keg-only, so it was not symlinked into /usr/local.

  13. Mac OS X already provides this software and installing another version in
  14. parallel can cause all kinds of trouble.

  16. The OpenSSL provided by OS X is too old for some software.

  18. Generally there are no consequences of this for you. If you build your
  19. own software and it requires this formula, you'll need to add to your
  20. build variables:

  22. LDFLAGS: -L/usr/local/opt/openssl/lib
  23. CPPFLAGS: -I/usr/local/opt/openssl/include

  25. ==> security find-certificate -a -p /Library/Keychains/System.keychain > '/usr/l
  26. ==> security find-certificate -a -p /System/Library/Keychains/SystemRootCertific
  27. ==> mv -f /usr/local/etc/openssl/osx_cert.pem.tmp /usr/local/etc/openssl/osx_cer
  28. ==> Summary
  29. /usr/local/Cellar/openssl/1.0.1f: 429 files, 15M
  30. ==> Installing wget
  31. ==> Downloading http://ftpmirror.gnu.org/wget/wget-1.15.tar.gz
  32. ######################################################################## 100.0%
  33. ==> ./configure --prefix=/usr/local/Cellar/wget/1.15 --sysconfdir=/usr/local/etc --with-ssl=openssl --with-libssl-prefix=/usr/local/opt/openssl --disable-iri
  34. ==> make install
  35. Warning: Could not link wget. Unlinking...
  36. Error: The `brew link` step did not complete successfully
  37. The formula built, but is not symlinked into /usr/local
  38. You can try again using `brew link wget'

  40. Possible conflicting files are:
  41. /usr/local/bin/wget
  42. /usr/local/share/man/man1/wget.1
  43. ==> Summary
  44. /usr/local/Cellar/wget/1.15: 8 files, 700K, built in 73 seconds
  45. gerryyang@mba:bin$



(3) 如何删除Homebrew？


If you installed to ​​/usr/local​​​ then you can use the script in ​​thisgist​​​ to uninstall — it will onlyremove Homebrew and the stuff Homebrew installed leaving anything elsein​​/usr/local​​ alone.

Provided you haven’t put anything else in Homebrew’s prefix(​​brew --prefix​​​), you can generally just​​rm -rf​​ that directory. Thisis because Homebrew won’t touch files outside its prefix.


(4) Homebrew下载的package存放的路径在哪里？




  2. gerryyang@mba:bin$brew --cache
  3. /Library/Caches/Homebrew
  4. gerryyang@mba:bin$ls /Library/Caches/Homebrew/
  5. Formula/ wget-1.14.tar.gz
  6. coreutils-8.22.tar.xz wget-1.15.tar.gz
  7. openssl-1.0.1f.mavericks.bottle.tar.gz xz-5.0.5.mavericks.bottle.2.tar.gz
  8. gerryyang@mba:bin$ls /Library/Caches/Homebrew/Formula/
  9. coreutils.brewing openssl.brewing wget.brewing xz.brewing

  11. gerryyang@mba:bin$



(5) 我可以安装自己的stuff在/usr/local吗？

Yes, brew is designed to not get in your way so you can use it how youlike.

Install your own stuff, but be aware that if you install commonlibraries, like libexpat yourself, it may cause trouble when trying tobuild certain Homebrew formula. As a result​​brew doctor​​ will warn youabout this.

Thus it’s probably better to install your own stuff to the Cellar andthen ​​brew link​​ it. 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 foo Linking /usr/local/Cellar/foo/0.1… 17 symlinks created

在我的环境上检测是这样的：




  2. gerryyang@mba:bin$brew doctor
  3. Warning: Unbrewed dylibs were found in /usr/local/lib.
  4. If you didn't put them there on purpose they could cause problems when
  5. building Homebrew formulae, and may need to be deleted.

  7. Unexpected dylibs:
  8. /usr/local/lib/libboost_atomic.dylib
  9. /usr/local/lib/libboost_chrono.dylib

  34. /usr/local/lib/libboost_wave.dylib
  35. /usr/local/lib/libboost_wserialization.dylib

  37. Warning: Unbrewed static libraries were found in /usr/local/lib.
  38. If you didn't put them there on purpose they could cause problems when
  39. building Homebrew formulae, and may need to be deleted.

  41. Unexpected static libraries:
  42. /usr/local/lib/libboost_atomic.a
  43. /usr/local/lib/libboost_chrono.a
  44. /usr/local/lib/libboost_context.a

  64. /usr/local/lib/libboost_serialization.a
  65. /usr/local/lib/libboost_signals.a
  66. /usr/local/lib/libboost_system.a
  67. /usr/local/lib/libboost_test_exec_monitor.a
  68. /usr/local/lib/libboost_thread.a

  71. /usr/local/lib/libboost_wave.a
  72. /usr/local/lib/libboost_wserialization.a

  74. Warning: You have unlinked kegs in your Cellar
  75. Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
  76. those kegs to fail to run properly once built. Run `brew link` on these:

  78. wget
  79. gerryyang@mba:bin$





(6) 为什么选择Homebrew这个名字？

mxcl was too concerned with the beer theme and didn’t consider that the project may actually prove popular. By the time he realized it was too late. However, today, the first google hit for “homebrew” is not beer related ;-)

看来作者是个酒鬼！
