mac之homebrew安裝

經過homebrew能夠管理衆多開源軟件的安裝和卸載。使用homebrew能夠很是容易的安裝 os x中沒有包含的unix工具包和語言包，好比wget;node;lua;rabbitmq;nginx等

 

安裝

1.在終端運行命令

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

第一次安裝提示信息：

localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

==> This script will install:

/usr/local/bin/brew

xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.

/usr/local/Homebrew

==> The following new directories will be created:

/usr/local/Cellar

/usr/local/Homebrew

/usr/local/Frameworks

/usr/local/bin

/usr/local/etc

/usr/local/include

/usr/local/lib

/usr/local/opt

/usr/local/sbin

/usr/local/share

/usr/local/share/zsh

/usr/local/share/zsh/site-functions

/usr/local/var

 

Press RETURN to continue or any other key to abort

 

當執行到 fatal: unable to access 'https://github.com/Homebrew/brew/': Failed to connect to github.com port 443: Operation timed out

 

2.好吧，既然沒有安裝成功（可能有臨時文件）那就卸載乾淨從新安裝唄

執行卸載命令：

localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

奶奶的，說什麼沒有找到改軟件

Failed to locate Homebrew!

 

3.你既然說沒有找到該軟件（就是沒有安裝唄），那就再次執行安裝命令唄

localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

火大了！！！ 又提示我已經安裝過啦 哼哼哼～

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 etc Frameworks Homebrew include lib opt sbin share var

 

4.沒辦法啊，去卸載乾淨再來吧。喪～

網上各類命令卸載都很差使，既然有安裝的臨時文件，那就各類刪除臨時文件。

依第一次安裝新建的文件夾住要刪除Cellar ; Frameworks ; Homebrew此三個文件

---> local ls -al

rm -rf Cellar Frameworks Homebrew

注：文件夾可能刪除不了報「權限拒絕訪問」 ， 查看筆記命令（經常使用）

5.再次安裝

localhost:~ bobo$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

-e:82: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

==> This script will install:

/usr/local/bin/brew

/usr/local/share/doc/homebrew

/usr/local/share/man/man1/brew.1

/usr/local/share/zsh/site-functions/_brew

/usr/local/etc/bash_completion.d/brew

/usr/local/Homebrew

==> The following new directories will be created:

/usr/local/Cellar

/usr/local/Homebrew

/usr/local/Frameworks

 

Press RETURN to continue or any other key to abort

 

此次安裝只新建了3個文件夾，就是以前刪除的那三個。

繼續往下執行，最後出現下面的提示表示安裝成功

==> Installation successful!

==> Next steps

Run `brew help` to get started

執行brew help ， 正常顯示命令幫助，nice。
