mac之homebrew安装

通过homebrew可以管理众多开源软件的安装和卸载。使用homebrew可以非常容易的安装 os x中没有包含的unix工具包和语言包，比如wget;node;lua;rabbitmq;nginx等   安装 1.在终端运行命令 ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 第一次安装提示信息： localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" ==> This script will install: /usr/local/bin/brew xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools. /usr/local/Homebrew ==> The following new directories will be created: /usr/local/Cellar /usr/local/Homebrew /usr/local/Frameworks /usr/local/bin /usr/local/etc /usr/local/include /usr/local/lib /usr/local/opt /usr/local/sbin /usr/local/share /usr/local/share/zsh /usr/local/share/zsh/site-functions /usr/local/var   Press RETURN to continue or any other key to abort   当执行到fatal: unable to access 'https://github.com/Homebrew/brew/': Failed to connect to github.com port 443: Operation timed out   2.好吧，既然没有安装成功（可能有临时文件）那就卸载干净重新安装呗 执行卸载命令： localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" 奶奶的，说什么没有找到改软件 Failed to locate Homebrew!   3.你既然说没有找到该软件（就是没有安装呗），那就再次执行安装命令呗 localhost:~ bobo$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" 火大了！！！ 又提示我已经安装过啦 哼哼哼～ It appears Homebrew is already installed. If your intent is to reinstall you should do the following before running this installer again: ruby -e "$(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.没办法啊，去卸载干净再来吧。丧～ 网上各种命令卸载都不好使，既然有安装的临时文件，那就各种删除临时文件。 依第一次安装新建的文件夹住要删除Cellar ; Frameworks ; Homebrew此三个文件 ---> local ls -al rm -rf Cellar Frameworks Homebrew 注：文件夹可能删除不了报“权限拒绝访问” ， 查看笔记命令（常用） 5.再次安装 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   这次安装只新建了3个文件夹，就是之前删除的那三个。 继续往下执行，最后出现下面的提示表示安装成功 ==> Installation successful! ==> Next steps Run `brew help` to get started Further documentation: https://git.io/brew-docs ==> Homebrew has enabled anonymous aggregate user behaviour analytics Read the analytics documentation (and how to opt-out) here: https://git.io/brew-analytics   执行brew help ， 正常显示命令帮助，nice。
