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
