使用國內的鏡像替換homebrew鏡像，對鏡像進行加速源
原先我們執行brew命令安裝的時候，跟3個倉庫地址有關
1 brew.git
2 homebrew-core.git
3 homebrew-bottles
把三個倉庫地址全部替換成國內Alibaba提供的地址

3.1 這個步驟跟你的macOs系統使用的shell版本有關系，首先查看shell版本

>> ~/.zshrc
source ~/.zshrc
#=======================================================
# 還原為官方提供的 homebrew-bottles 訪問地址
vi ~/.zshrc
# 然后，刪除 HOMEBREW_BOTTLE_DOMAIN 這一行配置
source ~/.zshrc

mac下安裝和使用brew
一，安裝brew
1，安裝brew
curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local –strip 1
2，安裝完成后執行
brew
提示：Please run brew update!
3，按照提示更新，執行
brew update
報錯：Error: /usr/local must be writable!
4，賦給/usr/local目錄權限，執行sudo chown -R $(whoami) /usr/local，即
sudo chown -R fxp /usr/local
其中fxp為系統當前用戶名。
5，再次執行
brew update
提示：
remote: Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
HEAD is now at c3f959d Merge pull request #1542 from woodruffw/deprecate-utils-json
To restore the stashed changes to /usr/local run:
‘cd /usr/local && Git stash pop’

Error: Could not link:

Please delete these paths and run brew update.
==> Migrated HOMEBREW_REPOSITORY to /usr/local/Homebrew!
Homebrew no longer needs to have ownership of /usr/local. If you wish you can
return /usr/local to its default ownership with:
sudo chown root:wheel /usr/local
6，按照提示刪除/usr/local/share/doc/homebrew，執行
rm -r -f /usr/local/share/doc/homebrew
7，再次執行
brew update
安裝更新成功！
二，使用brew
命令行下執行brew，用法提示如下：
Example usage:
brew search [TEXT|/REGEX/]
brew (info|home|options) [FORMULA…]
brew install FORMULA…
brew update
brew upgrade [FORMULA…]
brew uninstall FORMULA…
brew list [FORMULA…]
Troubleshooting:
brew config
brew doctor
brew install -vd FORMULA
Developers:
brew create [URL [–no-fetch]]
brew edit [FORMULA…]
https://github.com/Homebrew/brew/blob/master/docs/Formula-Cookbook.md
Further help:
man brew
brew help [COMMAND]
brew home
常用命令有安裝和卸載等，以安裝和卸載autojump為例：
安裝：sudo brew install autojump
卸載：sudo brew uninstall wget
查看安裝軟件的話，命令如下：
sudo brew search /apache*/
注意/apache*/是使用的正則表達式，用/分割。

前言：想學習一下Erlang,想通過homebrew安裝一下環境，才發現新電腦還沒有安裝。通過官方命令在終端上安裝時，發現小水管實在無法讓人忍受。
於是只能通過國內鏡像來安裝啦，中間也遇到點問題下面把過程記錄一下。
下面使用 清華鏡像
1.通過編輯install文件來使用鏡像地
1.1獲取brew_install
curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install >> brew_instal
1.2編輯brew_instal
vim brew_instal
1.3在Vim模式下，按i，進入編輯模式，在BREW_REPO和CORE_TAP_REPO前加#注釋掉，寫入鏡像地址代替
BREW_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git".freeze
CORE_TAP_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git".freeze
1.4按ESC退出編輯模式，輸入:wq Return保存退出
2安裝
2.1安裝,運行install
/usr/bin/ruby ~/brew_install
2.2 出現如下代碼時，不用等了，直接關掉命令窗口
==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...
2.3進入下面的 Taps 目錄，clone homebrew-core
cd /usr/local/Homebrew/Library/Taps/homebrew
git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
3把homebrew repo切換為清華鏡像
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
brew update
4 這時，終端會顯示Already up-to-date.到此，homebrew就安裝完畢了，我可以去安裝Erlang啦

~/.cocoapods/repos/master重裝
第一步：sudo rm -fr ~/.cocoapods/repos/master
第二步：git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
第三步：pod repo update
