Mac OSX系統homebrew update Fetching failed問題解決方案

1. brew update error

(i) 問題出現及現象描述

昨天換了台電腦，有些軟體需要重新安裝或更新一下，遇到了下面的問題

cv@xys-MacBook-Pro ~ % brew update
touch: /usr/local/Homebrew/.git/FETCH_HEAD: Permission denied
error: cannot open .git/FETCH_HEAD: Permission denied
touch: /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/.git/FETCH_HEAD: Permission denied

Already up-to-date.

(ii) 解決方案

在***上找到了一個類似的問題，用高贊的回答解決了這個問題。

直接通過改變 /usr/local 的所屬使用者進而解決權限問題。

不同的版本使用的指令略有不同，如果是 macOS High Sierra 或更高版本的系統的使用者，使用下面的指令可以修改所屬權，

~$ sudo chown -R $(whoami) $(brew --prefix)/*

如果是 macOS Sierra 或更低版本的系統的使用者，使用下面的指令

~$ sudo chown -R $(whoami) /usr/local

檢視本機系統版本資訊，可以通過單擊左上角蘋果 Logo ==> 關于本機，就能看到系統版本号及其名稱。版本号之間的高低可以通過WikiPedia上面記載的版本與名稱對應清單來查詢。

2. brew update "Fetching homebrew-cask failed!"

(i) 問題描述

盡管權限問題用上述方法解決了，但後續執行時又遇到了一點問題，這次是主要是Homebrew的其中兩個組成部分

homebrew-cask

和

homebrew-core

引起的，出現了如下所示的 "Fetching failed" 錯誤。

cv@xys-MBP ~ % brew update
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask failed!
Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core failed!
Updated 2 taps (homebrew/cask and caskroom/cask).

(ii) 解決方案

嘗試了一些方法都沒解決，最後選擇重新安裝 Homebrew，畢竟沒有什麼問題是重裝不能解決的，如過有，就連系統一起重裝...話說回來，重裝之後确實沒有問題了（\汗）。

首先自然是解除安裝已有的安裝版本，指令是

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

，結果如下。

cv@xys-MBP ~ % /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
Warning: The Ruby Homebrew uninstaller is now deprecated and has been rewritten in
Bash. Please migrate to the following command: 
  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to raw.githubusercontent.com:443

cv@xys-MBP ~ % /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)

接着當然是安裝新版本，指令是

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

，結果如下，中間有一次需要根據自己的需求選擇源并輸入 root 密碼。

cv@xys-MBP ~ % /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

請選擇一個下載下傳鏡像，例如中科大，輸入1回車。
源有時候不穩定，如果git克隆報錯重新運作腳本選擇源。cask非必須，有部分人需要。
1、中科大下載下傳源 2、清華大學下載下傳源 3、北京外國語大學下載下傳源  4、騰訊下載下傳源（不推薦） 5、阿裡巴巴下載下傳源(不推薦 缺少cask源)

請輸入序号:

我選擇了中科大下載下傳源，輸入 1 回車即可。

你選擇了中國科學技術大學下載下傳源

！！！此腳本将要删除之前的brew(包括它下載下傳的軟體)，請自行備份。
->是否現在開始執行腳本（N/Y）

是否執行，選擇是，輸入 Y 回車繼續。接着輸入密碼後正常情況下就能一直運作到最後了，如果中間斷了根據提示進行相應的操作即可。

--> 腳本開始執行
 Mac os設定開機密碼方法：
  (設定開機密碼：在左上角蘋果圖示->系統偏好設定->使用者與群組->更改密碼)
  (如果提示This incident will be reported. 在使用者與群組中檢視是否管理者)
==> 通過指令删除之前的brew、建立一個新的Homebrew檔案夾
請輸入開機密碼，輸入過程不顯示，輸入完後回車

Brew自動安裝程式運作完成
國内位址已經配置完成

  桌面的Old_Homebrew檔案夾，大緻看看沒有你需要的可以删除。

初步介紹幾個brew指令
本地軟體庫清單：brew ls
查找軟體：brew search google（其中google替換為要查找的關鍵字）
檢視brew版本：brew -v  更新brew版本：brew update
安裝cask軟體：brew install --cask firefox 把firefox換成你要安裝的

歡迎右鍵點選下方位址-打開URL 來給點個贊
https://zhuanlan.zhihu.com/p/111014448 

 重新開機終端 或者 運作 source /Users/cv/.zprofile   否則可能無法使用

安裝完成後按照提示運作 source 指令

cv@xys-MBP ~ % source ~/.zprofile

至此重裝過程結束，開始正常使用 Homebrew。
