樹莓派安裝Homebrew全過程

首先，各大Linux官方一般都有自己的包管理器，一般首選官方的包管理器。

安裝一些依賴：sudo apt install ruby build-essential

官方的給出的一鍵安裝命令：

sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

此時很可能出現錯誤：curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

如果官方安裝太慢或者出現這個錯誤按照下文的操作！

官方的安裝太慢，我們可以更改安裝源爲國內的源（我更改的是國內的清華源）。接下來將一步步講解。

1. 下載安裝檢查腳本：

   • 如果有wget，可以嘗試使用wget下載：

     wget https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh -O install.sh
     

     如果出現錯誤：

     Resolving raw.githubusercontent.com (raw.githubusercontent.com)... 151.101.228.133
     Connecting to raw.githubusercontent.com (raw.githubusercontent.com)|151.101.228.133|:443... failed: Connection refused.
     

     請使用下面的方法！

   • 直接使用瀏覽器打開鏈接https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh，看到的內容全部複製下來，創建一個文件命名爲install.sh，把複製的內容全部粘貼再這裏面。

2. 更改安裝檢查腳本：

   在安裝檢查腳本里面有一行：

   exec ruby -e "`curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install`" "$@"
   

   我們需要更改爲：

   exec ruby "install_linux.rb" "$@"
   

3. 下載安裝文件：

   • 如果有wget，可以嘗試使用wget下載：

     wget https://raw.githubusercontent.com/Linuxbrew/install/master/install -O install_linux.rb
     

     如果出現錯誤：

     Resolving raw.githubusercontent.com (raw.githubusercontent.com)... 151.101.228.133
     Connecting to raw.githubusercontent.com (raw.githubusercontent.com)|151.101.228.133|:443... failed: Connection refused.
     

     請使用下面的方法！

   • 直接使用瀏覽器打開鏈接https://raw.githubusercontent.com/Linuxbrew/install/master/install，看到的內容全部複製下來，創建一個文件命名爲install_linux.rb，把複製的內容全部粘貼再這裏面。

4. 更改安裝文件：

   修改官方文件裏面的源：

   ​ 在BREW_REPO = "https://github.com/Homebrew/brew".freeze前加#號

   ​ 在下方加入一行：BREW_REPO = "https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git".freeze

接下來給安裝檢查文件加上執行權限：chmod +x install.sh，然後執行./install.sh

等待安裝，不出意外就會看見：

==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
  https://github.com/Homebrew/brew#donations
==> Tapping homebrew/core
Cloning into '/home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core'...

下載倉庫的地址在國外，下載會比較慢，我們可以手動下載。

首先使用組合鍵CTRL+C關閉安裝過程，

創建目錄:

mkdir /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew，

進入目錄:

cd /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew。

然後執行：

git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git
git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-fonts.git
git clone https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-drivers.git

回到原來目錄：cd -

再次執行：./install.sh

執行後會提示：

- Configure Homebrew in your ~/.profile by running
    echo 'eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)' >>~/.profile
- Add Homebrew to your PATH
    eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
- We recommend that you install GCC by running:
    brew install gcc
- Run `brew help` to get started
- Further documentation: 
    https://docs.brew.sh
Warning: /home/linuxbrew/.linuxbrew/bin is not in your PATH.

如果出現了這個Warning則需要手動進行一些操作：

如果是bash用戶：

• 編輯.profile或者.bash_profile，添加一行：eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

如果是zsh用戶：

• 編輯.zhcrc，添加一行eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

重啓一下或者直接在命令行執行：eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)，就可以正常使用brew。

使用過程中更換爲國內的源使用起來更加舒適

更換brew的源爲清華源：

git -C /home/linuxbrew/.linuxbrew/Homebrew remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
git -C /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-core remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
git -C /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-cask remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git
git -C /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-cask-fonts remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-fonts.git
git -C /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/homebrew/homebrew-cask-drivers remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask-drivers.git
brew update

更改bintray鏡像：

臨時更改：export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles

長期更改：

• bash用戶

  echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles' >> ~/.bash_profile
  source ~/.profile
  

• zsh用戶

  echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
  source ~/.zshrc
