树莓派安装Homebrew全过程

首先，各大Linux官方一般都有自己的包管理器，一般首选官方的包管理器。

安装一些依赖：sudo apt install ruby build-essential

官方的给出的一键安装命令：

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

此时很可能出现错误：curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused

如果官方安装太慢或者出现这个错误按照下文的操作！

官方的安装太慢，我们可以更改安装源为国内的源（我更改的是国内的清华源）。接下来将一步步讲解。

1. 下载安装检查脚本：

   • 如果有wget，可以尝试使用wget下载：

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

     如果出现错误：

     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.
     

     请使用下面的方法！

   • 直接使用浏览器打开链接https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh，看到的内容全部复制下来，创建一个文件命名为install.sh，把复制的内容全部粘贴再这里面。

2. 更改安装检查脚本：

   在安装检查脚本里面有一行：

   exec ruby -e "`curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install`" "[email protected]"
   

   我们需要更改为：

   exec ruby "install_linux.rb" "[email protected]"
   

3. 下载安装文件：

   • 如果有wget，可以尝试使用wget下载：

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

     如果出现错误：

     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.
     

     请使用下面的方法！

   • 直接使用浏览器打开链接https://raw.githubusercontent.com/Linuxbrew/install/master/install，看到的内容全部复制下来，创建一个文件命名为install_linux.rb，把复制的内容全部粘贴再这里面。

4. 更改安装文件：

   修改官方文件里面的源：

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

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

接下来给安装检查文件加上执行权限：chmod +x install.sh，然后执行./install.sh

等待安装，不出意外就会看见：

==> 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'...

下载仓库的地址在国外，下载会比较慢，我们可以手动下载。

首先使用组合键CTRL+C关闭安装过程，

创建目录:

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

进入目录:

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

然后执行：

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

回到原来目录：cd -

再次执行：./install.sh

执行后会提示：

- 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.

如果出现了这个Warning则需要手动进行一些操作：

如果是bash用户：

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

如果是zsh用户：

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

重启一下或者直接在命令行执行：eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)，就可以正常使用brew。

使用过程中更换为国内的源使用起来更加舒适

更换brew的源为清华源：

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镜像：

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

长期更改：

• bash用户

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

• zsh用户

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