 最后，在终端运行以下命令以安装 Homebrew/Linuxbrew：
 
 ```bash
-# 从 GitHub 获取安装脚本，并修改其中的仓库源，运行以安装 Homebrew/Linuxbrew
+# 从本镜像下载安装脚本，修改其中的仓库源并安装 Homebrew/Linuxbrew
+git clone --depth=1 https://{{ site.hostname }}/git/homebrew/install.git brew-install
+/bin/bash -c "$(sed 's|^BREW_REPO=.*$|BREW_REPO="https://{{ site.hostname }}/git/homebrew/brew.git"|g' brew-install/install.sh)"
+rm -rf brew-install
+
+# 也可从 GitHub 获取官方安装脚本，修改其中的仓库源，运行以安装 Homebrew/Linuxbrew
 /bin/bash -c "$(
 	curl -fsSL https://github.com/Homebrew/install/raw/master/install.sh |
 	sed 's|^BREW_REPO=.*$|BREW_REPO="https://{{ site.hostname }}/git/homebrew/brew.git"|g'
 )"
-
-# 若以上命令遇到网络问题，则从本镜像下载安装脚本并安装 Homebrew/Linuxbrew
-git clone --depth=1 https://{{ site.hostname }}/git/homebrew/install.git brew-install
-/bin/bash -c "$(sed 's|^BREW_REPO=.*$|BREW_REPO="https://{{ site.hostname }}/git/homebrew/brew.git"|g' brew-install/install.sh)"
-rm -rf brew-install
 ```
 
 这样在首次安装的时候也可以使用镜像。
