只是想在 Mac 上用 wget

写在前面

最开始只是想在 Mac 上用 wget 方便下载东西，无奈得特意安装。所以先装了 homebrew 再装 wget。
按道理来讲，homebrew 本身非常方便，无奈墙人所难。所以需要用镜像安装和配置 homebrew，再安装 wget 就很方便了。

安装 homebrew

原本命令超级简单，但是下载不下来呢……所以需要镜像，这样就很方便了。

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

代码摘录：

xcode-select --install
export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"
export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles"

git clone --depth=1 https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/install.git brew-install
/bin/bash brew-install/install.sh
rm -rf brew-install

export HOMEBREW_BREW_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git"
brew update

export HOMEBREW_CORE_GIT_REMOTE="https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git"

brew update

安装 wget

首先 update，很好上来就失败了呢😄

brew update
# error: Not a valid ref: refs/remotes/origin/master
# fatal: Could not resolve HEAD to a revision
# Already up-to-date.

看一下具体节点吧

brew update --verbose
# balabalabala
# Updating /opt/homebrew/Library/Taps/homebrew/homebrew-core...
# fatal: Could not resolve HEAD to a revision

去到这个路径下面看一看

cd /opt/homebrew/Library/Taps/homebrew/homebrew-core
ls -al
git fetch --prune origin
git pull --rebase origin master
# pulling
# From https://mirrors.ustc.edu.cn/homebrew-core
#  * branch                  master     -> FETCH_HEAD
# 成功之后，就可以 brew update，然后再装 wget 或者其他包包
brew update
brew install wget
