在使用mac作为开发工具的时候，经常需要安装各种工具软件，一个一个下载很不方便，使用homebrew进行安装方便快捷。

在使用homebrew安装软件之前，需要先安装homebrew，但是按照官网的方法，似乎安装不了。

homebrew官网: https://brew.sh/

官网推荐的方法是： 在mac的控制台输入命令进行安装：

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

但是可能会出现等待很长时间，也无法安装的情况。

可以采用下面的方法：

1. 在 Finder 里面找到一个容易找到的路径（比如Download目录下面），创建一个文本文件，命名为install_brew.sh。然后打开该文件，将下面的内容复制进去。

#!/bin/bash set -u # First check if the OS is Linux. if [[ "$(uname)" = "Linux" ]]; then HOMEBREW_ON_LINUX=1 fi # Check if macOS is ARM if [[ "$(uname -m)" = "arm64" ]] && [[ "$(uname)" = "Darwin" ]]; then HOMEBREW_APPLE_SILICON=1 fi # On macOS, this script installs to /usr/local only. # On Linux, it installs to /home/linuxbrew/.linuxbrew if you have sudo access # and ~/.linuxbrew otherwise. # To install elsewhere (which is unsupported) # you can untar https://github.com/Homebrew/brew/tarball/master # anywhere you like. if [[ -z "${HOMEBREW_ON_LINUX-}" ]]; then HOMEBREW_PREFIX="/usr/local" HOMEBREW_REPOSITORY="/usr/local/Homebrew" HOMEBREW_CACHE="${HOME}/Library/Caches/Homebrew" STAT="stat -f" CHOWN="/usr/sbin/chown" CHGRP="/usr/bin/chgrp" GROUP="admin" TOUCH="/usr/bin/touch" else HOMEBREW_PREFIX_DEFAULT="/home/linuxbrew/.linuxbrew" HOMEBREW_CACHE="${HOME}/.cache/Homebrew" STAT="stat --printf" CHOWN="/bin/chown" CHGRP="/bin/chgrp" GROUP="$(id -gn)" TOUCH="/bin/touch" fi BREW_REPO="https://github.com/Homebrew/brew" # TODO: bump version when new macOS is released MACOS_LATEST_SUPPORTED="10.15" # TODO: bump version when new macOS is released MACOS_OLDEST_SUPPORTED="10.13" # For Homebrew on Linux REQUIRED_RUBY_VERSION=2.6 # https://github.com/Homebrew/brew/pull/6556 REQUIRED_GLIBC_VERSION=2.13 # https://docs.brew.sh/Homebrew-on-Linux#requirements # no analytics during installation export HOMEBREW_NO_ANALYTICS_THIS_RUN=1 export HOMEBREW_NO_ANALYTICS_MESSAGE_OUTPUT=1 # string formatters if [[ -t 1 ]]; then tty_escape() { printf "\033[%sm" "$1"; } else tty_escape() { :; } fi tty_mkbold() { tty_escape "1;$1"; } tty_underline="$(tty_escape "4;39")" tty_blue="$(tty_mkbold 34)" tty_red="$(tty_mkbold 31)" tty_bold="$(tty_mkbold 39)" tty_reset="$(tty_escape 0)" have_sudo_access() { local -a args if [[ -n "${SUDO_ASKPASS-}" ]]; then args=("-A") fi if [[ -z "${HAVE_SUDO_ACCESS-}" ]]; then if [[ -n "${args[*]-}" ]]; then /usr/bin/sudo "${args[@]}" -l mkdir &>/dev/null else /usr/bin/sudo -l mkdir &>/dev/null fi HAVE_SUDO_ACCESS="$?" fi if [[ -z "${HOMEBREW_ON_LINUX-}" ]] && [[ "$HAVE_SUDO_ACCESS" -ne 0 ]]; then abort "Need sudo access on macOS (e.g. the user $USER to be an Administrator)!" fi return "$HAVE_SUDO_ACCESS" } shell_join() { local arg printf "%s" "$1" shift for arg in "$@"; do printf " " printf "%s" "${arg// /\ }" done } chomp() { printf "%s" "${1/"$'\n'"/}" } ohai() { printf "${tty_blue}==>${tty_bold} %s${tty_reset}\n" "$(shell_join "$@")" } warn() { printf "${tty_red}Warning${tty_reset}: %s\n" "$(chomp "$1")" } abort() { printf "%s\n" "$1" exit 1 } execute() { if !

2. 然后打开控制台，找到 install_brew.sh 这个文件。（例如这个文件的路径是: /User/用户名/Downloads/install_brew.sh），执行下面的命令。

cd /User/用户名/Downloads

./install_brew.sh

3. 等待安装完成即可。
