【macOS】mac M2 安装 Homebrew & nvm

gitee 快速安装

打开终端，复制如下命令，按回车执行(需要输入密码)

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

在这个过程中可能还会弹出安装 git 的提示，直接安装等待即可

然后再次输入上面的命令，输入1选择清华源就开始安装了

在本文发布之时，这个方法安装后会出现报错 – ruby 版本过老

所以这个方法暂时不行，后面如果这个问题被解决了这个也是一个很省事的安装方法

官网安装

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

不过这个方法也会出现问题—无法连接 github (开了代理也会报错)，后面我也就放弃了

中科院镜像安装

参考地址
首先，需要确保系统中安装了 bash、git 和 curl，对于 macOS 用户需额外要求安装 Command Line Tools (CLT) for Xcode。

在命令行输入 xcode-select --install 安装 CLT for Xcode 即可(自带有)。

接着，在终端输入以下几行命令设置环境变量：

export HOMEBREW_INSTALL_FROM_API=1
export HOMEBREW_API_DOMAIN="https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/api"
export HOMEBREW_BOTTLE_DOMAIN="https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles"
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"

最后，在终端运行以下命令以安装 Homebrew

# 从本镜像下载安装脚本并安装 Homebrew / Linuxbrew
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

安装成功后需将 brew 程序的相关路径加入到环境变量中：
以下针对基于 Apple Silicon CPU 设备上的 macOS 系统（命令行运行 uname -m 应输出 arm64）上的 Homebrew：

test -r ~/.bash_profile && echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.bash_profile
test -r ~/.zprofile && echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile

对基于 Intel CPU 设备上的 macOS 系统（命令行运行 uname -m 应输出 x86_64）的用户可跳过本步。

brew 安装 nvm

brew install nvm

# 将出现
You should create NVM's working directory if it doesn't exist:

  mkdir ~/.nvm

Add the following to ~/.zshrc or your desired shell
configuration file:

  export NVM_DIR="$HOME/.nvm"
 [ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && . "/opt/homebrew/opt/nvm/nvm.sh" # This loads nvm
 [ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && . "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion

You can set $NVM_DIR to any location, but leaving it unchanged from
/usr/local/opt/nvm will destroy any nvm-installed Node installations
upon upgrade/reinstall.

Type `nvm help` for further information.

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d
==> Summary
  /usr/local/Cellar/nvm/0.35.3: 7 files, 150.0KB, built in 2 seconds

安装完成后根据其提示

# 创建 nvm 目录
mkdir ~/.nvm

# 编辑 ~/.zshrc 配置文件
vi ~/.zshrc

# 添加以下内容：
export NVM_DIR="$HOME/.nvm"
 [ -s "/opt/homebrew/opt/nvm/nvm.sh" ] && . "/opt/homebrew/opt/nvm/nvm.sh" # This loads nvm
 [ -s "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" ] && . "/opt/homebrew/opt/nvm/etc/bash_completion.d/nvm" # This loads nvm bash_completion

# 立即生效
source ~/.zshrc

# 检查是否配置成功
echo $NVM_DIR
# 出现下面内容就算成功了
/Users/your-username/.nvm
