前言

大家在 m1 silicon macos 下开发 flutter ios 问题一直很多，今天就来讲下 cocoapods 的安装问题。

特别是安装了新系统 Ventura 后直接安装 cocoapods 会报错。

问题分析

❯ ruby -v
ruby 2.6.10p210 (2022-04-12 revision 67958) [universal.x86_64-darwin22]

是 macos 系统化自带的 ruby 版本太低，导致 cocoapods 安装失败。

默认 ruby 是 v2 版本，直接 install cocoapods 会报错的。

步骤

安装或者升级 Homebrew 包管理工具
安装全新的 Ruby 新版本
设置你的系统配置 ~/.bash_profile 或者 ~/.zshrc 文件
安装 cocopod

正文

1. 安装升级 Homebrew 包管理工具

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

# 升级
brew upgrade

2. 安装 ruby

brew install ruby

输出

==> Summary
/usr/local/Cellar/ruby/3.1.3: 16,149 files, 41.6MB
==> Running `brew cleanup ruby`...
Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
==> Caveats
==> ruby
By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/3.1.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH, run:
  echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

For compilers to find ruby you may need to set:
  export LDFLAGS="-L/usr/local/opt/ruby/lib"
  export CPPFLAGS="-I/usr/local/opt/ruby/include"

For pkg-config to find ruby you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"

装完完之后是 v3 版本的 ruby

3. 配置环境变量

vi ~/.bash_profile

# ruyb
# intel 芯片
if [ -d "/usr/local/opt/ruby/bin" ]; then
  export PATH=/usr/local/opt/ruby/bin:$PATH
  export LDFLAGS="-L/usr/local/opt/ruby/lib"
  export CPPFLAGS="-I/usr/local/opt/ruby/include"
  export PATH=`gem environment gemdir`/bin:$PATH
fi
# m1 silicon 芯片
if [ -d "/opt/homebrew/opt/ruby/bin" ]; then
  export PATH=/opt/homebrew/opt/ruby/bin:$PATH
  export LDFLAGS="-L/opt/homebrew/opt/ruby/lib"
  export CPPFLAGS="-I/opt/homebrew/opt/ruby/include"
  export PATH=`gem environment gemdir`/bin:$PATH
fi

make 时需要用到 ruby，所以需要配置环境变量 LDFLAGS 库文件 CPPFLAGS 头文件没有这个需求可以关掉

检查 ruby 版本

> ruby -v
ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-darwin22]

4. 安装 cocoapods

sudo gem install cocoapods
