# ＭySmartPal - 編譯環境安裝
* 因使用cocoapod第三方套件需以下安裝步驟

## 查看當前ruby版本

> ruby -v
## 安装RVM
> curl -L get.rvm.io | bash -s stable
> source ~/.bashrc
> souce ~/.bash_profile

## 目前可裝版本
> rvm list known

## 按裝Homebrew

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

## Homebrew环境变量设置

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/Alex/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"

## 安装rvm

> rvm install 2.7.2
--
or
rvm reinstall ruby-2.7.2

## 再查看一次版本
> ruby -v

ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [arm64-darwin20]

(2擇1: 2為優)

## 安装Cocoapods - 1
M1安装前：

> 打開Finder->打開終端應用程序->打開工具程式，找到終端機.app，取得資訊，使用Rosetta打開勾上，然後重啟

M1另外需要安装：

> sudo gem install ffi

1查看源$
> gem sources -l

2删除源$
> sudo gem sources --remove https://rubygems.org/

3设置新的源$

> sudo gem sources -a https://gems.ruby-china.com/

## 安装CocoaPods - 2

先卸载cocoapods乾淨：
> sudo gem uninstall cocoapods

查看cocoapods版本：

> pod --version

不指定版本安装(M1使用這個)：

> sudo gem install -n /usr/local/bin cocoapods

> pod setup

然後進入開發程式專案檔工作目錄
更新第三方套件libray內容
>pod install

解決方案：解除安裝重灌 brew
[下載](https://raw.githubusercontent.com/Homebrew/install/master/uninstall)... 並儲存為 uninstall.rb，再執行 ruby uninstall.rb

#!/usr/bin/ruby

STDERR.print <<EOS

Kernel.exec "/bin/bash", "-c", '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"' + ' uninstall ' +  ARGV.join(" ")
