1、更换cocoapods版本

sudo gem uninstall cocoapods -n /usr/local/bin cocoapods
sudo gem uninstall cocoapods-core
sudo gem uninstall cocoapods-deintegrate
sudo gem uninstall cocoapods-downloader
sudo gem uninstall cocoapods-plugins
sudo gem uninstall cocoapods-search
sudo gem uninstall cocoapods-stats
sudo gem uninstall cocoapods-trunk
sudo gem uninstall cocoapods-try

rm -rf ~/.cocoapods

sudo gem install cocoapods -v 1.7.5 -n /usr/local/bin 或
sudo gem install cocoapods

如果出现：

说明没有权限，需要输入
sudo gem install -n /usr/local/bin cocoapods

安装成功如下：

继续执行：
pod setup
漫长等待中................................

其他相关指令：

1、检查与升级Ruby环境：
ruby -v
sudo gem update --system

2、换掉Ruby镜像：
gem sources --remove https://rubygems.org/
gem source -a https://gems.ruby-china.org/
gem sources -l

如果出现以下结果说明正确
*** CURRENT SOURCES ***
https://gems.ruby-china.org/

3.CocoaPods 镜像
cd ~/.cocoapods/repos
pod repo remove master
git clone https://github.com/CocoaPods/Specs.git master
或：git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git master

4、接下来：
sudo gem install -n /usr/local/bin cocoapods

pod相关更新指令：
# 下载依赖的第三方库
pod install / pod install --no-repo-update

更新，可以加入第三方库名，只更新指定的库
pod update --verbose --no-repo-update(本地可用)
pod update

查找
pod search XXX

----------------------------------------------------------------------------------------------------------------------------
git:
git checkout XXX1(shanqizhi)
git merge --no-ff XXX2(master)
git push
git pull

新电脑之安装cocoapods：

ruby -v（新电脑一般都2.几版本，不用更新），有需要的可以执行权限更新：sudo gem update--system <输入开机密码>

成功

更换Ruby镜像
gem sources -l（更换成：https://gems.ruby-china.com）
gem sources--remove XXX
gem sources-a XXX

安装Cocoapods
sudo gem install -n /usr/local/bin cocoapods(安装CocoaPods)

然后不要直接执行pod setup，很慢
在生成了repos文件夹的情况下
国内清华镜像：
git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git ~/.cocoapods/repos/trunk

国外github上那个：
git clone https://github.com/CocoaPods/Specs.git ~/.cocoapods/repos/master

新增环境：
Homebrew：/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
利用Brew安装Protobuf环境：brew install swift-protobuf
brew -v

终端指令 --> 文件夹下的protobuf文件转swift：
find . -type f -iname '*.proto' -exec protoc --swift_out=. {} \;
