Mac 搭建多个Cocoapods版本共存

1 给系统自带的Ruby版本(System) 安装Cocoapods

2 Rvm 安装并管理多个版本Ruby

1、安装Rvm

curl -sSL https://get.rvm.io | bash -s stable

如果报错curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused 链接不到服务器

在 /etc/host 文件夹下添加

199.232.28.133 raw.githubusercontent.com

查看是否安装成功

~ ➤ rvm -v
rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

查看Ruby版本

~ ➤ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.8]
[ruby-]2.4[.10]
[ruby-]2.5[.8]
[ruby-]2.6[.6]
[ruby-]2.7[.2]
[ruby-]3[.0.0]

3 安装 指定版本ruby-2.7.2

rvm install 2.7.2

如果报错 Searching for binary rubies, this might take some time No binary rubies available for: osx/10.11/x86_64/ruby-2.2.4. Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies. Checking requirements for osx. Installing requirements for osx. Updating system....... Error running 'requirements_osx_brew_update_system ruby-2.2.4',

#执行
rvm autolibs read-only

继续安装Ruby

rvm install 2.7.2

4 安装Cocoapods

把Ruby切换到刚下载的版本

# 把Ruby切换到刚下载的版本
rvm use 2.7.2
# 按照之前的逻辑正常安装Cocoapods
sudo gem install -n /usr/local/bin cocoapods
pod setup

此时Mac上已经同时存在了两个Cocoapods版本
1 一个是系统自带Ruby版本下安装的Cocoapods
2 另一个是Rvm管理下的Ruby版本下的Cocoapods
如果想安装多个Cocoapods，只需重复3，4步骤就可以了,一个Ruby版本下可以安装一个Cocoapods环境
