温馨提示： 如果在安装中 切换网络 依然出现curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused 可参考这篇文章
主要步骤: 前往文件夹 输入 /etc 找到hosts 文件 ，拷贝出来，在里面添加 文章中的几行代码， 保存之后 再替换etc中的hosts
准备环境
1、安装/升级RVM
1.1 确定是否存在RVM
输入 rvm -v, 查看命令执行是否成功。
如果输出-bash: rvm: command not found 表示RVM不存在，需要安装。
如果输出rvm 1.29.10 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io] 表示RVM存在，可以进行下一步。
1.2 安装RVM
如果RVM不存在，需要重新安装。
输入命令curl -L get.rvm.io | bash -s stable或者curl -L https://get.rvm.io | bash -s stable
会自动开始下载。
macdeiMac:~ mac$ curl -L https://get.rvm.io | bash -s stable

.....
* To start using RVM you need to run `source /Users/mac/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.
👉 Donate: https://opencollective.com/rvm/donate
出现提示之后，表示下载完成，按照提示，要执行source ~/.rvm/scripts/rvm来安装。
执行rvm -v 来确定是否安装成功。正确输出，表示安装成功。
1.3 升级RVM
当有新版本的RVM时，想升级了，输入和安装一样的命令：curl -L get.rvm.io | bash -s stable或者curl -L https://get.rvm.io | bash -s stable
Upgrade of RVM in /Users/jasonOs/.rvm/ is complete.
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.
查看版本rvm -v时，有提示
Please open a new shell or run one of the following commands:
rvm reload
echo rvm_auto_reload_flag=1 >> ~/.rvmrc # OR for auto reload with msg
echo rvm_auto_reload_flag=2 >> ~/.rvmrc # OR for silent auto reload
按照提示需要输入某一个命令 ，此时控制台输入rvm reload
1.4 gem 升级
sudo gem update --system
如果报“无权限”，使用
sudo gem update -n /usr/local/bin --system
2、安装 brew
1.1 确定是否存在brew
输入brew -v,
如果输出-bash: brew: command not found 则没有安装，需要安装。
如果输出brew ..... 表示brew存在，可以进行下一步。
1.2 安装brew
官方 --- - ⚠️ 不建议尝试
输入/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"。等待自动下载。
如果出现curl: (7) Failed to connect to raw.githubusercontent.com port 443: Connection refused表示网络环境有问题，可以切换不同的网络试试镜像方式 强烈推荐 NB的飞起
简单五步安装brew
3、升级ruby
参考来源
其实此步骤一般来说是不需要的，因为本来系统自带的应该都是2.3.3（要求最低是2.2）已经满足安装cocoapod的要求了。
查看当前版本ruby - v
如果想升级版本，采用一下方法：
输入命令： brew install ruby

==> Caveats
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"

安装升级后，再次查看版本，发现还是原来的版本，输入以下命令
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
2、安装CocoaPods
接下来就开始安装cocoapod了
这个步骤参考了这篇文章（但是这篇文章的最后 pod setup不成功）
步骤2、更换Ruby镜像
1、先看现在的镜像地址：
输入命令： gem sources -l
如果是
*** CURRENT SOURCES ***
https://rubygems.org/
需要替换成国内的。如果本身就是国内的镜像，则不需要步骤2的操作
2、替换成国内镜像
先移除现在的镜像
终端输入：
gem sources --remove https://rubygems.org/
然后替换成现在大中华地区可用的(taobao的那个镜像已经不好用了)
gem sources -a https://gems.ruby-china.com/
执行完之后查看是否替换成功
gem sources -l
输出结果
*** CURRENT SOURCES ***
https://gems.ruby-china.org/
说明替换成功
3、镜像替换之后开始进行cocoapods安装
终端输入：
sudo gem install -n /usr/local/bin cocoapods 或者sudo gem install cocoapods -n /usr/local/bin
如果出现权限问题
可更换命令：sudo gem install cocoapods --user-install
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0 directory.
开始下载之后 会出现以下输出

之后在执行
pod setup
输出

这是一个漫长的等待。。。
你没有看错，我的速度就是2、2、2 ...不过此时我的内心是平静的【大写的滑稽脸】
你可以command+n新建一个终端窗口，执行cd ~/.cocoapods/进入到该文件夹下，然后执行du -sh *来查看大小，每隔几分钟查看一次,他会告诉你，确实是有文件在往里面写【无聊脸】
等待了2个小时之后 见红了 。。。

我平静的内心依然毫无波澜。。。
在一个文章上找到了解决方案
1、卸载cocoapod（感觉这一步可以省略）
终端输入：
sudo gem uninstall cocoapods
这个时候需要输入电脑密码（请注意，输入密码不是显示，光标也不会动）输入密码之后
此时终端输出：
Remove executables:
pod, sandbox-pod
in addition to the gem? [Yn]
需要你输入 ‘Y’ 按enter键
终端继续输出：
Removing pod
Removing sandbox-pod
Successfully uninstalled cocoapods-1.4.0
2、重装cocoapods
终端输入：
sudo gem install -n /usr/local/bin cocoapods
终端输出：

Successfully installed cocoapods-1.4.0

1 gem installed
终端输入
sudo chmod +rx /usr/local/bin
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
pod setup
此时终端输出：
Setting up CocoaPods master repo
$ /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --progress

此时的速度比刚才比，内心已经震精了。。。
上面的进度跑完之后会继续跑下面这行
Resolving deltas: 37% (423306/1144069)
跑完还会跑
Checking out files: 10% (22244/227244)
100%后就看到了期待已久的输出：
CocoaPods 1.5.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.5.0.beta.1
Setup completed
completed..............................................
此时我的内心汹涌澎湃。。。。。
最后全部安装完整之后 查看了文件大小 1.5G，不敢想象如果用2k的速度，得用多久， 之前也试过，进行pod setup跑了1天 大概到80%几，见红了。。。
Cloning spec repo cocoapods 卡住
cocoaPod安装完之后， 第一次进行pod install操作。可能会出现卡住不动或者的情况，只是由于cocoapPod安装好了， 但是必要的资源还没准备好，后台在默默的下载，具体大小，可根据git的api中的size查看
Cloning spec repo `cocoapods` from `https://github.com/CocoaPods/Specs.git`
[!] Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `cocoapods`.
You can try adding it manually in `/Users/98-elden/.cocoapods/repos` or via `pod repo add`.
解决办法：
1、去git仓库下载好资源，倒入本地文件夹下.cocoapods/repos/cocoapods/
解决方法来源
安装cocoapod之后，提示 gem executables will not run
https://www.jianshu.com/p/6f4f253bc254
2、换源
步骤1、更换国内的镜像, 清华的不错
解决方法来源
$ cd ~/.cocoapods/repos
$ pod repo remove master
$ git clone https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git master
步骤2、项目中的podfile文件修改源地址：
source 'https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git'
更新时遇到警告
WARNING: You don't have /Users/xxx/.local/share/gem/ruby/2.6.0/bin in your PATH,
gem executables will not run.
解决方案：来源于stackoverflow
# 1、打开配置文件
open ~/.zshrc
# 2、在最后加以下2行：
export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"
export PATH="$PATH:$GEM_HOME/bin"
# 3、重置资源
source ~/.zshrc
放弃了系统的ruby，用第三方代替
由于各种权限问题， 放弃了系统的ruby。安装了rbenv 参考这里安装

使用 git 的时候发现一直提示 HTTP/2 stream 1 was not closed cleanly before end of the underlying stream。 通过排查发现，是 git 默认使用的通信协议出现了问题，可以通过将默认通信协议修改为 http/1.1 来解决该问题。
