看到这么一“堆” 真的是无从下手，没遇到过这么长的，有经验的可能会从中找到问题所在，我是根据最初的出现--gem -- ruby等字眼，判断 可能是ruby/gem的问题
起初认为是ruby版本过低了，于是升级ruby。升级过程中发现RVM不存在，于是安装RVM
（通过 rvm list known 命令查看已知的 Ruby 版本，提示-bash: $: command not found，说明你的RVM不存在，重新安装下-----
$ \curl -sSL https://get.rvm.io | bash -s stable
$ source ~/.bashrc
$ source ~/.bash_profile
一步步执行
修改 RVM 的 Ruby 安装源到 Ruby China 的 Ruby 镜像服务器，这样能提高安装速度）
$ echo "ruby_url=https://cache.ruby-china.org/pub/ruby" > ~/.rvm/user/db
之后执行：rvm list known 查看ruby的版本
# 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[.7]
[ruby-]2.3[.4]
[ruby-]2.4[.1]
ruby-head
这些是ruby的版本 最新2.4
安装最新ruby ------- rvm install 2.4
No checksum for downloaded archive, recording checksum in user configuration.
ruby-2.4.1 - #extracting rubygems-2.6.14....
ruby-2.4.1 - #removing old rubygems.........

Install of ruby-2.4.1 - #complete
Ruby was built without documentation, to build it run: rvm docs generate-ri
安装成功
之后试了下 pod install 还是报错 但是 现在 出来明确问题出在哪了 --- /Users/qqqq/.rvm/rubies/ruby-2.0.0-p643/lib/ruby/site_ruby/2.0.0/rubygems.rb:270:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException) 提示我没有找到gem 所以重新安装下gem ----
sudo gem uninstall cocoapods
gem install cocoapods
两步执行 最后提示 28 gems installed 安装成功
执行 pod install 成功
（最后 如果 还出现 上述问题 ruby之前没删除 ，存在好几个版本， 执行rvm --default use 2.4.1 语句 让ruby默认换成最新的版本）
