解决办法：
gem 2.7.7 can not run cocoapods 1.3.x . 1.4.x
you should install rubygem in 2.7.6
please:
gem install rubygems-update -v 2.7.6
and
update_rubygems
then
pod install or pod update
如果你的电脑收到管制，没有写入 /usr/bin 路径的权限
执行sudo gem update --system 2.3.0 -n /usr/local/bin
2.7.6版本的安装可能会报：
ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted @ rb_sysopen - /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/gem
而安装2.3.0版本没有问题
