使用cocopod遇到问题

1.需要安装ruby最新版时安装不上

使用cocopod时，需To install do: 'rvm install "ruby-2.6.0"'；运行rvm install "ruby-2.6.0时，遇到：

Error running './configure --prefix=/Users/mc/.rvm/rubies/ruby-2.6.0  --with-opt-dir=/usr/local/opt/libyaml:/usr/local/opt/readline:/usr/local/opt/libksba:/usr/local/opt/openssl@1.1 --disable-install-doc --enable-shared',

please read /Users/mc/.rvm/log/1571023136_ruby-2.6.0/configure.log

There has been an error while running configure. Halting the installation.

解决办法：

1.先运行：xcode-select --install

2.再运行：rvm install "ruby-2.6.0“

2.运行pod install，出现以下问题：
