所以我尝试安装ruby 2.3.3并获悉：
Warning: port definitions are more than two weeks old, consider updating them by running 'port selfupdate'.
...
ruby-2.3.3/port_install.log Requirements installation failed with status: 56.
所以，我做了brew doctor并告诉我：
Warning: You have MacPorts or Fink installed:
/opt/local/bin/port
This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports
所以我跑：
sudo mv /opt/local ~/macports
然后我正在尝试安装ruby 2.3.3并且我有这个错误：
rvm install 2.3.3

在我没有这个问题之前，我已经安装了这个库，我需要做什么？
...更新
我跑：
rvm --debug requirements ruby
然后：
rvm install ruby-2.3.3

Please be aware that you just installed a ruby that requires 2 patches just to be compiled on an up to date linux system.
This may have known and unaccounted for security vulnerabilities.
Please consider upgrading to ruby-2.4.1 which will have all of the latest security patches.
Ruby was built without documentation, to build it run: rvm docs generate-ri
并且已安装。这是我第二次需要跑步：
rvm --debug requirements ruby
但是我遇到了另一个问题，例如：
brew update
remote: Repository not found.
fatal: repository 'https://github.com/amber-crystal/homebrew-amber/' not found
Error: Fetching /usr/local/Homebrew/Library/Taps/amber-crystal/homebrew-amber failed!
任何人都可以帮助我，我需要做什么？卸载并安装所有内容？
