重新安装rvm / rails

我最近不得不卸载rvm，然后重新安装rvm并重新安装rails -

看来rails没有正确安装，因为我无法启动rails。我正在使用ruby 2.3.0，并运行sudo gem install rails以获取最新版本的rails。

安装并运行bundle install和bundle update后，我收到此错误

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/tmpdir.rb:85:in `mkdir': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)

我尝试使用this问题的解决方案，但是找不到'apt-get命令'---但如果这需要类似的解决方案我会道歉！

我正在使用Mac OSX

编辑****

用gem update --- system更新gems后，我有一条新的错误信息：
