无法从这些信息中找到答案。尝试查看 config.log 。
如果您是第一次安装，请尝试使用rbenv。按照步骤安装Ruby 2.0：

1. git clone git://github.com/sstephenson/rbenv.git .rbenv
2. echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
3. echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
4. git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
5. source ~/.bash_profile
6. rbenv install 2.0.0-p247
7. rbenv global 2.0.0-p247
8. rbenv rehash
9. ruby -v #This is to check whether Ruby got installed or not
10. gem install bundler
