我正在尝试使用rvm安装Ruby，但始终出现错误。

$ rvm install ruby

我希望ruby能够完美安装。相反，我收到以下错误消息：

Warning,new version of rvm available '1.29.9',you are using older version '1.29.9-next'.
You can disable this warning with:   echo rvm_autoupdate_flag=0 >> ~/.rvmrc
You can enable auto-update with:     echo rvm_autoupdate_flag=2 >> ~/.rvmrc
You can update manually with:        rvm get VERSION                         (e.g. 'rvm get stable')

当我检查有问题的configure.log文件时，看到以下内容：
