我安装了一个红宝石版本如下
$ rvm install ruby-1.9.3-p448-dev
当我检查版本如下
$ ruby -v
ruby 1.9.3p448 (2013-06-27 revision 41675) [i686-linux]
但是当我尝试像下面这样安装 travis
$ gem install travis
Building native extensions. This could take a while...

那么如何避免上述native extensions
错误并travis
成功安装使用gem
编辑
sudo
当我通过以下方式尝试命令时
sudo gem install travis
我收到以下消息作为成功
Building native extensions. This could take a while...
Successfully installed travis-1.5.2
1 gem installed
Installing ri documentation for travis-1.5.2...
Installing RDoc documentation for travis-1.5.2...
现在我要做的就是设置environ
变量travis
,因此我尝试了以下命令
$ travis encrypt -r travis_uname/app_name EMAIL_HOST_KEY=key_value
并得到以下奇怪的错误

那么最后如何避免上述错误并使上述 travis 命令成功运行?
