编辑：
gem env输出：

我在听完各种文章之后想出来了。
遵循步骤。
$rvm get head
$rvm --force 2.0.0
$gem update
$gem install rails
经历了顺利。

抱歉无法编辑终端输出。 线太多了！
这是一个帮助我的答案： Ruby on Rails – 无法将“\ x89”从ASCII-8BIT转换为UTF-8用于xxx / xxxx / xxxx
您需要更新/安装支持转换的rdoc gem版本。 然后，在安装rails或重新生成文档时，在生成文档期间不会出现这些错误。
gem install rdoc
然后重新生成文档
gem rdoc --all --overwrite
然后做gem update和gem install rails
另外，请确保rvm是函数type rvm | head -1 type rvm | head -1
得到它看看你的错误： –
`Gem文件将保留在/Users/SMD/.rvm/gems/ruby-2.0.0-p247/gems/atomic-1.1.13中
检查. so it is for gem name as . so it is for gem name asprimefacesand you required java jdk 8 github.com/headius/ruby-atomic last line stated as of 1.1.0 , JDK8是构建primefacesgem所必需的，因为它试图使用新的primefaces
请安装JDK 8

这是rdoc gem问题我会在github上找到这个问题 。 更新rdoc gem并重新安装rails。
$ gem install rdoc $ gem install rails
安装convmv 1.12-2（Ubuntu 12.04.3），解决
