为了尝试开始使用jruby上的rails项目，我从昨天开始就尝试使用rvm到rvm install jruby，并且对于通常出现以下形式的错误感到很沮丧：
Psych::SyntaxError: (<unknown>): found character '\t(TAB)' that cannot start any token. (Do not use \t(TAB) for indentation)
Here是完整日志的受害者，以防在那里找到任何有用的信息。
Here是rvm install ruby的更新版本（没有--1.9参数）。
~./gemrc的内容：
install: --no-rdoc --no-ri
update: --no-rdoc --no-ri
/etc/gemrc是空白的。
以下是安装日志rubygems.install.log：

~./gemrc包含：
install: --no-rdoc --no-ri
update: --no-rdoc --no-ri
删除标签并用空格替换它们可以解决问题。
