尝试使用"gem install therubyracer -v'0.10.2'"在小牛上安装therubyracer但是我收到以下错误:

Installing libv8 (3.3.10.3) with native extensions /usr/local/rvm/rubies/ruby-1.9.3-head/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:552:in `rescue in block in build_extensions': ERROR: Failed
to build gem native extension. (Gem::Installer::ExtensionBuildError)
/usr/local/rvm/rubies/ruby-1.9.3-head/bin/ruby extconf.rb
Checking for Python...*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
我在therubyracer github网站上找到了问题报告,它建议卸载并重新安装libv8,但这不适用于我的Ubuntu 11.04机器.任何想法 - 还是我坚持旧版本一段时间？
