我在宝石文件中添加了宝石“sunspot_rails”,并运行捆绑安装.我在安装libv8时收到错误,错误信息如下：
Installing libv8 (3.3.10.4) with native extensions Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /opt/local/bin/ruby extconf.rb *** extconf.rb Failed *** Could not create Makefile due to some reason,probably lack of necessary libraries and/or headers.

Make sure that `gem install libv8 -v '3.3.10.4'` succeeds before bundling.
当我运行gem安装libv8 -v’3.3.10.4’时,会打印以下错误消息：

如何正确安装libv8？
解决方法
强制extconf.rb文件在安装时需要rubygems：
RUBYOPT=-rrubygems gem install libv8 -v '3.3.10.4'
