希望能对您的gem install therubyracer
工作有所帮助。这是错误:
$ gem install therubyracer
Building native extensions. This could take a while...
ERROR: Error installing therubyracer:
ERROR: Failed to build gem native extension.

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.
Provided configuration options:
--with-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include

extconf.rb:15:in `<main>': undefined method `include_path' for Libv8:Module (NoMethodError)
这是我在错误发生之前执行的一些重要步骤。他们工作得很好:
$ gem install libv8
$ brew install v8
我的环境是:
- Mac OS X Lion 10.7.4
- 红宝石1.9.3p194(2012-04-20修订版35410)[x86_64-darwin11.4.0](通过rvm)
- V8版本3.9.24(通过自制软件)
