我在CentOS 6.6 Linux上使用RubyOnRails 4.2.0构建了网站。 我不能资产预编译CoffeeScript。 宝石“therubyracer”运行时似乎发生了错误。 仅当CoffeeScript不存在时，预编译才会成功。
我使用gem“therubyracer”ver.0.11.0beta8和gem“libv8”ver.3.11.8.3。 怎么解决？ 感谢。

libv8 maintainer here.
The versions of libv8 and therubyracer you're using are ancient, please consider updating to the newest released versions. If you continue receiving errors, please consider opening up an issue in therubyracer's/libv8's issue trackers in github.
As a side note, you should consider asking the maintainers of a project directly first, through their issue tracker for example, before shooting a question in SO. Your question probably would have remained unanswered had I not been by chance looking for recent questions about libv8 here.
