无法在JRuby中安装therubyracer [英] Can't install therubyracer in JRuby

问题描述

我先安装了RVM，然后安装了Jruby，这是我键入时得到的版本:jruby -v:

I've installed RVM and then Jruby, this the version that i get when i type: jruby -v:

jruby 1.6.5.1(ruby-1.8.7-p330)(2011-12-27 1bf37c2)(Java HotSpot(TM)客户端VM 1.7.0_02)[linux-i386-java]

jruby 1.6.5.1 (ruby-1.8.7-p330) (2011-12-27 1bf37c2) (Java HotSpot(TM) Client VM 1.7.0_02) [linux-i386-java]

问题是我无法安装therubyracer gem，当我尝试通过jruby -S gem安装therubyracer时，我得到了这个提示:

The problem is that I can't install therubyracer gem, i get this when i try to install by jruby -S gem install therubyracer:

/usr/local/rvm/rubies/jruby-1.6.5.1/bin/jruby extconf.rb

Could not create Makefile due to some reason, probably lack of

Provided configuration options:
        --with-opt-dir
        --without-opt-dir

        --without-opt-include=${opt-dir}/include

        --srcdir=.
        --curdir
        --ruby=/usr/local/rvm/rubies/jruby-1.6.5.1/bin/jruby

我也尝试使用--1.9参数来强制使用另一个ruby版本，但是无论如何它还是失败了.甚至我尝试安装libv8，但上面也遇到相同的错误.

I also tried with --1.9 parameter, to force to use another ruby version, but it fails anyway. Even I tried to install libv8, but i get the same error above.

有什么想法吗? 我有CentOS 5.7

Any ideas? I have CentOS 5.7
