无法在JRuby中安装therubyracer

我已经安装了RVM,然后安装了Jruby,这是我input的版本:jruby -v:

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,我不能安装therubyracergem,我得到这个,当我尝试安装由jruby -Sgem安装therubyracer:

/usr/local/rvm/rubies/jruby-1.6.5.1/bin/jruby extconf.rb WARNING: JRuby does not support native extensions or the `mkmf' library very we$ Check http://kenai.com/projects/jruby/pages/Home for alternatives. Checking for Python...Unable to build libv8: Python not found! *** 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. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/usr/local/rvm/rubies/jruby-1.6.5.1/bin/jruby 

我也试着用–1.9参数,强制使用另一个ruby版本,但是无论如何它失败了。 即使我试图安装libv8,但我得到上面的相同的错误。

有任何想法吗? 我有CentOS 5.7

你想要Ruby Rhino 。

只是为了澄清,在你的Gemfile中是这样的:

 gem 'therubyrhino' 

接下来在命令行中用:

 jruby -S bundle install 

我有同样的问题,但在Gemfile中定义therubyrhino并没有解决我的问题,bundler不断尝试安装libv8。

发生这种情况是因为我在Gemfile中定义了twitter-bootstrap-rails gem,并且依赖于较少的gem(依赖于therubyracer),所以我改变了较少的gem以使用不依赖于较少的静态分支(如问题https://github.com/seyhunak/twitter-bootstrap-rails/issues/22 ):

 gem 'twitter-bootstrap-rails', :git => "git://github.com/seyhunak/twitter-bootstrap-rails.git", :branch => "static"
