Question

我正在尝试将一些宝石安装到Logstash 1.4.2

中

为此我用Google搜索并找到了答案（how to add gems into logstash）

在得到答案后，我可以轻松安装续集宝石。

但是当我尝试像这样安装mysql gem时：

cd logstash-1.4.2/
env GEM_HOME=vendor/bundle/jruby/1.9 GEM_PATH="" java -jar vendor/jar/jruby-complete-1.7.11.jar -S gem install mysql

我收到以下错误：

Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
    ERROR: Failed to build gem native extension.

    java -jar /home/deepak/logstash-1.4.2/vendor/jar/jruby-complete-1.7.11.jar extconf.rb
NotImplementedError: C extension support is not enabled. Pass -Xcext.enabled=true to JRuby or set JRUBY_OPTS.

Gem files will remain installed in /home/deepak/logstash-1.4.2/vendor/bundle/jruby/1.9/gems/mysql-2.9.1 for inspection.

我对ruby很新，所以我不知道这里缺少什么，我试图添加-Xcext.enabled = true

 env GEM_HOME=vendor/bundle/jruby/1.9 GEM_PATH="" java -jar vendor/jar/jruby-complete-1.7.11.jar -S -Xcext.enabled=true gem install mysql

但是，这给了我另一个错误：

NameError: uninitialized constant Xcext
  const_missing at org/jruby/RubyModule.java:2690
         (root) at -Xcext.enabled=true:1

另外，我正在运行Ubuntu 14.04 64位。如果需要更多信息，请发表评论。
