在Mac OS X Lion上``gem install therubyracer`失败 [英] `gem install therubyracer` fails on Mac OS X Lion

问题描述

我希望在获得 gem install therubyracer 的帮助。这是错误：

  $ gem install therubyracer 
构建本机扩展。这可能需要一段时间... 
错误：安装therubyracer时出错：
错误：无法构建gem原生扩展。 
 
 /Users/david/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb 
在-lobjc中检查main（）...是
 *** extconf.rb失败*** 
由于某些原因无法创建Makefile，可能缺少
必需的库和/或头文件。查看mkmf.log文件以获取更多
的详细信息。您可能需要配置选项。 
 
提供的配置选项：
 --with-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 = / Users / david / .rvm / rubies / ruby​​-1.9.3 -p194 / bin / ruby​​ 
 --with-objclib 
  - -without-objclib 
 extconf.rb：15：在< main>中：未定义的方法include_path用于Libv8：Module（NoMethodError）
  

以下是我在出错前执行的一些显着步骤。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


• ruby​​ 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）

解决方案

I would appreciate some help in getting gem install therubyracer to work. Here is the error:

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

        /Users/david/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb
checking for main() in -lobjc... yes
*** 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
    --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=/Users/david/.rvm/rubies/ruby-1.9.3-p194/bin/ruby
    --with-objclib
    --without-objclib
extconf.rb:15:in `<main>': undefined method `include_path' for Libv8:Module (NoMethodError)

Here are some notable steps that I ran before the error. They worked fine:

$ gem install libv8
$ brew install v8

My environment is:

• Mac OS X Lion 10.7.4
• ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0] (via rvm)
• V8 version 3.9.24 (via homebrew)

解决方案

This worked for me:

$ gem uninstall libv8
$ gem install therubyracer
