我是Ruby和Gems的新手,所以我可能会遗漏一些显而易见的东西:

ERROR:  Error installing matlab-ruby:
    ERROR: Failed to build gem native extension.

        /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

我收到了几个Gems的错误,其中包括Ruby GSL。

我正在运行Mac OS 10.7.2,Ruby 1.8.7和XCode 4.2,如果这很重要的话。

完整控制台输出:

我终于安装了gsl!

重要的是安装与您正在使用的rb-gsl版本匹配的gsl版本,在我的情况下为1.14。

对于那些对我这样的c编译垃圾一无所知的人:

下载并解压缩您的gsl包 导航到终端中的该文件夹 输入以下命令:

./configure
make clean
make
sudo make install

make install命令我猜它会把它安装到标准位置吗?

一旦我这样做了,

sudo gem install gsl

工作得很好!

我还发现了这篇很棒的介绍文章,关于安装带有原生扩展的gem,以及所有这些东西实际上是做什么的:
