我尝试在R中安装名为topicmodels的软件包，但没有成功。以下是我尝试的方法...
操作：使用install.packages("topicmodels")安装程序包
结果：

package ‘topicmodels’ is available as a source package but not as a binary

Warning in install.packages :
  package ‘topicmodels’ is not available (for R version 3.1.0)

我说好吧，我们从源代码安装
操作：install.packages("/Users/my_name/Downloads/topicmodels_0.2-1.tar.gz",repos=NULL,type="source")
结果：

* installing *source* package ‘topicmodels’ ...
** package ‘topicmodels’ successfully unpacked and MD5 sums checked

所以后来我研究了这个GSL的东西，发现了this link。当时我以为我所有的问题都解决了，当我最终按照这些方向操作时。我得到了下面的错误（在终端中）...
