在R中安装RWeka包时出错

Question

我一直在尝试在我的RStudio (版本0.99.902)中安装RWeka包，但它一直给出下面的错误。我的操作系统是Mac OS Sierra版本10.12。

任何见解或线索都将非常感谢。

> install.packages("RWeka", lib="/Library/Frameworks/R.framework/Versions/3.3/Resources/library")

  There is a binary version available but the source version is later:
      binary source needs_compilation
RWeka 0.4-26 0.4-31             FALSE

installing the source package ‘RWeka’

我使用here指令重新配置rJava，然后从源代码重新编译(即使rJava已经安装无误)。这样做之后，RWeka安装就可以正常工作了。我在MacOS 10.10.5上。

sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
sudo R CMD javareconf

然后在R中：

install.packages("rJava", type = "source")
install.packages("RWeka", type = "source")
