rJava 也已安装。任何帮助将不胜感激

建议的解决方案:

1。在命令行启动 R(测试解决方案)

> sudo R CMD javareconf
> export LD_LIBRARY_PATH=$JAVA_LD_LIBRARY_PATH
> LD_LIBRARY_PATH=$(/usr/libexec/java_home)/jre/lib/server: open -a RStudio

现在在 RStduio 中:

> install.packages("rJava", type = "source")
> install.packages("openNLP")
> require(rJava)
> require(openNLP)

从 finder 启动 RStudio...(El Capitan)

您必须将 libjvm.dylib 链接到 /usr/lib...

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

现在通过 finder 启动...
