Mac 安装rJava出错，R library(rJava)出错

问题描述

下载Java for Mac安装后，然后install.packages("rJava"),R library(rJava)出错，错误描述如下：

错误: package or namespace load failed for ‘rJava’:
loadNamespace()里算'rJava'时.onLoad失败了，详细内容：
调用: dyn.load(file, DLLpath = DLLpath, ...)
错误: 无法载入共享目标对象‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so’：:
dlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: @rpath/libjvm.dylib
Referenced from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
Reason: image not found

解决方案

链接libjvm.dylib到用户库

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

链接libjvm.dylib到R库

sudo ln -s /usr/local/lib/libjvm.dylib /Library/Frameworks/R.framework/Versions/3.4/Resources/lib/
