用Mac系统的R载入rJava包的时候失败，原因是image not found，这要怎么办？

技术小白一个，希望大神能够帮帮忙。我已经按照网上的教程安装rjava和Rwordseg。rjava install成功了但加载不出来错误如下：

library(rJava)
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
这要怎么办呢？
