无法加载rjava

Question

执行库（xlsx）时发生以下错误。

Error: package or namespace load failed for ‘xlsx’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object'/Library/Frameworks/R.framework/Versions/3.5/Resources/library/rJava/libs/rJava.so':
 dlopen(/Library/Frameworks/R.framework/Versions/3.5/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: 
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/server/libjvm.dylib
Referenced from:/Library/Frameworks/R.framework/Versions/3.5/Resources/library/rJava/libs/rJava.so
Reason: image not found

“ rJava”的加载路径是“ jdk-9.jdk”。但是，我的JAVA_HOME路径如下。

Java interpreter : /usr/bin/java
Java version     : 1.8.0_172
Java home path   : /Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/jre
Java compiler    : /usr/bin/javac
Java headers gen.: /usr/bin/javah
Java archive tool: /usr/bin/jar

trying to compile and link a JNI program
detected JNI cpp flags    : -I$(JAVA_HOME)/../include -I$(JAVA_HOME)/../include/darwin
detected JNI linker flags : -L$(JAVA_HOME)/lib/server -ljvm
clang -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/jre/../include -I/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/jre/../include/darwin  -I/usr/local/include   -fPIC  -Wall -g -O2  -c conftest.c -o conftest.o

JAVA_HOME        : /Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/jre
Java library path: $(JAVA_HOME)/lib/server
JNI cpp flags    : -I$(JAVA_HOME)/../include -I$(JAVA_HOME)/../include/darwin
JNI linker flags : -L$(JAVA_HOME)/lib/server -ljvm

我尝试了以下解决方案，但问题仍然存在。

dyn.load ('/ Library / Java / JavaVirtualMachines / jdk1.8.0_172.jdk / Contents / Home / jre / lib / server / libjvm.dylib')    
sudo ln -s $/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/jre/lib/server/libjvm.dylib /usr/local/lib

我不知道如何正确修复jdk的路径。 如果有人能为我提供解决问题的线索，我将不胜感激。

谢谢。
