安装好的“xlsx”不能正常加载

library("xlsx")

报错：

载入需要的程辑包：rJava
Error: 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
错误: 无法载入程辑包‘rJava’

 

解决方法：

 

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

After that, in RStudio, loading rJava works through loading of the "xlsx" package.
