在Mac OSX上运行的R Studio中安装rJava和xlsx

Question

我正在尝试在R Studio中安装“ xlsx”库。但是由于我没有安装“ rJava”，所以安装没有成功。

否，当我在Mac中安装jdk之后尝试安装“ rJava”时，在安装过程中仍然出现相同的错误，以下是两个库的错误。

"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':

要使rJava受到认可似乎有些棘手。似乎R可能试图在错误的位置寻找它，在这种情况下，您可以尝试解决类似问题或对Error of java path on loading rJava package的评论

tidyverse系列软件包会根据您需要xlsx库的内容提供用于读取和写入不依赖Java的xlsx文件的软件包，请参见Issue while connecting rJava in R Studio
