java - 加载rJava库时为"unable to load shared object"

Question

我必须在 R 上加载 Excel 文件 .xlsx，但是:

library(xlsx)

Error: package or namespace load failed for ‘rJava’:.onLoad failed in loadNamespace() for 'rJava', details:call: inDL(x, as.logical(local), as.logical(now), ...)error: unable to load shared object 'C:/Users/danil/Documents/R/win-library/3.4/rJava/libs/x64/rJava.dll':LoadLibrary failure: Impossibile trovare il modulo specificato.Error: package ‘rJava’ could not be loaded

因此，我尝试安装 Java、Java SE-Development Kit 10 和 Java Runtime Environment 10(64 位)。但是，同样在这种情况下:

library(rJava)

Error: package or namespace load failed for ‘rJava’:.onLoad failed in loadNamespace() for 'rJava', details:call: inDL(x, as.logical(local), as.logical(now), ...)error: unable to load shared object 'C:/Users/danil/Documents/R/win-library/3.4/rJava/libs/x64/rJava.dll':LoadLibrary failure: Impossibile trovare il modulo specificato.

我能做什么？

Answer 1

这也发生在我身上(也是 Windows 10)，我的问题是环境变量设置不正确。就我而言，我必须这样做

Sys.setenv('JAVA_HOME' = 'C:/Program Files (x86)/Java/jre1.8.0_161/')

只需将文件夹名称更改为计算机中 Java 所在的位置，如果不起作用请告诉我。
