安装 rJava package 的问题

[英]Problems with installing rJava package

原文 2021-02-24 15:56:14 5 1 java/ r/ xlsx

I have tried to call the library xlsx, since I want to save data in multiple-sheets excel files, but I got a Java-related error.我试图调用库 xlsx，因为我想将数据保存在多张 excel 文件中，但出现与 Java 相关的错误。 Even when I run library(rJava) I have this error code:即使我运行 library(rJava) 我也有这个错误代码：

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/me/Documents/R/win-library/4.0/rJava/libs/x64/rJava.dll': LoadLibrary failure: The specified module could not be found.错误：package 或“rJava”的命名空间加载失败：“rJava”的 loadNamespace() 中的 .onLoad 失败，详细信息：调用：inDL(x, as.logical(local), as.logical(now), ...)错误：无法加载共享 object 'C:/Users/me/Documents/R/win-library/4.0/rJava/libs/x64/rJava.dll'：LoadLibrary 失败：找不到指定的模块。

The solutions I have found online are quite old and none helped to solve the issue: I have tried to reinstall Java 64 bit on my OS (Windows 10-64bit), and the package rJava, I have tried to set Java home with Sys.setenv(JAVA_HOME="C:\Program Files\Java\jre1.8.0_271\") without success.
