问题描述

我已经关注了网络上的指南并查看了有关stackoverflow的问题，但我仍无法在Windows上设置JRI。

I have followed guides on the web and looked at questions on stackoverflow but I am still not able to set up JRI on Windows.

以下是我的步骤采取：

1）安装R

2）执行 install.packages（ r中的rJava）安装rJava

2) Execute install.packages("rJava") in R to install rJava

3）创建 R_HOME 系统变量值 C：\Program Files \R\R-3.1.2

3) Create a R_HOME system variable with value C:\Program Files\R\R-3.1.2

4）添加跟随我的 PATH 变量： C：\Program Files \R\R-3.1.2 \ bin \ x64; C： \ Users\USERNAME \Documents\R\win-library\3.1\rJava \ jri \ x64

4) Add the following to my PATH variable: C:\Program Files\R\R-3.1.2\bin\x64;C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri\x64

5）添加了JRI.jar（位于 C：\ Users \USERNAME \Documents\R\win-library\3.1\rJava \ jri ）作为IntelliJ中的依赖项

5) Added the JRI.jar (located in C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri) as a dependency in IntelliJ

6）将IntelliJ中的VM选项设置为 -Djava.library.path = C：\ Users \USERNAME\Documents\\ R\win-library\3.1\rJava \ jri \ x64

6) Set the VM options in IntelliJ to -Djava.library.path=C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri\x64

7）启动R并执行 library（rJava）

8）运行我的程序来测试是否所有内容都已设置

8) Run my program to test if everything is set up

获取以下错误：

如果我删除VM选项以便java.library.path不是指定然后我收到以下错误：

If I remove the VM option so that java.library.path isn't specified then I get the following error:

Cannot find JRI native library!
Please make sure that the JRI native library is in a directory listed in java.library.path.

java.lang.UnsatisfiedLinkError: no jri in java.library.path
