在Windows上设置Java R接口(JRI)
在Windows上设置Java R接口(JRI)
提问于 2015-03-10 21:26:50
我已经跟踪了网络上的指南，并查看了关于堆栈溢出的问题，但我仍然无法在Windows上设置JRI。
以下是我所采取的步骤：
1)安装R
2)在R中执行install.packages("rJava")以安装rJava
3)创建具有值R_HOME的C:\Program Files\R\R-3.1.2系统变量。
4)在我的PATH变量中添加以下内容：C:\Program Files\R\R-3.1.2\bin\x64;C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri\x64
5)将JRI.jar (位于C:\Users\USERNAME\Documents\R\win-library\3.1\rJava\jri中)添加为IntelliJ中的依赖项
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
7)启动R并执行library("rJava")
8)运行我的程序来测试是否所有东西都设置好了
获取以下错误：

#如果删除VM选项以避免指定java.library.path，则会得到以下错误：

Please make sure that the JRI native library is in a directory listed in java.library.path.

最近(2018年)对我来说是这样做的:-
export R_HOME=$(R RHOME)然后编译如下：-
String[] enginargs = {"--no-save"};
REngine engine = org.rosuda.REngine.JRI.JRIEngine.createEngine(enginargs, null, false);
try {
engine.parseAndEval("print(\"Hello from R\");");
}
catch(Exception e ) {
System.err.println("OOps:-" + e.getMessage());
}
finally {
engine.close();
}然后在运行java时，要么将LD_LIBRARY_PATH设置为enclude，要么设置-Djava.library.path例如
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/R/site-library/rJava/jri/或
java -Djava.library.path=/usr/local/lib/R/site-library/rJava/jri/ MyMainClass页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
