无法在 RStudio 中加载 rJava [英] Failing to load rJava in RStudio

问题描述

这样我就可以使用依赖于 rJava 的库.当我尝试加载 rJava 时，我得到了这个:

So that I can use libraries dependent on rJava. When I try loading rJava, I get this:

Error: package or namespace load failed for ‘rJava’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object 

'/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so':dlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6):库未加载:@rpath/libjvm.dylib引用自:/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so原因:找不到图片

然后我跑

sudo R CMD javareconf

使用此版本的 Java:

With this version of Java:

java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)

出现以下错误:

推荐答案

在 macOS 上，Java、R 和 RStudio 配置存在问题.我在这个问题上挣扎了一段时间.

On macOS there are issues with Java, R, and RStudio configuration. I have struggled with this one for some time.

您可以在此处找到一些信息:R、Java、rJava 和 macOS 冒险

You can find some info here: R, Java, rJava and macOS adventures

一般来说，您必须确保正确设置 Java，您需要启用 JNI 对 Java 的支持，您必须确保使用 Oracle 的 Java 而不是 Apple 的 Java(至少，对我来说，这是一种首选方式)在 macOS 上使用 Java).

In general, you have to make sure to properly set Java, you need to enable JNI support for Java, you have to make sure to use Oracle's java instead of Apple's one (at least, for me, it's a preferred way of working with Java at macOS).
