问题描述
我已经安装了最新版本的 R (2.15.2) 和 Java (7.11)，并通过 RStudio (0.97.310) 尝试加载 rJava 包.它似乎安装正确，但是当我调用 library(rJava) 时，出现以下错误:
I have installed the latest versions of R (2.15.2) and Java (7.11), and through RStudio (0.97.310) I am trying to load the rJava package. It seemed to install properly, but when I call library(rJava) I get the following error:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: stop("No CurrentVersion entry in '", key, "'!
Try re-installing Java and make sure R and Java have matching architectures.")
error: object 'key' not found
Error: package/namespace load failed for ‘rJava’
rJava 的文档参考了 Java 1.5+，所以我想知道我是否需要安装一个古老版本的 Java 来解决这个问题.任何帮助将不胜感激！
The documentation for rJava makes reference to Java 1.5+, so I am wondering if I need to install an ancient version of Java to resolve this problem. Any help would be much appreciated!
推荐答案
好的，我想通了.我猜我应该阅读 rJava 开发网站上的发行说明.我已经安装了 Java，但没有安装 JDK.安装后，一切正常.
Ok, I figured it out. Guess I should have read the release notes on the rJava development website. I had installed Java, but not the JDK. Once I installed that, everything worked fine.
