问题描述
我使用的是 64 位机器,具有最新版本的 R (3.1.2)、最新的 RStudio 版本 (0.98.1091) 和最新的 JAVA(版本 8 更新 31).
I am using a 64-bit machine, with the latest version of R (3.1.2), the latest RStudio version (0.98.1091) and the latest JAVA (Version 8 Update 31).
我试图要求 rJava (rJava_0.9-6),结果是以下错误:
I tried to require rJava (rJava_0.9-6) and the result is the following error:
require(xlsx)
Carregando pacotes exigidos: rJava
Error : .onLoad falhou em loadNamespace() para 'rJava', detalhes:
chamada: fun(libname, pkgname)
erro: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.
Failed with error: ‘package ‘rJava’ could not be loaded’
我已经尝试重新安装 Java,但没有成功.
I already tried to re-install Java with no sucess.
有人知道我该如何解决这个问题吗?
Does anybody know how can I solve this problem?
推荐答案
我认为此时的问题是您的 Java 是 32 位的,而您的 R 是 64 位的.这就是为什么您会收到 R 和 Java 具有不同架构
错误的原因.
I think the problem on this occasion is that your Java is 32-bit, whereas your R is 64-bit. This is why you get a R and Java have different architectures
error.
为了检查您在 Windows 上的 Java 版本,请键入:
In order to check what your Java version is on Windows type:
java -d64 -version
在命令行中提到 此处.
我认为一旦你安装了正确的 Java 版本,即 64 位,那么加载你的 xlsx
库就可以了!
I think that once you install the correct Java version i.e. the 64-bit on this occasion then loading your xlsx
library will work!
