R / RStudio，Yosemite和Java [英] R/RStudio, Yosemite, and Java

问题描述

我昨天升级到OSX Yosemite。当我在 RStudio 中运行 library（xlsx）时，程序崩溃并收到消息：打开'RStudio 你需要安装旧的Java SE 6运行时。当我在中运行 library（xlsx）时，我得到相同的结果和关于打开 R 的消息R 。

I upgraded to OSX Yosemite yesterday. When I run library(xlsx) in RStudio, the program crashes and I get the message: "To open 'RStudio' you need to install the legacy Java SE 6 runtime." I get the same result and message about opening R when I run library(xlsx) in R.

以下是我的详细信息：

Mac Yosemite, Version 10.10.2
R version 3.1.2 (2014-10-31) 
Platform: x86_64-apple-darwin13.4.0 (64-bit)

我有Java版本8更新31.我运行 java -version 并且收到此消息：没有Java运行时，请求安装。所以我安装了 Java SE Development Kit 8u31 。现在：

I have Java Version 8 update 31. I ran java -version and got this message: "No Java runtime present, requesting install." So I installed Java SE Development Kit 8u31. Now:

java -version
java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)

这没有办法，因为运行库（xlsx）仍然会崩溃程序并抛出警告。我是否需要以某种方式回滚到Java SE 6运行时，或者有没有办法使用我安装的最新版本？

This did not do the trick because running library(xlsx) still crashes the program and throws a warning. Do I need to somehow roll back to Java SE 6 runtime, or is there a way to use the latest version I have installed?

这个SO帖子似乎是相关的，但我不清楚安装Java的安装解决方案6.答案链接到似乎过时的苹果支持页面。

This SO post seems to be related, but I am not clear about the propsoed solution to install Java 6. The answer links to an apple support page that seems out of date.

我不熟悉Java，所以我可以使用一些建议。

I'm not familiar with Java, so I could use some advice.
