我正在尝试rJava在Win 7 64位的计算机上安装.我跑的时候
install.packages("rJava")
一切似乎都很好:

但是当我尝试加载库时,library(rJava)我收到以下错误:
Error : .onLoad failed in loadNamespace() for 'rJava', details:

Error: package/namespace …我最近从OSX Mountain Lion"升级"到Yosemite,从R 3.1.3升级到3.2.升级之后,当我打开R或RStudio时,我收到一条弹出消息,说我需要安装Java 6.此外,加载rJava或依赖于rJava的任何软件包(例如xlsx)导致RStudio崩溃(R也崩溃了当我通过R.app直接打开尝试这个).
尝试在Stack Overflow和其他地方找到一些修复程序后(下面有更多详细信息),我正处于加载rJava或任何依赖的程序包rJava不再导致R崩溃的程度,但会导致以下错误:
library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:

Reason: image not found
Error: package or namespace load failed for ‘rJava’
但是,如果我从命令行调用R然后加载rJava或依赖的任何包rJava,它似乎工作(或至少我没有得到任何错误消息).
我已经尝试了一些不同的尝试修复,其中一些已经修改了几次,并且不能完全记住我按照什么顺序做了什么(没有意识到这将是如此的泥潭并且并没有真正保持跟踪) ,但这是它的要点:

我在StackOverflow上提到了各种帖子,并尝试相应地进行更改,但没有任何效果.以下是我解决问题的各个步骤:
if (Sys.getenv("JAVA_HOME")!="")
Sys.setenv(JAVA_HOME="")
library(rJava)
这没用.
然后我尝试了这个:
options(java.home="C:\\Program Files\\Java\\jre1.8.0_91\\")
library(rJava)
这也不起作用.
我的jvm.dll位于我的Windows 7 64位操作系统中的这个位置 - C:\ Program Files(x86)\ Java\jre1.8.0_91\bin\client
我还在C:\Program Files (x86)\Java\jre1.8.0_91\bin\client我的环境变量中添加了我的PATH变量并重新启动了RStudio并尝试再次安装和加载rJava.这也行不通.
如果有人能帮我解决这个问题,我真的很感激.
多谢你们!

我尝试用最新版本重新安装Java和R程序,但仍然遇到这些错误..我可以知道如何解决这个问题吗？非常感谢你!
我已经看到了一些与此相关的帖子...但是我看到的所有建议的解决方案似乎都不起作用....我在EC2实例中运行R并运行以下命令尝试安装rJava但无济于事...任何帮助将不胜感激.
