无法在Mac OS 10.11上加载R xlsx软件包

Question

我可以加载rJava和xlsxjars包,但是当我执行库(xlsx)时,我得到了"无法加载JVM".以下是我的详细信息.

OS版本:

$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.11
BuildVersion:   15A284

Java版本:

$ java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode)

Java路径:

$ which java
/usr/bin/java

Java主页:

$ /usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home

R版本:

$ R --version
R version 3.2.3 (2015-12-10) -- "Wooden Christmas-Tree"
Copyright (C) 2015 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin13.4.0 (64-bit)

我如何推出R:

$ LD_LIBRARY_PATH=$(/usr/libexec/java_home)/jre/lib/server: open -a RStudio

成功加载rJava和xlsxjars包:

> library(rJava)
> library(xlsxjars)

尝试加载xlsx包失败:

> library(xlsx)
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
Error : .onLoad failed in loadNamespace() for 'xlsx', details:
  call: .jinit()
  error: JNI_GetCreatedJavaVMs returned -1
Error: package or namespace load failed for ‘xlsx’

R配置:

不幸的是,这些符号链接技巧并没有帮助我.但是,我在stackoverflow上发现了类似的问题!(在其他地方;))这个通过以下方式为我工作:

1. 在终端中输入以下内容以正确重新链接Java:

   sudo R CMD javareconf
   

2. 回到R(或RStudio)从源代码安装rJava包:

   install.packages("rJava",type='source')
   

希望这可以帮助!

我也有加载openNLP,xlsx,RWeka等软件包的问题,​​并得到了和你一样的错误信息.但最后这个命令在OS X 10.11.3上对我有用: sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

基本上，只需按照此处描述的操作即可： https://oliverdowling.com.au/2015/10/09/oracles-jre-8-on-mac-os-x-el-capitan/

简短版本：来自 Oracle 的 d/l Java JRE 作为 tar 文件 http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

然后将其放入您的终端（对于 sudo，需要您的密码）：

cd ~/Downloads
tar -xzf `ls -1r jre-*-macosx-x64.tar.gz | head -1`
cd `ls -1rd jre*/ | head -1`
defaults write `pwd`/Contents/Info.plist JavaVM -dict-add 'JVMCapabilities' '<array><string>JNI</string><string>BundledApp</string><string>CommandLine</string></array>'
plutil -convert xml1 Contents/Info.plist
sudo mv `pwd` /Library/Java/JavaVirtualMachines/
mkdir -p Contents/Home/bundle/Libraries
cd Contents/Home/bundle/Libraries
ln -s ../../lib/server/libjvm.dylib libserver.dylib

在我的 OS X 10.11 上运行良好
