使用install.packages("rJava")命令安装rJava时出现以下错误:

尝试使用此代码在我的14.10 ubuntu上的R上安装rJava包

if (!require(rJava)) install.packages('rJava')

几乎没有与java相关的错误,包括jni问题,重新安装jdk后,并尝试再次运行相同的代码,得到了该错误

Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/usr/local/lib/R/site-library/rJava/libs/rJava.so':

嗨,我有来自cran的rJava包的问题.

我安装了

sudo apt-get install openjdk-7-jdk
sudo apt-get install r-cran-rjava

跑了

sudo R CMD javareconf
# Java interpreter : /usr/bin/java
# Java version     : 1.7.0_55
# Java home path   : /usr/lib/jvm/java-7-openjdk-amd64/jre
# Java compiler    : /usr/bin/javac
# Java headers gen.: /usr/bin/javah
# Java archive tool: /usr/bin/jar

然后我尝试运行R并加载rJava并得到以下错误:

R
> library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/usr/lib/R/site-library/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such …

当我想加载rJava时出错.JDK已安装.(我在CentOS VM上运行R(cloudera demo vm cdh3u4))

> library(rJava)

Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/home/cloudera/R/x86_64-redhat-linux-gnu-library/2.15/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such file or directory
Error: package/namespace load failed for ‘rJava’

LD_LIBRARY_PATH设置有问题吗？如果是,我该如何解决？我需要运行rJava来安装rhdfs.

更多信息(如果需要):

[cloudera@localhost ~]$ java -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

我遇到了这个问题中讨论的相同错误消息,归结为:

Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/home/anh/Rlibs/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such file or directory

问题是,在答案之后(即设置LD_LIBRARY_PATH指向libjvm.so)在命令行中解决了我的问题R,但Rstudio libjvm.so仍然无法找到.

系统规格:Ubuntu 14.04,R 3.1.1,Rstudio Desktop 0.98,apt-get install r-cran-rjava完成
