错误:无法加载刚刚安装的包 [英] error: unable to load installed packages just now

问题描述

当我尝试在 Eclipse 中运行 R 控制台时，出现此错误:

When I tried to run the R console in Eclipse, I got this error:

....Please make sure that R package 'rj' (1.1 or compatible) is installed...

所以我尝试像这样在 R 控制台中安装它:

So I tried to install it in the R console like this:

install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")

并收到此错误:

 ** testing if installed package can be loaded
 Error : .onLoad failed in loadNamespace() for 'rj.gd', details:
 call: dyn.load(file, DLLpath = DLLpath, ...)
 error: unable to load shared object '/home/alex/R/x86_64-pc-linux-gnu-library/2.15/rj.gd/libs/rj.gd.so':
 libjvm.so: cannot open shared object file: No such file or directory
 Error: loading failed
 Execution halted
 ERROR: loading failed

并且我发现在使用以下方法安装 rJava 时:install.packages("rJava") 得到类似的错误:

and I found that when installing rJava using: install.packages("rJava") gets a similar error:

** testing if installed package can be loaded
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/home/alex/R/x86_64-pc-linux-gnu-library/2.15/rJava/libs/rJava.so':
libjvm.so: cannot open shared object file: No such file or directory
Error: loading failed
Execution halted
ERROR: loading failed

当我运行 sudo R CMD javareconf 时，我得到了这个输出:

When I run sudo R CMD javareconf,I got this output:

Java interpreter : /usr/bin/java
Java version     : 1.7.0
Java home path   : /usr/lib/jvm/java-7-oracle/jre
Java compiler    : /usr/bin/javac

Java archive tool: /usr/bin/jar
NOTE: Your JVM has a bogus java.library.path system property!

JNI linker flags : -L$(JAVA_HOME)/lib/amd64 -L$(JAVA_HOME)/lib/amd64/server -ljvm
JNI cpp flags    : -I$(JAVA_HOME)/../include -I$(JAVA_HOME)/../include/linux

Updating Java configuration in /etc/R
Done.

顺便说一下，我的配置是:

by the way,my configuration is:

Ubuntu 11.10 64bit
Eclipse 3.7
Oracle-1.7-jdk
R version 2.15.1 

推荐答案

我找到了解决方案:

export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-oracle/lib/amd64:/usr/lib/jvm/java-7-oracle/jre/lib/amd64/server

然后

sudo R CMD javareconf

注意:路径 (java-7-oracle) 需要根据您的 Java 安装进行更新.

Note: The path (java-7-oracle) needs to be updated based on your Java installation.
