rJava加载错误

像一群人一样,我无法在RStudio中加载rJava - 在直接使用R GUI时,同样的问题也会重现。

这是错误:

> require(rJava)
Loading required package: rJava
Error: package or namespace load failed for ‘rJava’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so':
  dlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: @rpath/libjvm.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
  Reason: image not found

我尝试了很多方面,包括从命令行重新配置:

sudo R CMD javareconf -n

Java interpreter : /usr/bin/java
Java version     : 1.8.0_144
Java home path   : /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre
Java compiler    : /usr/bin/javac
Java headers gen.: /usr/bin/javah
Java archive tool: /usr/bin/jar
Non-system Java on macOS

trying to compile and link a JNI program

JAVA_HOME        : /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre
Java library path: $(JAVA_HOME)/lib/server
JNI cpp flags    : -I$(JAVA_HOME)/../include -I$(JAVA_HOME)/../include/darwin
JNI linker flags : -L$(JAVA_HOME)/lib/server -ljvm

当我检查options("java.home")时,它已设置为NULL,因此我将其设置为以下内容:

> options("java.home"="/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre")

我还重新安装了Java SE Development Kit 8,然后重新安装了rJava

无论如何,我仍然会遇到同样的错误。

这是我的会话信息:

任何想法都会受到赞赏。

我有类似的问题。最快的解决方案是手动加载dylib

dyn.load('/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre/lib/server/libjvm.dylib')
require(rJava)

如果上述解决方案有效,则通过将此命令添加到终端来存在长期解决方案。

sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

找到此解决方案here。您不再需要每次都手动加载dylib

在Mac OX系统上重新安装java时,需要关闭所有r会话,然后使用系统命令行R CMD javareconf

答案 2 :(得分:0)

这需要我花费大量时间在mac OS中解决。

你可以试试这些:

R 3.4, rJava, macOS and even more mess ;)和此R, Java, rJava and macOS adventures

你可以在那里找到非常详细的说明。但请注意,有些人会按照这些说明面临系统特定问题:(

并且很难找到能够解决人们发现的所有问题的解决方案。

对我来说,这条指令做到了:
