I tried to step through the workaround but i also ended up with this error onLoad in loadNamespace() für ‘rJava’ fehlgeschlagen, Details:Īufruf: dyn.load(file, DLLpath = DLLpath, …)įehler: kann shared object ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so’ nicht laden:ĭlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so When i try to start rjava i get the following errorįehler: package or namespace load failed for ‘rJava’: *** Java interpreter doesn’t work properly.

To overcome this issue, you need to create fake Java home directory – without “/Home” in the name.Ĭd /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/ContentsĮxport JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/RHomeĪnd run javareconf with settings allowing to compile the code Half of your settings point to JDK and other half to JVM installed by Apple. javareconf assumes that whenever you JAVA_HOME matches “/Home$” using grep, it points to system based Java installation – instead of Oracle’s one. To get Java running in R, you call javareconf as followsīut, there is a small but. However, if you try to use JDK with R, there is a small surprise behind the corner. If you tree this one, you will see that structure is quite similar to other systems (e.g. # if you run it without any switches it will show currently used Java Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home In macOS you have this special command: java_homeġ.8.0_11, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Homeġ.8.0_05, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home First of all, you have to play with JAVA_HOME. │ │ ├── Resources -> Versions/Current/ResourcesĪnyway, if you want to configure R such way it works properly with JVM, you have to make some tweaking. │ │ │ ├── Resources -> Versions/Current/Resources ├── Resources -> Versions/Current/Resources ├── Frameworks -> Versions/Current/Frameworks # this is the place where Oracle based Java will be installedĪpple’s layout is quite different comparing to what you expect from typical JDK installation. # this is the place where Java Framework resides First of all, you can have different Java installations: Oracle based or system based.

In fact, Java itself is a mess when it comes to macOS. For updated info (for R3.4) take a look HERE.
