OsX中Rstudio中缺少rJava图像

当我尝试在OsX High Sierra上的RStudio中加载库（“rJava”）时，我得到了前面提到的关于图像不存在的错误：

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 '/Users/ognjenmilicevic/RPlay/Methylation_Mayo_Vesna_Garovic/libs/rJava/libs/rJava.so':

  Referenced from: /Users/ognjenmilicevic/RPlay/Methylation_Mayo_Vesna_Garovic/libs/rJava/libs/rJava.so
  Reason: image not found

我尝试重新配置Java，但错误仍然存在：

卸下并重新安装该软件包没有帮助。我尝试使用以下方法指向我的版本：

dyn.load('/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home/lib/server/libjvm.dylib')

错误仍然存在。当作为命令运行时，它始终在R中工作。路径“/Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/lib/server/libjvm.dylib”来自何处？如何将其更改为指向我的安装？

看起来您的安装有点混乱或

rJava

通过调用以下命令，您始终可以检查使用了哪个版本的Java（在构建

rJava

）：

> otool -L /Library/Frameworks/R.framework/Resources/library/rJava/libs/rJava.so
/Library/Frameworks/R.framework/Resources/library/rJava/libs/rJava.so:
    rJava.so (compatibility version 0.0.0, current version 0.0.0)
    /Library/Java/JavaVirtualMachines/jdk-11.0.1.jdk/Contents/Home/lib/server/libjvm.dylib (compatibility version 1.0.0, current version 1.0.0)
    /Library/Frameworks/R.framework/Versions/3.6/Resources/lib/libR.dylib (compatibility version 3.6.0, current version 3.6.0)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1259.11.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

对你来说，你必须打电话

> otool -L /Users/ognjenmilicevic/RPlay/Methylation_Mayo_Vesna_Garovic/libs/rJava/libs/rJava.so

确保已安装此Java版本：

jdk-11.0.1.jdk

。如果您没有，并且您想在当前版本的

JDK

中安装

rJava

-例如：

JDK-10.0.1.JDK

，请按照以下步骤操作：

另外，请记住，在macOS中，默认的Java是最新的。这意味着

RStudio

将选择启用的数字最高的版本

您可以通过调用

> cd /Library/Java/JavaVirtualMachines/jdk-11.0.4.jdk/Contents
> mv Info.plist Info.plist~

上述命令将使此Java版本对macOS“不可见”

一旦遵循这些步骤（如链接文章中所述），您将能够从R和RStudio运行Java

感谢您的详细回答。不幸的是，我不能让它任何工作。a） 我在互联网上的任何地方都找不到jdk-11.0.1.jdk。b） 我只有一个Java版本，10.0.1。我不知道这11个东西是从哪里来的。它看起来像是使用jdk-11编译的

rJava版本。您可以从openjdk项目页面（或Oracle）下载jdk
