Question

我正在尝试在Rstudio服务器环境中使用rJava库。当我发出：

库（rJava）

我不断收到此错误：

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 '/opt/microsoft/ropen/3.5.1/lib64/R/library/rJava/libs/rJava.so':
  libjvm.so: wrong ELF class: ELFCLASS32

我验证了Java和R发行版都是64位。

R.Version()
$system
[1] "x86_64, linux-gnu"

java -version:

Java HotSpot(TM) 64-Bit Server VM

我通过执行ls确实看到了文件：

ls -l /opt/microsoft/ropen/3.5.1/lib64/R/library/rJava/libs/rJava.so
-rwxr-xr-x 1 root root 365280 Sep 20 15:31 /opt/microsoft/ropen/3.5.1/lib64/R/library/rJava/libs/rJava.so

有什么想法吗？

我执行了@megatron用户推荐的

sudo R CMD javareconf

我收到此错误：
