当我尝试在 Eclipse 中运行 R 控制台时,出现以下错误:
....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:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")
并得到这个错误:
** 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
我发现在安装 rJava 时使用:install.packages("rJava")
会出现类似的错误:
** 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
当我运行时sudo R CMD javareconf
,我得到了这个输出:

Java compiler : /usr/bin/javac
