安装包rweka时出错，但rjava是最新的

Question

我正在尝试安装RWeka包。我安装了java版本8，但我一直收到这个错误。有人能帮上忙吗？

> install.packages('RWeka')

There is a binary version available but the source version is later:
  binary source needs_compilation
RWeka 0.4-26 0.4-33             FALSE

Answer 1

根据经验，我相信Java和Java Offline是有区别的。

尝试从http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html安装x86/x64离线版本(一个便于保存的链接)

Answer 2

如果您使用的是最新的Java，只需打开终端并运行

sudo R CMD javareconf

然后在R会话中，

来源类型(“rJava”，

=‘install.packages’)

install.packages("RWeka")
