我一直在尝试通过ipython笔记本安装RWeka for R,但是我遇到了错误。我有ubuntu 16.10

我尝试过以下命令

sudo R CMD javareconf

sudo R

install.packages("rJava",type="source")

library/3.3’

最后我跑

library("RWeka")

我收到以下错误。任何帮助将不胜感激。

"Error: package or namespace load failed for ‘RWeka’
Traceback:

1. library("RWeka")
2. stop(gettextf("package or namespace load failed for %s", 
sQuote(package)), 
 .     call. = FALSE, domain = NA)"

1 个答案:

答案 0 :(得分:0)

您可以按照以下说明进行操作:

$ cd ~/

$ sudo -i

$ apt-get install r-cran-rjava

$ apt-get update

$ apt-get install openjdk-8-jdk

(版本8似乎没有错误!)

$ rm -rf /usr/lib/jvm/default-java

(我个人没有默认的java文件,但是您可以检查它是否在您的计算机上)

$ ln -s /usr/lib/jvm/java-8-openjdk-amd64/ /usr/lib/jvm/default-java

$ R CMD javareconf

$ R

$ install.packages(“RWeka”)
