在Mac El Capitan上安装和加载rJava时遇到问题 [英] trouble installing and loading rJava on mac El Capitan

问题描述

在安装rJava时遇到问题，尝试了大多数故障排除步骤此处，并且没有"工作.

Have issue installing rJava, tried most troubleshooting steps here and doesn't work.

返回错误

Loading required package: rJava
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     '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/    rJava.so':

我正在使用R/Rstudio和Mac El Capitan的最新版本

I'm on latest ver of R/Rstudio and Mac El Capitan

我也尝试了这种方法1无效

I also tried this method 1 which didn't work

sudo R CMD javareconf

然后，在R解释器中:

install.packages('rJava', type='source')
install.packages('xlsx', type='source')

方法2

sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

返回错误ln:/usr/local/lib/libjvm.dylib:文件存在

error returned ln: /usr/local/lib/libjvm.dylib: File exists

方法3 install.packages("rJava"，type ="binary") 错误:tar:无法设置默认语言环境

method 3 install.packages("rJava", type = "binary") error: tar: Failed to set default locale

处理默认语言环境错误

system("defaults write org.R-project.R force.LANG en_US.UTF-8")

在加载rJava时，仍然出现相同的错误:

upon loading rJava, still same error:

image not found

因此看起来它已安装但无法加载

So looks like it's installed but won't load

推荐答案

问题是rJava无法安装在RStudio(Version 1.0.136)中.以下内容对我有用(macOS Sierra version 10.12.6)(在此处找到):

The problem was rJava wont install in RStudio (Version 1.0.136). The following worked for me (macOS Sierra version 10.12.6) (found here):

第1步:从此处下载并安装javaforosx.dmg

Step-1: Download and install javaforosx.dmg from here

步骤2:接下来，从RStudio内部运行命令:

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