问题描述
在R3.0.1上安装rJava时遇到了这个问题:配置:错误:一种或多种JNI类型与相应的本机类型不同"
I have came across this problem while installing rJava on R3.0.1:"configure: error: One or more JNI types differ from the corresponding native type"
详细信息附在下面.我搜索了类似的问题，但是我的问题有点棘手，许多提议的解决方案要么无效，要么无法尝试，因为我在服务器上工作，而该服务器没有对系统库的写访问权.
The detailed message is attached below.I searched for similar problems but my issue is a little trickier and many proposed solutions either didnt work or I could not try, because I am working on a server which I do not have write access to system libraries.

R :R3.0.1，我下载了源代码，并将其放在主目录中，并从源代码构建了R.
R: R3.0.1, I downloaded the source, put in my home directory, and built R from source.
rJava :我运行了'install.packages("rJava")'，在安装过程中我得到了:
rJava: I ran 'install.packages("rJava")', during installation I got:

由于我只能远程访问服务器，因此我无权访问主目录/home/me之外的任何内容.
Since I can only access the server remotely, I do not have write access to anything outside my home directory /home/me.

推荐答案
只要我尝试以普通用户身份安装(Linux，Debian)，在R版本3.0.2中尝试install.packages("rJava")时都会遇到相同的问题. .以root身份运行install.packages("rJava")没问题.然后，尝试library(rJava)可以为root用户工作，但不能作为我的用户:
I ran into the same problem trying to install.packages("rJava") in R version 3.0.2, as long as I tried to install as ordinary user (Linux, Debian). There was no problem running install.packages("rJava") as root. Then, trying library(rJava) worked for root but not for me as a user:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/usr/usr.local.original.Debian/lib/R/site-library/rJava/libs/rJava.so':
libjvm.so: cannot open shared object file: No such file or directory
添加环境变量JAVA_HOME和LD_LIBRARY_PATH所需的此问题到~/.login(按照在):
This problem required to add the environment variables JAVA_HOME and LD_LIBRARY_PATH to ~/.login (following instructions found at Trouble in Setting Java Environment Path on Ubuntu (libjvm.so: cannot open shared object file: No such file or directory)):
setenv JAVA_HOME /usr/lib/jvm/java-7-oracle/
setenv LD_LIBRARY_PATH $JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server
# For c-shell; for bash, it would have to be:
export JAVA_HOME=/usr/lib/jvm/java-7-oracle/
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server
因此，您将需要让系统管理员为您安装rJava，然后设置您的环境变量，当然还要在R中设置您自己的.libPaths()以便找到rJava.
So, you would have to have a system administrator install rJava for you, then set your environment variables and, of course, set your own .libPaths() in R such as to find rJava.
