R中系统功能的共享库问题 [英] shared library issue with the system function in R

问题描述

我在ubuntu 16.04上工作(在docker容器内部).

I work on ubuntu 16.04 (inside a docker container).

libroffice已安装并且可以正常工作.

libroffice is installed and work fine.

我可以在命令行中使用它:

I can use it with command line:

root@07ff3fbcb3cd:/# libreoffice --version
LibreOffice 5.2.4.2.1 20m0(Build:2)
root@07ff3fbcb3cd:/# libreoffice --headless --convert-to pdf --outdir . rapport.docx                                                            
convert /rapport.docx -> /rapport.pdf using filter : writer_pdf_Export
root@07ff3fbcb3cd:/# 

但是，如果我尝试在R中做同样的事情:

But if I try to do the same in R:

我不了解此共享库错误... 有什么主意吗?

I dont understand this shared library error... Any idea ?

推荐答案

只需永久设置库路径，只需在目录/etc/ld.so.conf.d/中添加以.conf结尾的文件即可，或者仅通过环境变量:

Just set the library path, permanently by adding a file ending in .conf in the directory /etc/ld.so.conf.d/, or just for the one command via the LD_LIBRARY_PATH environment variable:

edd@max:~$ LD_LIBRARY_PATH=/usr/lib/libreoffice/program/ R

实际上，也许其他问题在您的末端是错误的，因为在这里它也可以与env.var一起使用:

Actually, maybe something else is wrong at your end because here it also works with the env.var:

edd@max:~$ R
