我在 ubuntu 16.04 上工作（在 docker 容器内）。
libreoffice 已安装并且工作正常。
我可以通过命令行使用它：
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:/#
但如果我尝试在 R 中做同样的事情：

我不明白这个共享库错误......
任何想法 ？

只需添加以以下结尾的文件即可永久设置库路径.conf在目录中/etc/ld.so.conf.d/，或者仅针对通过的一个命令LD_LIBRARY_PATH环境变量：
edd@max:~$ LD_LIBRARY_PATH=/usr/lib/libreoffice/program/ R

Edit:实际上，也许你最后还有其他问题，因为这里它也适用于 env.var：
