Question

我在ubuntu 16.04上工作（在docker容器内）。

已安装libroffice并正常工作。

我可以在命令行中使用它：

R version 3.3.2 (2016-10-31) -- "Sincere Pumpkin Patch"

R is a collaborative project with many contributors.
Type 'contributors()' for more information and
'citation()' on how to cite R or R packages in publications.

Type 'demo()' for some demos, 'help()' for on-line help, or
'help.start()' for an HTML browser interface to help.
Type 'q()' to quit R.

Warning: failed to read path from javaldx
/usr/lib/libreoffice/program/soffice.bin: error while loading shared libraries: libreglo.so: cannot open shared object file: No such file or directory

但如果我尝试在R中做同样的事情：

#lang racket

(define str
  "Beebe a reeble to one niner big druppy bonker watz. ")

(with-output-to-file "/tmp/foo.txt"
  (λ ()
    (for ([i (in-range (/ 500000 10))])
      (displayln str))))

我不明白这个共享库错误... 有什么想法吗？

此致

只需在目录.conf中添加以/etc/ld.so.conf.d/结尾的文件，或通过LD_LIBRARY_PATH环境变量添加一个命令，永久设置库路径：

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

编辑：实际上，也许还有其他错误，因为这里也适用于env.var：

edd@max:~$ R
