I am trying to install the webdriver package but there might be an issue with my Dockerfile and the way I run the webdriver::install_phantomjs() function.

My Dockerfile looks like this.

FROM rocker/verse

RUN install2.r --error \
  rJava \
  plumber \
  webdriver \
  mailR \
  DBI \
  RPostgres

RUN R -e 'webdriver::install_phantomjs()'

RUN rm -rf /tmp/downloaded_packages/ /tmp/*.rds

The error I get is below. First the file is downloaded and then the errors begin.

2019-10-16 17:33:29 (7.79 MB/s) - ‘phantomjs-2.1.1-linux-x86_64.tar.bz2’ saved [23415665/23415665]

Execution halted
The command '/bin/sh -c R -e 'webdriver::install_phantomjs()'' returned a non-zero code: 1

I hope someone can help.

I can't says what going on in your dockerfile but just to share about webscraping, know that phantomJS is no more maintained.There is other tools that could do the job as well
