在 R 中安装 tabulizer 包

Question

I am using R version 3.4.0. My PC is 64 bit windows 10.

I wanted to extract dataframes from PDF documents in R.

I tried to install tabulizer package using github but i am getting the following error.

> ghit::install_github(c("ropenscilabs/tabulizerjars", "ropenscilabs/tabulizer"), INSTALL_opts = "--no-multiarch")
also installing the dependencies ‘httpuv’, ‘sourcetools’

also installing the dependency ‘rJava’

Answer 1

Most of the problems are cost by the 64 bit setting in your R session. If you want to use 'tabulizer' set the R session to 32 bit. If you are running a GUI, change the setting in there is the easiest way. If you are using eg R-studio see https://support.rstudio.com/hc/en-us/articles/200486138-Using-Different-Versions-of-R .

After that run

install.packages("remotes") # get Package if you don't have it

library(remotes)

remotes::install_github(c("ropensci/tabulizerjars", "ropensci/tabulizer"), INSTALL_opts = "--no-multiarch", dependencies = c("Depends", "Imports"))

If this results in errors install the packages one by one

install.packages("plyr") # get Package if you don't have it

library(plyr)

packs <- c('stringi', 'httpuv', 'digest', 'htmltools', 'sourcetools', 'evaluate', 'markdown', 
           'stringr', 'yaml', 'rJava', 'testthat')

laply(packs, function(x){
  install.packages(x)  
  readline(prompt="Press [enter] to continue")
}
  )

If there are errors post them on Stack. If none of the packs gives an error (therefore the Press [enter] to continue), you can install tabulizer with

remotes::install_github(c("ropensci/tabulizerjars", "ropensci/tabulizer"), INSTALL_opts = "--no-multiarch", dependencies = c("Depends", "Imports"))
