Hi,

I am unable to install tesseract package in rstudio. I get the following error message.

install.packages("tesseract")
Installing package into ‘/home/rstudio-user/R/x86_64-pc-linux-gnu-library/3.5’
(as ‘lib’ is unspecified)
trying URL 'http://package-proxy/src/contrib/tesseract_4.0.tar.gz'

  • installing source package ‘tesseract’ ...

    Perhaps you should add the directory containing `tesseract.pc'
    to the PKG_CONFIG_PATH environment variable

  • rpm: tesseract-devel leptonica-devel (Fedora, CentOS, RHEL)
  • csw: libtesseract_dev (Solaris)
  • brew: tesseract (Mac OSX)
    If tesseract is already installed, check that 'pkg-config' is in your
    PATH and PKG_CONFIG_PATH contains a tesseract.pc file. If pkg-config
    is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
    R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

ERROR: configuration failed for package ‘tesseract’

    Warning in install.packages :

Please help.

Thanks,

The relevant part of your error message is below:

Configuration failed because tesseract was not found. Try installing:
deb: libtesseract-dev libleptonica-dev (Debian, Ubuntu, etc)
rpm: tesseract-devel leptonica-devel (Fedora, CentOS, RHEL)
csw: libtesseract_dev (Solaris)
brew: tesseract (Mac OSX)

Depending on what your system is, you'll need to install one of these libraries outside of R on which tesseract (the R package) depends.

From the home directory and reference to package-proxy, you appear to be using rstudio.cloud.

This came up just the other day in this topic.
