Recently, I started to learn R language by using Rstudio, but when I tied to install some packages i had some problems.

When I try to install the "rvest" package, it give the errors as following：

    > install.packages("rvest")Installing package into ‘/home/zm/R/x86_64-pc-linux-gnu-library/3.4’
    (as ‘lib’ is unspecified)also installing the dependencies ‘openssl’, ‘httr’

The downloaded source packages are in ‘/tmp/RtmpuOfZU9/downloaded_packages’

I think the following is the key point of my problem:

The configuration failed because openssl wasn't found.

I tried to install:

  • deb: libssl-dev (Debian, Ubuntu, etc)
  • rpm: openssl-devel (Fedora, CentOS, RHEL)
  • csw: libssl_dev (Solaris)
  • brew: [email protected] (Mac OSX)

If openssl is already installed, check that 'pkg-config' is in your PATH and PKG_CONFIG_PATH contains a openssl.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=...'

I also started to install the packages in Ubuntu. However, I even didn't success to install them in Ubuntu.

And I also tried the following method: export PKG_CONFIG_PATH=/cv/lib:$PKG_CONFIG_PATH Without success..

Could somebody help me to figure out what happened, thank you very much!

I have the same problem as You. You need to do a few thing (nuclear option but it should work):

sudo add-apt-repository 'deb 
https://mirrors.nic.cz/R/bin/linux/ubuntu trusty/'
sudo apt-get update
sudo apt-get install r-base-dev
sudo apt-get install libxml2-dev
sudo apt-get install libssl-dev
sudo -i R

or if You use rstudio:

sudo -i rstudio

and in R:

install.package('rvest')

I did all above and maybe 

pkg-config rvest

in a console and it worked. R shoud show during package installation some messages titled as You can see "anticonf error" and there it should be written what else should You install. My list consisted those packages. I see that some time has passed since Your herby request, but it should be answered for the sake of next generations.

Just install libssl-dev using aptitude or apt as stated in the error message you report.

I had the same problem of openssl not installing from rstudio on OSX when trying to install tidyverse package.

The solution for me was to try to install openssl from r prompt, I then received instruction from the shell under "-- ANTICONF ERROR --":

For me under OSX, I just had to install [email protected] using the package manager 

brew install [email protected]

I could then install tidiverse normally from R. then use it from rstudio.

I thus believe that you should be able to install rvest from Rstudio once you will have installed libssl-dev from the shell, using something like 

aptitude install libssl-dev

or similar apt command
