configuration failed for xml2 while installing tidyverse in r studio - r

Question

system: ubuntu 18.04
Rstudio version 3.4.4
Whenever i try to install tidyverse this error comes up, how do i add the directory containing the lib-curl to the package configuration search path?
installing source package ‘curl’ ...
package ‘curl’ successfully unpacked and MD5 sums checked
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcurl' found

Answer 1

Install these missing dependencies before installing R packages:
sudo apt install libcurl4-openssl-dev libssl-dev libxml2-dev

Answer 2

Quit R and open up a command window and confirm that libcurl is indeed not installed on Ubuntu
apt list --installed | grep libcurl
You should see no results.
Install the package
sudo apt update
sudo apt install libcurl4-openssl-dev
Open up R and reinstall tidyverse.
If you still get error messages in R, you might have to install additional missing Linux packages by repeating similar steps.
