Problem:
While installing some R package, you see an error message like
/bin/bash: libpng-config: command not found read.c:3:10: fatal error: png.h: No such file or directory 3 | #include | ^~~~~~~ compilation terminated. make: *** [/usr/lib/R/etc/Makeconf:168: read.o] Error 1
Solution:
You need to install the libpng
development headers. On Ubuntu, you can do that using
sudo apt -y install libpng-dev
