Installing packages in R gives the following errors - r

Question

When trying to install some packages such Rcmdr or factoextra while on R in terminal (after upgrade to R 4.0.0 on Archlabs) the following errors shows up:
* installing *source* package ‘SparseM’ ...
** package ‘SparseM’ successfully unpacked and MD5 sums checked
** using staged installation
** libs
gfortran -fno-optimize-sibling-calls -fpic -g -O2 -c bckslv.f -o bckslv.o
/usr/local/bin/gfortran: /usr/local/bin/gfortran: cannot execute binary file
make: *** [/usr/lib64/R/etc/Makeconf:190: bckslv.o] Error 126
ERROR: compilation failed for package ‘SparseM’
* removing ‘/usr/lib/R/library/SparseM’
and this one :
* installing *source* package ‘readr’ ...
** package ‘readr’ successfully unpacked and MD5 sums checked
** using staged installation
** libs
g++ -std=gnu++11 -I"/usr/include/R/" -DNDEBUG -I'/usr/lib/R/library/Rcpp/include' -I'/usr/lib/R/library/BH/include' -D_FORTIFY_SOURCE=2 -I. -Ircon -fpic -march=x86-64 -mtune=generic -O2 -pipe -fno-plt -c Collector.cpp -o Collector.o

| ^~~~~~~~~

make: *** [/usr/lib64/R/etc/Makeconf:176: Collector.o] Error 1
then followed by a bunch of
ERROR: dependencies ‘dendextend’, ‘FactoMineR’, ‘ggpubr’, ‘ggrepel’, ‘tidyr’ are not available for package ‘factoextra’
* removing ‘/usr/lib/R/library/factoextra’
following each dependencies produces the same errors with different new dependencies.
P.S: I'm a normie so please bear with me.

I had a similar error while installing 'ape'. For me it worked to reinstall the current version of the 'Rcpp' package:
install.packages('Rcpp')
Hope it works for you too !
