Problem in installing mclust package R

Question

[Raheleh]

Hello,

I tried to install mclust package R in RStudio using different ways

install.packages("mclust")
devtools::install_github("cran/mclust")
biocLite('mclust')

but I get this error:

* installing *source* package ‘mclust’ ...

Can anyone help me out? Many thanks!

This is not a bioinformatics question. Try on StackOverflow.

Anyway, the error message indicates that the compiler can't find the gfortran library. This is part of the gcc compiler suite but may have to be installed separately on some systems, e.g. on Ubuntu, try

sudo apt-get install gfortran
